AB  - Protein modifications (PMs) are covalent changes occurring on amino acid (AA) side chains of
proteins via enzymatic action or spontaneously. They increase the protein structure complexity
from the level of the genome to the proteome, and can determine their activity and, interactions1.
It has been shown, on myofibrillar fish proteins that oxidative modifications depending on their
saturation can decrease or enhance protein digestability2. Thus in this study shellfish meat samples
were subjected to cooking followed by simulated INFOGEST in vitro gastrointestinal digestion
protocol. Mass Spectrometry and in gel based proteomics, were used to detect PMs and digestion
resistan peptides of raw and cooked shellfish meat samples with a foucs on major shellfish allergens:
sarcoplasmic calcium-binding protein (SBP) and tropomyosin (TPM). Lastly, identified PMs
were marked on TPM alignment from shrimp, oyster and abalone species, to gain insight into their
pattern on the known IgE binding epitopes. Focusing on oxidative PMs, mostly on oxidation of Met,
it was confirmed that, in all shellfish samples, PMs on TPM and SBP were more predominant after
cooking. For instance in abalone, double oxidation of Met was only detected in cooked samples
(sulfone M68 and M81). Another indicator of oxidative stress, 4-hydroxynonenal (HNE), was identified
on shrimp TPM and, notably HNE was 21 times more abundant in the cooked sample. Study
highlights the susceptibility of immunodominant epitopes in major shellfish allergens to oxidative
PMs, which could impact interactions with the immune system in sensitive individuals. Significant
resistance to digestion was demonstrated by paramyosin fragments in abalone and oyster suggesting
the need for further analysis of their allergenicity. SBP of raw shrimp was strikingly resistant
to both gastric and intestinal digestion. Moreover, our results indicate that oxidative modifications
may decrease the stability of proteins like shrimp TPM, making them more digestible in thermally
treated samples, highlighting a potential strategy for reducing allergenicity.

AB  - Meat samples were subjected to thermal processing combined with simulated INFOGEST in vitro gastrointestinal (GI) digestion. Protein modifications (PMs) were screened with commercially available PM-specific antibodies. Specific proteins at 20, 37, 50, and 65 kDa react to more than 3 PM-specific antibodies among meat proteins. Lysine methylation and methionine oxidation were the most prominent PMs in WB. Mass spectrometry confirmed bands at ≈20 kDa as allergenic proteins: sarcoplasmic calcium-binding protein in oyster, 37 kDa as tropomyosin in shrimp, oyster, and abalone. MS-identified PMs of shellfish allergens were aligned to the IgE binding epitopes. GI digestion-resistant peptides of shellfish proteins were identified as paramyosins in oyster and abalone and SBP in shrimp. Our results point to the high susceptibility of immunodominant epitopes of major shellfish allergens to PMs. In TPM, saturation of oxidative modification increases with thermal processing resulting in higher susceptibility of TPM to gastric digestion.

AB  - Oxidative modifications of proteins are key to many applications in biotechnology. Metal-catalyzed oxidation reactions efficiently oxidize proteins but with low selectivity, and are highly dependent on the protein surface residues to direct the reaction. Herein, we demonstrate that discrete inorganic ligands such as polyoxometalates enable an efficient and selective protein oxidative cleavage. In the presence of ascorbate (1 mM), the Cu-substituted polyoxometalate K8[Cu2+(H2O)(α2-P2W17O61)], (CuIIWD, 0.05 mM) selectively cleave hen egg white lysozyme under physiological conditions (pH =7.5, 37 °C) producing only four bands in the gel electropherogram (12.7, 11, 10, and 5 kDa). Liquid chromatography/mass spectrometry analysis reveals a regioselective cleavage in the vicinity of crystallographic CuIIWD/lysozyme interaction sites. Mechanistically, polyoxometalate is critical to position the Cu at the protein surface and limit the generation of oxidative species to the proximity of binding sites. Ultimately, this study outlines the potential of discrete, designable metal oxo clusters as catalysts for the selective modification of proteins through radical mechanisms under non-denaturing conditions.

AB  - Tick bites have been shown to transmit a novel form of severe food allergy, the galactose-α-1,3-galactose (α-Gal) syndrome (AGS). Cellular responses to α-Gal in patients with AGS have, to date, not been thoroughly scrutinized. Therefore, we investigated T and B cell proliferation, activation, and cytokine profiles in response to tick protein extract (TE) and α-Gal-free TE in patients with AGS and in healthy controls. T and B cells from both patients and controls proliferated in response to TE, but significantly more in patients with AGS. B cell proliferation, but not T cell proliferation, in patients with AGS was reduced by removing α-Gal from the TE. In addition, TE induced a clear Th2 cytokine profile in patients with AGS. Expression of CD23 by B cells correlated only to T cell proliferation. However, both B cell proliferation and CD23 expression were reduced when CD40L and IL-4 were blocked. A large portion of the IgG1 and IgE antibodies binding TE in patients with AGS were directed against the α-Gal epitope. We have, for what we believe to be the first time, investigated T and B cell responses to α-Gal carrying tick proteins in patients with AGS, which will be essential for the understanding of the immune response against an allergenic carbohydrate transmitted by ticks.

AB  - The digestion stability of allergen pairs, tropomyosin, TM (fish and seafood allergen), and myosin light chain, MLC (chicken meat allergen) is compared among vertebrates and invertebrates in raw and cooked food matrix under standardized simulated in vitro gastrointestinal (GI) digestion. SDS-PAGE followed by multiple TM and MLC-specific antibodies in semidry WB revealed pepsin resistance of invertebrate TMs (abalone, oyster, shrimp) under diet-relevant conditions (raw, cooked). Vertebrate TMs (chicken, pork, beef) were less stable to digestion except that the raw chicken TM was observed pepsin resistant (not diet-relevant). Vertebrate (chicken) MLC was thermally stable. A new 28 kDa protein bound to anti-MLC antibody in cooked chicken and pork; could be the aggregates of MLC. Raw shrimp MLC showed pepsin resistance among invertebrates. A good correlation was observed between combined resistance of TM and MLC to GI digestion following the diet-relevant thermal treatment and reported protein allergenicity among vertebrates and invertebrates.

AB  - Oxidative modifications of proteins are key to many applications in biotechnology. Metal-catalyzed oxidation reactions efficiently oxidize proteins but with low selectivity, and are highly dependent on the protein surface residues to direct the reaction. Herein, we demonstrate that discrete inorganic ligands such as polyoxometalates enable an efficient and selective protein oxidative cleavage. In the presence of ascorbate (1 mM), the Cu-substituted polyoxometalate K8[Cu2+(H2O)(α2-P2W17O61)], (CuIIWD, 0.05 mM) selectively cleave hen egg white lysozyme under physiological conditions (pH =7.5, 37 °C) producing only four bands in the gel electropherogram (12.7, 11, 10, and 5 kDa). Liquid chromatography/mass spectrometry analysis reveals a regioselective cleavage in the vicinity of crystallographic CuIIWD/lysozyme interaction sites. Mechanistically, polyoxometalate is critical to position the Cu at the protein surface and limit the generation of oxidative species to the proximity of binding sites. Ultimately, this study outlines the potential of discrete, designable metal oxo clusters as catalysts for the selective modification of proteins through radical mechanisms under non-denaturing conditions.

AB  - Cilj ovog rada je bio ispitati regioselektivnost Zr-Wells-Dawson 1:2 polioksometalata (Zr-WD 1:2) na β-laktoglobulinu (BLG) kao model proteinu. Literaturni podaci ukazuju na selektivnost ka kiselim aminokiselinama, kao što su aspartat i glutamat. Kako bismo dobili što pouzdanije rezultate u radu su korišteni nativni BLG (smjesa A i B izoforme), redukovan i alkilovan BLG i pojedinačne izoforme A i B. Rezultati dobijeni reakcijom sa Zr-WD 1:2 ukazuju da dolazi do hidrolize i da je elektroforetski profil različit za sve ispitivane tipove BLG. Zbog uslova reakcije (7 dana na 60 °C) dolazi i do autolize tako da krajnji efekat jeste kombinovani efekat autolize i dejstva Zr-WD 1:2. Bitno za naglasiti jeste to da nakon 24 časa na elektroforetskim profilma se javljaju proizvodi hidrolize, dok autoliza izostaje. Takođe, rezultati su pokazali da Zr-WD 1:2 ne ispoljava isključivu selektivnost ka kiselim aminokiselinama (aspartatu i glutamatu) već dolazi do hidrolize i na drugim aminokiselinama što nije u skladu sa literaturnim podacima u uzorku redukovanog i alkilovanog BLG.

AB  - Post-translational modifications (PTMs) are covalent changes occurring on amino acid side chains of proteins and yet are neglected structural and functional aspects of protein architecture. The objective was to detect differences in PTM profiles that take place after roasting using open PTM search. We conducted a bottom-up proteomic study to investigate the impact of peanut roasting on readily soluble allergens and their PTM profiles. Proteomic PTM profiling of certain modifications was confirmed by Western blotting with a series of PTM-specific antibodies. In addition to inducing protein aggregation and denaturation, roasting may facilitate change in their PTM pattern and relative profiling. We have shown that Ara h 1 is the most modified major allergen in both samples in terms of modification versatility and extent. The most frequent PTM was methionine oxidation, especially in roasted samples. PTMs uniquely found in roasted samples were hydroxylation (Trp), formylation (Arg/Lys), and oxidation or hydroxylation (Asn). Raw and roasted peanut extracts did not differ in the binding of IgE from the serum of peanut-sensitised individuals done by ELISA. This study provides a better understanding of how roasting impacts the PTM profile of major peanut allergens and provides a good foundation for further exploration of PTMs.

AB  - Background: The world’s production of whey is estimated to be more than 200 milliontons per year. Although whey is an important source of proteins with high nutritional value andbiotechnological importance, it is still considered as a by-product of the dairy industry with loweconomic value due to low industrial exploitation. There are several challenges in the separation ofwhey proteins: low concentration, the complexity of the material and similar properties (pI, molecularmass) of some proteins.Methods: A narrative review of all the relevant papers on the present methodologies based on ionexchange and adsorption principles for isolation of whey proteins, known to the authors, was conductedResults: Traditional ion exchange techniques are widely used for the separation and purification ofthe bovine whey proteins. These methodologies, based on the anion or cation chromatographicprocedures, as well as the combination of aforementioned techniques are still preferential methodsfor the isolation of the whey proteins on the laboratory scale. However, more recent research on ionexchange membranes for this purpose has been introduced, with promising potential to be appliedon the pilot industrial scale. Newly developed methodologies based either on the ion exchangeseparation (for example: simulated moving bed chromatography, expanded bed adsorption, magneticion exchangers, etc.) or adsorption (for example: adsorption on hydroxyapatite or activatedcarbon, or molecular imprinting) are promising approaches for scaling up of the whey proteins’purification processes.Conclusion: Many procedures based on ion exchange are successfully implemented for the separationand purification of whey proteins, providing protein preparations of moderate-to-high yieldand satisfactory purity. However, the authors anticipate further development of adsorption-basedmethodologies for the separation of whey proteins by targeting the differences in proteins’ structuresrather than targeting the differences in molecular masses and pI. The complex composite multilayeredmatrices, including also inorganic components, are promising materials for simultaneousexploiting of the differences in the masses, pI and structures of whey proteins for the separation.

AB  - Background: The world’s production of whey is estimated to be more than 200 milliontons per year. Although whey is an important source of proteins with high nutritional value andbiotechnological importance, it is still considered as a by-product of the dairy industry with loweconomic value due to low industrial exploitation. There are several challenges in the separation ofwhey proteins: low concentration, the complexity of the material and similar properties (pI, molecularmass) of some proteins.Methods: A narrative review of all the relevant papers on the present methodologies based on ionexchange and adsorption principles for isolation of whey proteins, known to the authors, was conductedResults: Traditional ion exchange techniques are widely used for the separation and purification ofthe bovine whey proteins. These methodologies, based on the anion or cation chromatographicprocedures, as well as the combination of aforementioned techniques are still preferential methodsfor the isolation of the whey proteins on the laboratory scale. However, more recent research on ionexchange membranes for this purpose has been introduced, with promising potential to be appliedon the pilot industrial scale. Newly developed methodologies based either on the ion exchangeseparation (for example: simulated moving bed chromatography, expanded bed adsorption, magneticion exchangers, etc.) or adsorption (for example: adsorption on hydroxyapatite or activatedcarbon, or molecular imprinting) are promising approaches for scaling up of the whey proteins’purification processes.Conclusion: Many procedures based on ion exchange are successfully implemented for the separationand purification of whey proteins, providing protein preparations of moderate-to-high yieldand satisfactory purity. However, the authors anticipate further development of adsorption-basedmethodologies for the separation of whey proteins by targeting the differences in proteins’ structuresrather than targeting the differences in molecular masses and pI. The complex composite multilayeredmatrices, including also inorganic components, are promising materials for simultaneousexploiting of the differences in the masses, pI and structures of whey proteins for the separation.

AB  - β-lactoglobulin (BLG) is a major whey protein with numerous techno-functional properties desirable for the food industry. Phycocyanobilin (PCB), a bioactive pigment of Arthrospira platensis with health-promoting effects, covalently binds to BLG at physiological pH. This study investigated the effects of this covalent modification on BLG functional properties. The BLG–PCB adduct possesses enhanced antioxidant properties, and bound PCB protects BLG against free radical-induced oxidation. Despite the similar thermal stabilities of BLG and BLG–PCB, BLG–PCB is less susceptible to covalent and noncovalent aggregation under moderate heat treatment (63 °C, 30 min). Blocked thiol group and reduced hydrophobicity due to hindering of hydrophobic residues by bound PCB, as well as the heat-induced transition of β-sheet to α-helix, contributed to the low susceptibility of BLG–PCB to aggregation. BLG–PCB has a higher resistance to pepsin and pancreatin digestion than BLG and unaltered IgE-binding properties. The improved functional properties of BLG–PCB make it a useful ingredient in the food industry.

AB  - Current approaches based on electrophoretic, chromatographic or immunochemical principles have allowed characterizing multiple allergens, mapping their epitopes, studying their mechanisms of action, developing detection and diagnostic methods and therapeutic strategies for the food and pharmaceutical industry. However, some of the common structural features related to the allergenic potential of food proteins remain unknown, or the pathological mechanism of food allergy is not yet fully understood. In addition, it is also necessary to evaluate new allergens from novel protein sources that may pose a new risk for consumers. Technological development has allowed the expansion of advanced technologies for which their whole potential has not been entirely exploited and could provide novel contributions to still unexplored molecular traits underlying both the structure of food allergens and the mechanisms through which they sensitize or elicit adverse responses in human subjects, as well as improving analytical techniques for their detection. This review presents cutting-edge instrumental techniques recently applied when studying structural and functional aspects of proteins, mechanism of action and interaction between biomolecules. We also exemplify their role in the food allergy research and discuss their new possible applications in several areas of the food allergy field.

AB  - The emergence of the coronavirus SARS-CoV-2 has attracted attention of the whole scientific community. The SARS-CoV-2 spike (S) protein plays the most important role in viral attachment to host receptor angiotensin-converting enzyme 2 (ACE2), via the receptor-binding domain (RBD), fusion and entry into the host, and it serves as a target for the development of antibodies, entry inhibitors and vaccines. It has been demonstrated that phycocyanobilin (PCB), a bioactive open-chain tetrapyrrole chromophore of phycocyanin (PC), chromoprotein derived from the cyanobacterium Arthrospira platensis, can bind a plethora of different proteins, both in a noncovalent and covalent manner. This study aimed to investigate interactions of PCB with S protein and RBD respectively. Electrophoretic techniques, fluorescence spectroscopy, and inhibition of S–PCB and RBD–PCB covalent adduct formation using iodoacetamide and N-ethylmaleimide, were employed to examine interactions of PCB with S protein and RBD, while the effects of PCB binding on RBD structure were studied by CD spectroscopy. SDS-PAGE with Zn2+ staining has revealed that PCB covalently binds to both S protein and RBD, via free cysteine residues. Binding constants determined by the fluorescence quenching method were: 2.1×107 M–1 for PCB and S protein and 8.4×104 M–1 for PCB and RBD. Far-UV circular dichroism spectra showed that the binding of PCB influences RBD structure by decreasing the disordered structure content. Due to moderately strong noncovalent interactions of PCB with S protein and RBD, as well as covalent adducts formation, it may exert one of its many bioactive effects via impact on S protein binding to ACE2 receptor.

AB  - : Post-translational modifications (PTMs) are covalent changes occurring on amino acid side
chains of proteins and yet are neglected structural and functional aspects of protein architecture. The
objective was to detect differences in PTM profiles that take place after roasting using open PTM
search. We conducted a bottom-up proteomic study to investigate the impact of peanut roasting on
readily soluble allergens and their PTM profiles. Proteomic PTM profiling of certain modifications
was confirmed by Western blotting with a series of PTM-specific antibodies. In addition to inducing
protein aggregation and denaturation, roasting may facilitate change in their PTM pattern and relative
profiling. We have shown that Ara h 1 is the most modified major allergen in both samples in terms
of modification versatility and extent. The most frequent PTM was methionine oxidation, especially
in roasted samples. PTMs uniquely found in roasted samples were hydroxylation (Trp), formylation
(Arg/Lys), and oxidation or hydroxylation (Asn). Raw and roasted peanut extracts did not differ
in the binding of IgE from the serum of peanut-sensitised individuals done by ELISA. This study
provides a better understanding of how roasting impacts the PTM profile of major peanut allergens
and provides a good foundation for further exploration of PTMs

(Arg/Lys), and oxidation or hydroxylation (Asn). Raw and roasted peanut extracts did not differ
in the binding of IgE from the serum of peanut-sensitised individuals done by ELISA. This study
provides a better understanding of how roasting impacts the PTM profile of major peanut allergens
and provides a good foundation for further exploration of PTMs",

AB  - The high content of vitamins, minerals, antioxidants, and proteins makes red algae Porphyra sp. (Nori) superfood with exceptional health-promoting benefits. Its intense colour originates from R-phycoerythrin (R-PE), phycobiliprotein containing covalently attached tetrapyrrole chromophores: red phycoerythrobilin and orange phycourobilin. The present study aims to characterize the stability of R-PE, a natural colourant with a high potential for application in the food, cosmetic, and pharmaceutical industries. We purified R-PE from dried Nori flakes with a high purity ratio (A560 /A280 ≥5). Far-UV CD spectroscopic showed that α-helix is the dominant secondary structure (75%). The thermal unfolding of α-helix revealed two transitions (Tm1 and Tm2 at 56 and 72°C, respectively), ascribed to the different subunits of R-PE. Absorption measurements showed that high pressure (HP) induces dissociation of R-PE into subunits followed by subunit unfolding. Contrary to temperature, HP treatment showed a significant advantage under applied conditions: the protein unfolding is partly reversible, and the R-PE colour bleaching is minimized. Based on the fluorescence quenching approach, R-PE's binding affinities for Cu2+ and Zn2+ ions were 6.27x105 and 1.71x103 M-1, respectively. Absorption and near-UV/VIS CD spectroscopy suggested conformational changes in protein chromophores upon metal ions binding. Far-UV CD spectroscopy did not reveal that metal binding affects R-PE structure. The obtained results give new insights into the stability of R-PE with a good use-value in replacement of toxic synthetic dyes, preservation of R-PE red colour in fortified food and beverages by HP processing, and as a biosensor for Cu2+ in aquatic life systems.

AB  - Abstract
Background: Although still considered a safer alternative to classical cigarettes, growing body of work points to
harmful effects of electronic cigarettes (e-cigarettes) affecting a range of cellular processes. The biological effect of
e-cigarettes needs to be investigated in more detail considering their widespread use.
Methods: In this study, we treated V79 lung fibroblasts with sub-cytotoxic concentration of e-cigarette liquids, with
and without nicotine. Mutagenicity was evaluated by HPRT assay, genotoxicity by comet assay and the effect on cel-
lular communication by metabolic cooperation assay. Additionally, comprehensive proteome analysis was performed
via high resolution, parallel accumulation serial fragmentation-PASEF mass spectrometry.
Results: E-cigarette liquid concentration used in this study showed no mutagenic or genotoxic effect, however it
negatively impacted metabolic cooperation between V79 cells. Both e-cigarette liquids induced significant depletion
in total number of proteins and impairment of mitochondrial function in treated cells. The focal adhesion proteins
were upregulated, which is in accordance with the results of metabolic cooperation assay. Increased presence of post-
translational modifications (PTMs), including carbonylation and direct oxidative modifications, was observed. Data are
available via ProteomeXchange with identifier PXD032071.
Conclusions: Our study revealed impairment of metabolic cooperation as well as significant proteome and PTMs
alterations in V79 cells treated with e-cigarette liquid warranting future studies on e-cigarettes health impact.

AB  - The COVID-19 pandemic caused by the SARS-CoV2 virus poses a global health threat with over 5 million deaths recorded. There is little understanding regarding SARS-CoV2 pathogenesis in the human airways and disease severity increases with age. Neutrophils are white blood cells found in large numbers in the airways of the lungs in severe COVID-19 patients. It is not known whether this influx of neutrophils into the airway has a protective or detrimental effect. We aim to understand the role of neutrophils during COVID-19 pathology, using an experimental infection model of the airway epithelium from the eldelry and children. To do this, we collect nasal airway cells from healthy elderly and children and grow them at air-liquid interface. Once differentiation and ciliation of these cells is reached, we infect the cells with SARS-CoV2 virus and allow neutrophils to migrate from the basolateral (blood) to the apical (air) side of the epithelium, similar to a physiological airway. Using flow cytometric analyses, we measure the expression of activation markers and the number of neutrophils that migrate across the epithelium of different ages in response to SARS-CoV2 infection. Preliminary work shows less viable neutrophils recovered from the elderly epithelium, more activated neutrophils when migrating through the elderly epithelium, as well as increased numbers of neutrophils remaining on the basolateral (blood) side of the elderly epithelium. These findings point to an inflammatory neutrophil phenotype influenced by the damaged elderly epithelium and supports the hypothesis that neutrophils are responsible for the severity of disease.

AB  - In this study, different drying methodologies (convective air, oven and microwave) of Myrtus communis L. (M. communis L.) leaves were conducted to investigate their effects on the levels of phenolic compounds, antioxidant capacity of ethanolic extracts (EEs) as well as the soybean oil oxidative stability. Drying methodology significantly influenced the extractability of phenolic compounds. Microwave drying led to an increase in the amounts of total phenols, flavonoids and proanthocyanidins followed by oven drying at 70 °C. Higher temperature of drying (100 and 120 °C) led to a significant reduction of their amounts (p < 0.05). An ultra-performance liquid chromatography method combined with high resolution mass spectroscopic detection was used to analyze the phenolic fraction of extracts. Higher amounts of the identified compounds were observed when leaves were heat treated. Furthermore, the evaluation of the antioxidant activity showed that the studied extracts possess in general high antioxidant capacities, significantly dependent on the employed drying methodology. The incorporation of the different extracts at 200 ppm in soybean oil showed that its oxidative stability was significantly improved. Extracts from leaves treated with microwave (EE_MW) and at 70 °C (EE_70) have better effect than BHT. The results of the present study suggest that microwave drying could be useful to enhance the extractability of phenolic compounds and the antioxidant capacity of M. communis L. leaf extract.

AB  - In this work, we observed the effect of grape juice (% concentrated juice/% concentrated camel milk: GJ20/80, GJ50/50) and pomegranate juice (PJ20/80, PJ40/60) fortification on camel milk (CM) protein solubility and digestibility. Proteins were dissolved in sodium phosphate buffer to 50 mg/ml and defatted prior Bradford assay of protein concentration, then analyzed by Size Exclusion-Ultra High-Performance Liquid chromatography (SE-UHPLC). The CM protein aggregation and their stability were further monitored at different pH 2.0, 4.0, and 7.5 via sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Freeze dried CM (FDCM) was the reference sample and our results showed that GJ50/50 and PJ40/60 with the highest fruit juice ratio had the lowest protein content in the supernatant, hence the decreased solubility. SE-UHPLC of supernatants showed a slight decrease in retention times of 11 kDa and 62 kDa proteins for GJ50/50 and PJ40/60 suggesting a possibility of adduct formation due to fortification leading to higher molecular weight. The simulated static in vitro gastrointestinal digestion of samples revealed that most soluble proteins were readily digested by pepsin, trypsin and chymotrypsin enzymes leading to small peptides. However, the SDS PAGE of pellets showed the partial resistance of casein and α-lactalbumin against peptic digestion.

AB  - Serological testing is important method for diagnosis of severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) infection. Nucleocapsid (N) protein is the most abundant virus derived protein and strong immunogen. We aimed to find its efficient, low-cost production, suitable for serological diagnosis. SARS-CoV-2 recombinant fragment of nucleocapsid protein (rfNP; 58–419 aa) was expressed in E. coli in soluble form, purified by immobilized metal ion affinity chromatography and strong cation exchange chromatography after which it was analyzed by Mass and CD spectrometry and characterized biochemically and immunologically. Purified rfNP has secondary structure of full-length recombinant N protein, with high percentage of disordered structure (34.2%) and of β-sheet (40.7%). rfNP was tested in immunoblot using sera of COVID-19 convalescent patients. ELISA was optimized with sera of RT-PCR confirmed positive symptomatic patients and healthy individuals. IgG detection sensitivity was 96% (47/50) and specificity 97% (67/68), while IgM detection was
slightly lower (94% and 96.5%, respectively). Cost-effective approach for soluble recombinant N protein fragment production was developed, with reliable IgG and IgM antibodies detection of SARS-CoV-2 infection.

AB  - Serological testing is important method for diagnosis of severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) infection and for assessment of immunological response after the vaccination. Nucleocapsid (N) protein is the most abundant virus protein and strong immunogen. The aim was develop efficient, low-cost production of N protein large fragment and to characterize it with bottom-up, high-resolution tandem mass spectrometry and immunologically.
SARS-CoV-2 recombinant fragment of nucleocapsid protein (rfNP; 58–419 aa) was expressed in E. coli in soluble form and purified by several chromatographic steps and was subjected to SDS-PAGE and in-gel digested with trypsin.
rfNP was tested in immunoblot using sera of COVID-19 convalescent patients. ELISA was optimized with sera of RT-PCR confirmed positive symptomatic patients and healthy individuals. IgG detection sensitivity was 96% (47/50) and specificity 97% (67/68), while IgM detection was slightly lower. Identity of rfNP was confirmed with high scores and peptide coverage above 80%. Estimation from the value of areas under ion extracted chromatographic curves is that only up to 0,03% of the total band protein quantity belongs to host proteins, while rfNP share is well above 99,9%, resulting in highly pure nucleocapsid protein preparation.

AB  - Background Mammalian meat is the most common trigger of the allergic reactions in patients with α-Gal syndrome (AGS). Milk and dairy, although less often, also cause a significant number of allergic manifestations. The aim of this study was to identify α-Gal-containing bovine milk proteins with allergenic properties among AGS patients. Methods Thirty-eight AGS patients with IgE to milk were included in the study. Milk proteins were analyzed for the presence of α-Gal and for binding by patients’ IgE using immunoblot, ImmunoCAP, and inhibition ELISA. Allergenicity of milk and milk proteins was assessed by basophil activation test. Results More than half of the AGS patients reported allergic reactions to milk or dairy products. Bovine γ-globulin (BGG), lactoferrin (LF), and lactoperoxidase (LPO) were identified as α-Gal carrying proteins which were recognized by AGS patients’ IgE. Whey mirrored the anti-α-Gal and IgE reactivity of BGG, LF, and LPO. Eighty-nine percent of the patients displayed IgE to BGG, 91% to LF, and 57% to LPO. Inhibition of α-Gal-specific IgE binding was achieved by BGG, LF, LPO, and whey. These proteins also activated AGS patients’ basophils. Interestingly, at lower concentrations, LF was the most potent inhibitor of IgE binding, and the most potent activator of basophils. Conclusion BGG, LF, and LPO were all found to be relevant milk α-Gal-containing glycoproteins that bound AGS patients’ IgE antibodies and activated their basophils. These proteins are probably involved in the allergic reactions to milk in AGS patients. LPO was for the first time shown to be an allergen.
