AB  - In this study, a cost-effective sandwich ELISA test, based on polyclonal antibodies, for routine quantification SARS-CoV-2 nucleocapsid (N) protein was developed. The recombinant N protein was produced and used for the production of mice and rabbit antisera. Polyclonal N protein-specific antibodies served as capture and detection antibodies. The prototype ELISA has LOD 0.93 ng/mL and LOQ 5.3 ng/mL, with a linear range of 1.52–48.83 ng/mL. N protein heat pretreatment (56 °C, 1 h) decreased, while pretreatment with 1% Triton X-100 increased analytical ELISA sensitivity. The diagnostic specificity of ELISA was 100% (95% CI, 91.19–100.00%) and sensitivity was 52.94% (95% CI, 35.13–70.22%) compared to rtRT-PCR (Ct < 40). Profoundly higher sensitivity was obtained using patient samples mostly containing Wuhan-similar variants (Wuhan, alpha, and delta), 62.50% (95% CI, 40.59 to 81.20%), in comparison to samples mostly containing Wuhan-distant variants (Omicron) 30.00% (6.67–65.25%). The developed product has relatively high diagnostic sensitivity in relation to its analytical sensitivity due to the usage of polyclonal antibodies from two species, providing a wide repertoire of antibodies against multiple N protein epitopes. Moreover, the fast, simple, and inexpensive production of polyclonal antibodies, as the most expensive assay components, would result in affordable antigen tests.

AB  - The SARS-CoV-2 nucleocapsid (N) protein plays a significant role in the coronavirus life cycle and participates in a variety of critical events following viral invasion1. In infected patients, high titers of immunoglobulin G (IgG) targeting N protein were detected and correlated with the clinical course of the disease2. Therefore, N protein and anti-N protein IgGs were recognized as important diagnostic indicators of COVID-19 infection in serological and quick antigen tests3. In this study, we optimized the expression of the recombinant form of SARS-CoV-2 N protein in a mammalian cell line HEK293T by comparing the transfection efficiency between Polyethylenimine (PEI) and Calcium Phosphate (CaP) DNA-complexing agents. Transfection potency was tested at different cell confluency and passage number, in several cell culture media, pre-transfection and post-transfection media change and in conditions of reduced serum. Chloroquine and glycerol treatments were included to enhance transfection efficiency as they might inhibit DNA degradation in lysosomes or increase membrane permeability. Protein expression was monitored in cell supernatants up to 7 days post-transfection in dot-bot and Western blot using anti-N protein antibodies. Both transfection methods have shown moderate to relatively high transfection efficiency dependent on the applied conditions, making them affordable and easy to use techniques for recombinant N protein production on a small-scale in adherent mammalian systems. PEI acts as a good delivery system regardless of the presence of the fetal bovine serum (FBS), while CaP transfection is more dependent on the presence of FBS which in turn favors N protein degradation. However, we have optimized both methods to achieve optimal expression of unfragmented N-protein in serum-free conditions. Apart from setting up a cost-effective platform for expression of N protein in mammalian cells, we plan on investigating the mechanisms behind the PEI and CaP non-viral gene delivery systems as there are still some uncertainties in the scientific community.

AB  - Нови корона вирус (SARS CoV-2) који се појавио у Вухану 2019. године припада групи једноланчаних РНК вируса [1]. Представља нови инфективни агенс за хуману популацију и веома је брзо детектован у великом броју земаља. Узрочник је респираторних инфекција које могу да буду праћене и веома тешком клиничком сликом. Брзо ширење, одсуство имунитета на овај вирус и одсуство поузданих тестова за детекцију вируса у тренутку избијања пандемије су болест изазвану овим вирусом брзо претворили у здравствени и друштвени проблем највишег приоритета на глобалном нивоу. Иако су највеће биотехнолошке компаније убрзано почеле са развојем и масовном производњом дијагностичких тестова и вакцина, њихова доступност у тренуцима највеће потражње је и даље недовољна, а цене истих су лимитирајући фактор за бољу контролу болести и ширења пандемије [2]. Развој сопствених и одржива производња тестова и вакцина за COVID-19 су од великог друштвеног значаја. Важан предуслов за одрживу производњу тестова је доступност рекомбинантних антигена вируса и могућност производње истих на великој скали за потребе производње домаћих тестова. Овим техничким решењем се описује добијање два кључна антигена новог корона вируса рекомбинантном технологијом и њихова примена у серолошком ЕЛИСА тесту који производи Институт за примену нуклеарне енергије, ИНЕП, као и за добијање реагенаса за детекцију антигена новог корона вируса (специфичних антитела). У првој фази, оптимизоване су секвенце протеина које су подигле осетљивост постојећих серолошких тестова. Иновативност нашег приступа се огледа и у разрађеним експерименталним протоколима за добијање рекомбинантних протеина нуклеокапсида на великој скали, као и у солубилној форми, што олакшава поступак пречишћавања. Избор фрагмента нуклеокапсида који се хетеролого експримира у солубилној форми, а специфично детектује антитела и генерише јак имуни одговор током имунизације животиња (имуногеност) на основу прегледа познатих епитопских секвенци је кључна иновација овог техничког решења. Ово је први пример успешно примењеног рекомбинатног протеина произведеног у Србији у дијагностичком тесту који је регистрован
код Агенције за лекове и медицинска средства Републике Србије (број решења 515-02-02370-21-002), а који је примену нашао и на међународном нивоу.

AB  - RT-PCR remains the primary method of diagnosing SARS-CoV-2. Serological diagnosis of COVID-19 is simple and does not require complex techniques and equipment, rendering it suitable for rapid detection and massive screening. However, serological tests cannot confirm SARS-CoV-2, and results will be false negative when antibody concentrations fall below detection limit. Serological testing is important method for diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) infection. Antigen-based tests show high specificity, but sensitivity is relatively low. For development and further improvement of both serological and antigen-based tests, availability of recombinantly producted SARS CoV-2 antigens is needed and during the periods of high demend in the pandemic, it was a limited factor both for research and diagnostic tests production by national producers of tests. Nucleocapsid (N) protein is the most abundant virus derived protein and strong immunogen. We aimed to find its efficient, low-cost production. SARS-CoV-2 recombinant fragment of nucleocapsid protein (rfNP; 58-419 aa) was expressed in E. coli in soluble form, purified 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 beta-sheet (40.7%). rfNP was tested in immunoblot using sera of COVID-19 convalescent patients. Cost-effective approach for soluble recombinant N protein fragment production was developed, with reliable IgG and IgM antibodies detection of SARS-CoV-2 infection. 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). Application of serological ELISA for seropositivity detection in 200 allergic children in comparison to non-allergic did not show a bias towards any of the tested groups.  Furthermore, we have optimized production of rfNP at a large scale to raise specific antibodies to N-protein in rabbit and mice and develop an in house ELISA for quantification of N protein in biological fluids. Test was clinically validated in 200 PCR positive patients and showed a sensitivity of around 50%.

AB  - The accurate diagnosis of people with suspected infection with the SARS-CoV-2 is
essential to curb the global spread of COVID-19. The presence of SARS-CoV-2 can be
detected by RT-PCR (it detects RNA of the virus) or by the presence of viral antigens in
biological fluids in ELISA or similar techniques using antibodies developed in animals.
The aim of the study was the establishment of a quantitative polyclonal sera-based test for
routine measurement of the concentration of SARS CoV-2 nucleocapsid protein using
absorbance measurement in a standard 96-well microtiter plate. For the purposes of the test
development, recombinant N protein was produced and used for the production of mice
and rabbit antisera. Produced antisera were purified and titer was determined. High-affinity
polyclonal N-protein specific antisera were used for N-protein specific ELISA test
development. The test is based on mice polyclonal sera adhered to microtiter plate bottom
for the capture of the N protein from the specimen. Various concentrations of the
recombinant N-protein were used to generate a standard curve for protein quantification.
The N-protein bound to the mice antibodies was detected with rabbit polyclonal sera and
anti-rabbit antibody coupled to an enzyme that provides spectrophotometric measurement.
We have successfully developed the prototype ELISA for the quantification of N-protein
with the detection limit being in the range of ng/mL. The average LOD value for the
prototype ELISA was determined to be 9.2 ng/mL, while the average LOQ value was
10.2 ng/mL. We have demonstrated that produced polyclonal antisera are suitable for the
detection of N-protein with affinity and specificity similar to, or better than commercial
antibodies. Furthermore, the prototype ELISA can be used with satisfactory confidence for
quantification of the N-protein in protein-rich samples, similar to human sera.

AB  - Allergen-specific immunotherapy (AIT) is a desensitizing treatment for allergic diseases that corrects the underlined pathological immune response to innocuous protein antigens, called allergens. Recombinant allergens employed in the AIT allowed the production of well-defined formulations that possessed consistent quality but were often less efficient than natural allergen extracts. Combining recombinant allergens with an adjuvant or immunomodulatory agent could improve AIT efficacy. This study aimed to perform structural and functional characterization of newly designed recombinant chimera composed of the Bet v 1, the major birch pollen allergen, and Banana Lectin (BanLec), TLR2, and CD14 binding protein, for the application in AIT. rBet v 1-BanLec chimera was designed in silico and expressed as a soluble fraction in Escherichia coli. Purified rBet v 1-BanLec (33.4 kDa) retained BanLec-associated biological activity of carbohydrate-binding and preserved IgE reactive epitopes of Bet v 1. The chimera revealed secondary structures with predominant β sheets. The immunomodulatory capacity of rBet v 1-BanLec tested on macrophages showed changes in myeloperoxidase activity, reduced NO production, and significant alterations in the production of cytokines when compared to both rBanLec and rBet v 1. Comparing to rBet v 1, rBet v 1-BanLec was demonstrated to be more efficient promoter of IL-10 production as well as weaker inducer of NO production and secretion of pro-inflammatory cytokines TNFα, and IL-6. The ability of rBet v 1-BanLec to promote IL-10 in together with the preserved 3D structure of Bet v 1 part implies that the construct might exert a beneficial effect in the allergen-specific immunotherapy.

This study aimed to perform structural and functional characterization of newly designed recombinant chimera composed of the Bet v 1, the major birch pollen allergen, and Banana Lectin (BanLec), TLR2, and CD14 binding protein, for the application in AIT. rBet v 1-BanLec chimera was designed in silico and expressed as a soluble fraction in Escherichia coli. Purified rBet v 1-BanLec (33.4 kDa) retained BanLec-associated biological activity of carbohydrate-binding and preserved IgE reactive epitopes of Bet v 1. The chimera revealed secondary structures with predominant β sheets. The immunomodulatory capacity of rBet v 1-BanLec tested on macrophages showed changes in myeloperoxidase activity, reduced NO production, and significant alterations in the production of cytokines when compared to both rBanLec and rBet v 1. Comparing to rBet v 1, rBet v 1-BanLec was demonstrated to be more efficient promoter of IL-10 production as well as weaker inducer of NO production and secretion of pro-inflammatory cytokines TNFα, and IL-6. The ability of rBet v 1-BanLec to promote IL-10 in together with the preserved 3D structure of Bet v 1 part implies that the construct might exert a beneficial effect in the allergen-specific immunotherapy.",

AB  - Vaccines can have heterologous effects on the immune system, i.e., effects other than triggering an immune response against the disease targeted by the vaccine. We investigated whether monoclonal antibodies (mAbs) specific for tetanus could cross-react with Chlamydia and confer heterologous protection against chlamydial infection. The capability of two tetanus-specific mAbs, namely mAb26 and mAb51, to prevent chlamydial infection has been assessed: (i) in vitro, by performing a neutralization assay using human conjunctival epithelial (HCjE) cells infected with Chlamydia trachomatis serovar B, and (ii) in vivo, by using a guinea pig model of Chlamydiacaviae-induced inclusion conjunctivitis. The mAb26 has been superior in comparison with mAb51 in the prevention of chlamydial infection in HCjE cells. The mAb26 has conferred ≈40% inhibition of the infection, compared to less than 5% inhibition in the presence of the mAb51. In vivo, mAb26 significantly diminished ocular pathology intensity in guinea pigs infected with C. caviae compared to either the mAb51-treated or sham-treated guinea pigs. Our data provide insights that tetanus immunization generates antibodies which induce heterologous chlamydial immunity and promote protection beyond the intended target pathogen.

AB  - We demonstrated that a recombinant banana lectin (rBanLec), which structural characteristics and physiological impacts highly resemble those reported for its natural counterparts, binds murine peritoneal macrophages and specifically modulates their functional characteristics. By using rBanLec in concentrations ranging from 1 mu g to 10 mu g to stimulate resident (RMs) and thioglycollate-elicited (TGMs) peritoneal macrophages from BALB/c and C57BL/6 mice, we have shown that effects of rBanLec stimulation depend on its concentration but also on the functional status of macrophages and their genetic background. rBanLec, in a positive dose-dependent manner, promotes the proliferation of TGMs from both BALB/c and C57BL/6 mice, while its mitogenic influence on RMs is significantly lower (BALB/c mice) or not detectable (C57BL/6 mice). In all peritoneal macrophages, irrespective of their type and genetic background, rBanLec, in a positive dose dependent manner, enhances the secretion of IL-10. rBanLec stimulation of RMs from both BALB/c and C57BL/6 resulted in a positive dose-dependent promotion of proinflammatory phenotype (enhancement of NO production and IL-12 and TNF alpha secretion, reduction of arginase activity). Positive dose-dependent skewing toward proinflammatory phenotype was also observed in TGMs from C57BL/6 mice. However, the enhancement of rBanLec stimulation promotes skewing of TGMs from BALB/c mice towards anti-inflammatory profile (reduction of NO production and IL-12 secretion, enhancement of arginase activity and TGF alpha and IL-4 secretion). Moreover, we established that rBanLec binds oligosaccharide structures of TLR2 and CD14 and that blocking of signaling via these receptors significantly impairs the production of TNFa and NO in BALB/c macrophages. Since the outcome of rBanLec stimulation depends on rBanLec concentration as well as on the functional characteristics of its target cells and their genetic background, further studies are needed to investigate its effects under physiological and specific pathological conditions.

In order to achieve more efficient treatment, lately there is an effort to find new substances, such as certain biomaterials, that are non-toxic to humans with antibiotic potential. Lignins and lignin-derived compounds have been proposed to be good candidates for use in medicine and health maintenance. In this study, the antibacterial activity of the lignin model polymer dehydrogenate polymer (DHP) in alginate hydrogel (Alg) was studied. The obtained results show that DHP-Alg has strong antimicrobial activity against several bacterial strains and biofilms and does not have a toxic effect on human epithelial cells.

AB  - Recombinant banana lectin isoform (rBanLec) attaches specifically to the mucosal surface, crosses the epithelial barrier and then directly affects the immune response in mouse colon. Structural characteristics, specificity and physiological impacts of rBanLec reported until now highly resemble those of its natural counterpart. Here, we demonstrated that a dose dependent stimulation of the colon with rBanLec skewed the immune response towards Th1/Th17 direction and this effect was counterbalanced by the rise in IL-10 production. Qualitative and quantitative characteristics of the established cytokine network were dependent on the applied rBanLec concentration. In addition, rBanLec enhanced local NO production and myeloperoxidase activity and promoted an increase in local IgA and IgG production. Stimulation with rBanLec can be beneficial in prevention of pathologies raised due to inappropriate cell-mediated immune response as well as in prevention of the pathogen invasion via the colon.

AB  - To explore the potential usage of recombinant banana lectin as an immunostimulator it was of interest to analyze the effect it exerted in vivo in mice, upon two different routes of exposure. By Western blotting analysis of the gastric and intestinal luminal content it was found that recombinant banana lectin is stable in vivo in the mouse digestive tract, where it specifically interacts with the mucosal surfaces which can be inhibited by the addition of glucose. Its attachment to mice jejunum has been confirmed by immunofluorescence. In addition, it was able to induce systemic immunity, evidenced by specific antibody production, by oral application, a property that might be exploited for the induction of systemic immune responses.

AB  - Lectins are widely used in many types of assay but some lectins such as banana lectin (BanLec) are recognised as potent immunostimulators Although BanLec's structure and binding characteristics are now familiar, its immunostimulatory potential has not yet been fully explored The synthesis by recombinant technology of a BanLec isoform (rBanLec) whose binding properties are similar to its natural counterpart has made it possible to overcome the twin problems of natural BanLec's microheterogeneity and low availability This study's aim is to explore the immunostimulatory potential of rBanLec in the murine model Analyses of the responses of Balb/c- and C57 BL/6-originated splenocytes to in vitro rBanLec stimulation were performed to examine the dependency of rBanLec's immunostimulatory potential upon the splenocytes' genetic background It is shown that the responses of Balb/c- and C57 BL/6-originated splenocytes to rBanLec stimulation differ both qualitatively and in intensity. The hallmarks of the induced responses are T lymphocyte proliferation and intensive interferon-gamma secretion Both phenomena are more marked in Balb/c-originated cultures; Balb/c-originated lymphocytes produce interleukin (IL)-4 and IL-10 following rBanLec stimulation Out results demonstrate that any responses to rBanLec stimulation are highly dependent upon genetic background. they suggest that genetic background must be an important consideration in any further investigations using animal models or when exploring rBanLec's potential human applications (C) 2009 Elsevier B V.

AB  - Aims: This study focuses on the isolation and characterization of a peptide with bacteriocin-like properties isolated from Lactobacillus rhamnosus strain 68, previously identified by 16S rRNA gene sequencing and originating from human gastrointestinal flora. Methods and Results: The peptide was isolated from a supernatant of bacteria maintained under restrictive conditions by a combination of ethanol precipitation and reversed-phase chromatography. The molecular mass of the peptide as assessed by mass spectrometry was 6433 center dot 8 Da. An isoelectric point of 9 center dot 8 was determined by 2D-PAGE. The peptide designated rhamnosin A inhibited Micrococcus lysodeikticus ATCC 4698 but did not inhibit Lactobacillus plantarum 8014 or Lact. plantarum 39268. Inhibitory activity against M. lysodeikticus at concentrations used in this study was shown to be bacteriostatic rather than bacteriolytic or bactericidal. Rhamnosin A retained biological activity after heat treatment (95 degrees C, 30 min) but was sensitive to proteolytic activity of pepsin and trypsin. Conclusions: The N-terminal sequence of rhamnosin A, as determined by Edman degradation and in more detail by blast analysis, did not show identity with any currently available Lact. rhamnosus HN001-translated protein sequences, nor any significant similarity with other sequences in the nonredundant protein sequence database. Being a small, heat-stable, nonlanthionine-containing peptide, rhamnosin A should be categorized as a class II bacteriocin. Significance and Impact of the Study: This study describes a partial bacteriocin sequence isolated from Lact. rhamnosus 68 and broadens our understanding of bacteriocins.

AB  - Thaumatin-like proteins (TLPs) have been established as a new family of fruit and pollen allergens. The aim of this study was to develop a two-site ELISA for the quantification of the thaumatin-like kiwi allergen (Act d 2) in kiwifruit extracts and kiwi fruit-containing food products. Genomic DNA (gDNA) of Act d 2 was amplified and the deduced amino acid sequence was determined to obtain a primary structure. Act d 2 purified from kiwifruit extract by HPLC was identified by Edman degradation and MS. Balb/c mice were immunized with Act d 2 for the production of mAbs by hybridoma technology. The optimized ELISA measured Act d 2 concentrations ranging from 0.2 to 9.0 ng/mL, with intra- and interassay coefficients of variation of 3.65 and 10.44%, respectively. The developed ELISA is a useful method for the quantification of the thaumatin-like kiwi allergen in kiwifruit extracts as well as the allergen level in kiwifruit-containing food products. It may be a helpful analytical tool for the evaluation of the stability (integrity) of fruit allergen extracts for in vitro diagnosis.
