AB  - Fibrinogen is a plasma protein that is highly susceptible to oxidation. Because of this chemical modification, fibrinogen acquires thrombogenic characteristics under different pathophysiological conditions. Increased carbonyl content and reduced porosity impair the degradation of formed fibrin mediated by plasmin. Fibrinogen is capable of interacting with many proteins, ions, and small molecules. These interactions can modify the functions of this protein. The discovery of new binding partners that may protect fibrinogen from harmful oxidation and, thus, preserve its normal function is essential. Some of the newly detected interactions between fibrinogen and small, natural bioactive molecules, together with the influence of these interactions on the structure and function of fibrinogen, will be presented in this text.

AB  - The French paradox describes a lower incidence of cardiovascular problems despite a high intake of saturated fats. This phenomenon was associated with higher consumption of red wine, as it was later discovered that the presence of antioxidants, including resveratrol, have beneficial effects. We hypothesized that resveratrol may have a more direct role in protection from harmful oxidation, presumably through binding to important proteins of the blood coagulation process. Spectrofluorimetry demonstrated that resveratrol is capable of binding to fibrinogen, the main protein in the coagulation process, which is also important as a food additive. Various spectroscopic methods determined that binding does not cause fibrinogen unfolding or destabilization since protein melting temperature remains unchanged. A mutually protective effect against the free radical-induced oxidation of polyphenol and fibrinogen was found. The presence of fibrinogen caused only a negligible masking effect of the antioxidative abilities of resveratrol, measured by a reduction of hexacyanoferrate (III), while greatly increasing its solubility in an aqueous environment, thus increasing its potential bioavailability. Due to its interaction with fibrinogen, resveratrol may serve as an antioxidant at the site of injury. The antioxidative effect of resveratrol may also protect and thus keep the desired characteristics of fibrinogen during the application of this protein as a food additive.
