[Cytokine regulation of immune response in patients with acute HCV-infection]
Aim:
To study the cytokine spectrum (IL-1beta, IL-2, IL-4, IL-6, TNF-alpha, interferon-alpha, interferon gamma) in patients with acute hepatitis C (AHC).
Material And Methods:
Peripheral blood from 70 AHC patients was studied for cytokines using enzyme immunoassay (kits made by Protein contur, St-Petersburg). RESULTS. A primary examination in all the patients who finally recovered detected high levels of IL-2, IL-6, interferon-gamma, normal levels of IL-4. This evidenced for marked activity of Th1-lymphocytes, depressed synthesis of Th2-mediators stimulating immune response and elimination of the virus. AHC patients who later developed chronic disease had less frequent rise of proinflammatory mediators, but more frequent high IL-4 levels. Such features of immune response reflected higher activity of Th2-lymphocytes inhibiting Th1-effector mechanisms. This promoted active virus replication and formation of chronic hepatitis C.
Conclusion:
Determination of cytokine spectrum in AHC has a prognostic implication.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
