Abstract:
A peptide-based enzyme immunoassay (PBEIA) has been developed using synthetic peptides whose sequences were selected from the core, envelope and non-structural regions of the prototype hepatitis C virus (HCV) genome. Results of PBEIA of sera obtained from several patients with various liver disorders were compared to those of commercial enzyme-linked immunosorbent assays (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). A large number of samples, which were repeatedly negative in commercial ELISA, were positive in PBEIA. There was a good correlation between the results of PBEIA and RT-PCR. The developed PBEIA proved to be a sensitive assay that had high specificity and was capable of detecting antibodies in various HCV-related liver disorders including the acute phase of the infection.

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...
