A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

The cellular immune response to hepatitis C virus (HCV) plays a critical role in determining the clearance or persistence of HCV. Moreover, in chronic HCV infection, these responses that are insufficient to eradicate virus completely may cause liver injury. In this study, the memory T cells responses specific to the core protein were measured by interferon-gamma Elispot assay after in vitro stimulation of peripheral blood mononuclear lymphocytes from chronically infected subjects. Ten out of the 22 patients studied (45%) present a core-specific response with a preferential recognition of the N-terminal and central parts. There was no relationship between T cell responses and the parameters of disease evolution as determined by ALT (serum alanine transaminase levels), and histologic hepatic damage (Metavir score A and F), but there was a positive relationship between the presence of a core-specific T cell responses and the viraemia.
