Decreased NK cell frequency in chronic hepatitis C does not affect ex vivo cytolytic killing
Chihiro Morishima, Denise M. Paschal, Chia C. Wang, Christina S. Yoshihara, Brent L. Wood, Anthony E. T. Yeo, Scott S. Emerson, Margaret C. Shuhart, David R. Gretch – 22 February 2006 – Prior studies have suggested that natural killer (NK) cell function might be impaired in chronic hepatitis C virus (HCV) infection. Circulating NK cell frequency and cytolytic activity were examined freshly ex vivo in HCV‐infected and uninfected subjects. Surprisingly, the intrinsic cytolytic activity of peripheral blood NK‐enriched cells was similar between HCV‐infected and uninfected groups (P = .91).
