Hepatocyte‐derived exosomes promote T follicular regulatory cell expansion during hepatitis C virus infection
Dustin A. Cobb, Ok‐Kyung Kim, Lucy Golden‐Mason, Hugo R. Rosen, Young S. Hahn – 27 July 2017 – Hepatitis C virus (HCV) is a global health concern that can cause severe liver disease, such as cirrhosis and hepatocellular carcinoma. Control of HCV requires vigorous T‐cell responses, yet CD4+ T cells in chronic HCV patients are dysfunctional. T follicular regulatory (Tfr) cells are a subset of regulatory T cells that suppress T follicular helper (Tfh) cells and the generation of high affinity antibody‐producing B cells.
