Sequence similarity between human immunodeficiency virus type 1 envelope protein (gp120) and human proteins: a new hypothesis on protective antibody production.

abstract：:CD8+CD28- regulatory T cells (Tregs) play important roles in chronic viral infections. Programmed death 1 (PD-1) is highly expressed on hepatitis C virus (HCV)-specific CTLs. However, little is known regarding the role of CD8+CD28-PD1+ T cells in hepatitis C. Herein, we found that the frequency of CD8+CD28-PD1+, but n...
