CD8 T cell dysfunction during chronic viral infection

Curr Opin Immunol. 2007 Aug;19(4):408-15. doi: 10.1016/j.coi.2007.06.004. Epub 2007 Jul 25.

Abstract

Clearance of primary infection often leads to the development of highly functional memory T cells capable of rapid and long-lasting protective immunity. By contrast, chronic infections can result in T cell dysfunction and poor pathogen control. In this review, we will discuss recent work that highlights two main types of T cell dysfunction during chronic infection: exhaustion of effector functions and altered memory T cell development.
