T cell mediated immunity in virus infection

Subpopulations of T cells have many different functions which are important for the regulation of immune responses, and as effector cells to rid the host of intracellular virus infections. In this short report, we describe a few features of T cells: their viral recognition patterns, the genetics of antiviral T cell responses, and the variation in the function of T cell subpopulations in different virus infections. Our particular emphasis relates to influenza, which is one of the best analysed model systems to date.
