Retroviral infections generate a strong activation and expansion of regulatory T cells (Tregs).In the Friend Retrovirus (FV) mouse model this induction of Tregs is dependent on the cytokines IL-2 and membrane-bound TNFa,which are produced by virus-specific effector T cells.Since it was described that retroviral infections induce several distinct populations of cytotoxic cells,e.g.
