CD8A and infection: As it was not clear whether this early suppression is exerted by the MCK2 chemokine attracting immune-regulatory cells suppressing the T cell response [25] or by gHgLMCK2-dependent infection and subsequent reprogramming of T cell-activating cells, such as macrophages and dendritic cells [33,34], we compared the IE1-specific CD8+ T cell response at day 4 p.i. for wt and all three MCMV mutants.
