IL6 and infection: Thus, to determine whether IL‐6‐induced CD11b+Ly6ChiLy6G– proinflammatory monocytes inhibit T cell function and protective immunity, we isolated CD11b+Ly6ChiLy6G– cells at day five post N67C infection in WT mice, and then co‐cultured them with CFSE‐labeled naïve CD3+ T cells from splenocytes (Figure S6G, Supporting Information).
