IL5 and infection: Next, pDCs sorted from Mtb-infected mice at 28 days post-infection directly induced the proliferation of CD4+ and CD8+ T cells (white bars in Fig 7B) and the production of IFN-γ and IL-2 in CD8+ T cells (white bars in Fig 7E), but there were no significant changes in IFN-γ, IL-2, IL-5 and IL-17A secretion from CD4+ T cells (white bars in Fig 7D).
