In a previous study using IVM imaging to explore Lm infection foci that form in subcapsular DCs (scDCs) of the splenic RP following primary infection (day 5 after infection), Lm-specific effector CD8+ T cells were shown to migrate to sites of infection where a mixture of myelomonocytic cells (MMCs), which include CCR2+Ly6C+ monocytes and neutrophils, accumulates (39). This evidence concerns the gene CD8A and infection.
