For example, during murine CNS infections, including mouse hepatitis virus, a murine coronavirus (strains Srr7, cl-2, and A59), the Armstrong strain of lymphocytic choriomeningitis virus (LCMV), all show there is an influx into the brain and subarachnoid space of CD8+ T cells, monocytes and neutrophils into the meninges quickly after infection (Kim et al., 2009; Takatsuki et al., 2009; Cupovic et al., 2016; Watanabe et al., 2016). The gene discussed is CD8A; the disease is infection.
