As previously described [28], infection progress correlated with the expression of pro-inflammatory cytokines, such as chemokine (C–C motif) ligand 2 (Ccl2), also referred to as monocyte chemoattractant protein 1 (MCP1), and C-X-C motif chemokine ligand 10 (Cxcl10), also known as Interferon gamma-induced protein 10 (IP-10), in both brain and cerebellum (Figure 1D,E). This evidence concerns the gene CCL2 and infection.
