MAPK11 and infection: Although various MAPK genes known for regulating the activation of inflammatory cytokines and apoptotic signals were upregulated in both mouse strains, expression of genes encoding key regulators MAPK11/p38 MAPK-β (Mapk11) and MAP3K5/ASK1 (Map3k5) was not increased after infection in BALB/c, further supporting the occurrence of an intermediate M2-like profile in this strain.
