FAF1 and infection: To examine in vivo host responses to infection by L. monocytogenes, FAF1+/+ and FAF1gt/gt mice were infected intraperitoneally with L. monocytogenes (5 × 105 CFU per mouse) and serum cytokine levels, bacterial load, and proinflammatory gene expression in the spleen and liver were measured at 24 h post-infection (hpi).
