In contrast, there was a striking expression of the Th1-related chemokine receptor CCR5 in the ileum and liver of infected mice, as well as the chemokine ligands for this receptor CCL3 (MIP-1α), CCL4 (MIP-1β) and CCL5 (RANTES) at 8 days post infection (Figure 1A). The gene discussed is CCL5; the disease is infection.
