CCL2 and infection: In BAL fluid infection with either SVV BAC or WT SVV induced production of several key chemokines, including MCP-1 (recruits monocytes, memory T cells, DCs [14]), MDC (recruits monocytes, monocyte-derived DCs, and NK cells [15]), MIF (inflammatory and atherogenic leukocyte recruitment [16]), MIG (recruits T cells [17]), MIP-1α (recruits and activates polymorphonuclear leukocytes [18]), MIP-1β (recruits NK cells and monocytes [18]), I-TAC (recruits T cells [19]), and eotaxin (recruits eosinophils [20]) (Figure 3).
