CCL2 and HIV infectious disease: CCL2 drives the T helper 2 (Th2) immune response.[65] This chemokine regulates immune cell movement to the site of HIV infection and cell activation; therefore, they are associated with HIV disease progression.[66] Within the CCL2 gene, the H7 haplotype (CCL2‐CCL7‐CCL11) has been found to reduce HIV susceptibility.[67] The H7 haplotype was significantly elevated (p  = 0.005–0.01) in uninfected exposed European‐Americans.[68] We suggest that genetic variations in haplotype 7 influence the risk of HIV‐1 infection.
