There is a release of inflammatory cytokines and chemokines typical of T-helper-1 (Th-1), such as IL-6, IFNγ, interferon gamma-induced protein 10 (IP-10) and the chemokine ligand 2 (CCL2), which then attracts and activates monocytes, macrophages and T cells with the aggravation of inflammation at the site of infection. This evidence concerns the gene IL6 and infection.
