We evaluated TLR2/1L-induced innate immune cytokines e.g. TNF-α, IL-1β, IL-6, IL-23 and IL-12, known to be critical players in the control of Mtb infection, and chemokines such as Gro-α and IL-8 that are required for cell recruitment to the site of infection [31]. This evidence concerns the gene CXCL8 and infection.
