Studies have been shown that African American people were more likely than white ones to carry allelic variants that increase the expression of the pro-inflammatory cytokines, such as IL-1Α, IL-1Β, IL-6, TNF-α, and IL-18, and less likely to carry allelic variants known to increase expression of IL-10, which could account to their resistance profile to infections [32]. Here, IL6 is linked to infection.
