IL1A and infection: Increased levels of IL-1Ra, a receptor antagonist released to mitigate the pro-inflammatory effect of IL-1, concomitant with low serum values of different pro-inflammatory cytokines (IL-1α, IL-1β, IL-2, IL-6, IL-18, CXCL8) correlated with reduced mortality after infection with moderately virulent ASFV isolates [17,18,24].
