CCL3 and COVID-19: Interestingly, in our cohort CXCL10 performed as well, or better, as a panel including 6 additional inflammatory cytokines (IL6, CXCL8, CCL2, CCL3, IL10, and TNFα), suggesting that these other cytokines do not add predictive value to CXCL10 alone with regard to inflammatory response to COVID19.
