Specifically, increased levels of various chemokines [C-X-C motif chemokine 1 (CXCL1), CXCL5, CXCL6, CXCL11] and cytokines [interleukin-17A (IL-17A), cluster of differentiation 40 (CD40), IL-6] were observed in the MIS-C group compared to the pediatric COVID-19 group (Table 3) [43]. Here, CXCL1 is linked to COVID-19.
