“…We observed kinetics of various cytokines that are reportedly increased in patients with MIS-C, including IL-1Ra ( 14 , 21 ), IL-1β ( 19 ), IL-6 ( 15 – 20 , 22 ), IL-8 ( 18 , 19 ), IL-10 ( 16 , 20 ), IL-17 ( 17 ), IL-18 ( 20 ), CXCL10 ( 15 , 17 , 21 , 22 ), tumor necrosis factor-α ( 18 , 19 ), interferon-γ ( 20 , 21 ), CCL3 ( 17 ), CCL20 ( 17 ), CCL19 ( 17 ), CCL2 ( 21 , 22 ), CXCL1 ( 17 ), and CXCL11 ( 17 ). We found five patterns in the cytokine kinetics in contrast with patient's symptoms.…”
