MMP-7, TGF-β, CCL2, CCL-3, CXCL-10, G-CSF, IFN gamma, IL-10, IL-2, IL-4, IL-6, IL-7, TNF-α, IL-6, and IGF-1 were studied for their correlation to the cytokine storm (as defined by Caricchio, R et al. [15]) and to higher 4-C scores (as detailed by Knight, S.R et al. [16]) in the COVID-19 patient group. Here, CSF3 is linked to COVID-19.
