Similarly, levels of innate IR cytokines (IL6, IP10, IL8, IL1RA, MIG, IL1a, GROa, sRAGE, STNFRI, IL15, MCP1, sTNFRII, IL1b, TNFa, sIL1RI, sIL1RII, RANTES, MCP3, EOTAXIN, IL12p40, sIL6R, MIC1b and MIC1a) were significantly higher (p < 0.01) in the patients than in controls (Figure 1B) and those of the molecules GMCSF, GCSF, MSCF, IL2, IL7, sVEGFR1, EGF, VEGFA, sVEGFR3, FLT3L, PDGFAA, FGF2, sVEGFR2 (all p < 0.01) and PDGFABBB and sEGFR (both p < 0.05) were also significantly higher in the COVID-19 patients. Here, IL15 is linked to COVID-19.
