Interactions between proteins altered in serum and CACs samples. A Venn’s diagram including the number of proteins up- or down-regulated, common or exclusive in serum samples and CACs + PCR vs CACs + Neg and CACs + IgG vs CACs + Neg comparisons. B An in-silico analysis evaluating the potential interactions between altered proteins in the serum of COVID-19 asymptomatic donors (PCR + and IgG +) and the proteins altered in healthy CACs in response to those serums was performed with PINA v3 on-line platform. C One of the most representative functions found between the interactions found between both sets (serum and CACs) of altered proteins was platelet activation, including platelet aggregation and degranulation.
