SERPING1 and COVID-19: Consistently, proteomic and metabolomics data from CMs revealed several genes (KNG1, TXNIP, ITIH4, TIMP1, SERPING1/2/3, ITGA1, ADAR, and CLIC5 etc.)and molecules (adenosine and inosine) were related with platelet activation, thus, adding antiplatelet might be a possible therapeutic for COVID-19.
