CD8A and COVID-19: Here we have performed a prospective multiparametric study of the immune response in blood from 86 COVID19 patients collected at hospital admission and compared with 40 healthy donors and 27 patients with other respiratory infections, focusing in some of the main cells involved in viral immunity (monocytes, CD8+T and NK cells) and in different families of soluble factors regulating their function (cytokines, chemokines, granzymes/Gzms and soluble NK cell ligands).
