The Gil-Mansos group recently conducted a comprehensive FACS analysis comparing a control vs COVID-19 disease group (n = 51) within recovered COVID-19 individuals to demonstrate a significant cell cluster at 10 months after recovery of CD4+ CD45RA− CCR4− CCR10− CD27+ CCR6−CXCR3+ CD127+ cells. The gene discussed is CD4; the disease is COVID-19.
