Fig. 2: T cell subsets in individuals recovered from COVID-19.
From: Immune memory in convalescent patients with asymptomatic or mild COVID-19
Blood samples were collected from individuals recovered from COVID-19 and healthy controls, PBMC were isolated for analysis of T cell subsets. a Representative flow plots for the expression of CD45RA and CXCR5 within the CD4+ populations from healthy controls and recovered COVID-19. b Proportions of cTfh cells (CD45RA-CXCR5+) in CD4+ T cell populations from HC, RS and RA. c Representative flow plots for the expression of CXCR3 and CCR6 within the CD4+CD45RA-CXCR5-populations from healthy controls and recovered COVID-19. d Proportions of Th subsets within the CD4+CD45RA-CXCR5- populations from HC, RS, and RA. e Representative flow plots for the expression of CXCR3 and CCR6 within the cTfh populations from healthy controls and recovered COVID-19. f Proportions of cTfh subsets within the cTfh populations from HC, RS, and RA. Each symbol represents an individual throughout. RS, individuals recovered from COVID-19 with symptoms (n = 20); RA, individuals recovered from asymptomatic (n = 13); HC, healthy controls (n = 10). Data in b, d, f were analyzed using unpaired, two-sided Mann–Whitney U test. n.s., not significant.
