Figure 4

Memory phenotypes of antigen‐specific AIM+ CD4+ and CD8+ T cells in convalescent SARS‐CoV‐2‐infected children and adults. TEMRA, TEM, and TCM of the antigen‐specific AIM+ CD4+ and CD8+ T cells from the convalescent SARS‐CoV‐2‐infected subjects were enumerated 24 h after the stimulation. Each symbol shows the percentage of TEMRA (left panels), TEM (middle panels), and TCM (right panels) in the AIM+ CD4+ or CD8+ T‐cell populations. Red circles: subjects responding to both CD4 and CD8 epitopes (#21, 23–27); gray circle: subjects responding to only CD8 epitopes (#22). Symbol represents the data derived from each individual subject. Seven subjects were studied in four independent experiments (one to three subjects/experiment depending upon enrollment). Medians were calculated and reported in the figure. TEMRA were more numerous in antigen‐specific, AIM+ CD8+ T cells than in CD4+ T cells. TEM and TCM were more numerous in antigen‐specific, AIM+ CD4+ T cells than CD8+ T cells.
