Nevertheless, an increased number of CCR6+ cells was noticed in ‘naïve’ and TEMRA CD8+ T cell subsets from COVID-19 convalescents compared to healthy controls (1.76% (1.26; 2.96) vs. 1.16% (0.69; 1.89) and 11.40% (3.27; 20.37) vs. 4.99% (1.39; 10.15), respectively, p < 0.001 in both cases). This evidence concerns the gene CD8A and COVID-19.
