As demonstrated in Table 4, PD1, TIM3, and LAG3 expression was significantly increased in all cell subsets of COVID-19 patients when compared with healthy controls, except for TIM3+CD4+CD3+CD45+ (p = 0.64), TIM3+CD8+CD3+CD45+ (p = 0.41), and TIM3+CD39+CD8+CD3+CD45+ (p = 0.060). The gene discussed is CD4; the disease is COVID-19.
