Contrasting results were reported by De Biasi et al. who showed that patients with COVID-19 had similar relative counts of CD4+ T cells compared to the controls (with the exception of CCR7−CD45RA+CD28−CD27+/− terminal effector Th cells that were decreased compared to the control), but the absolute number of these cells was significantly lower [38]. The gene discussed is CD4; the disease is COVID-19.
