Quantification of immune subpopulations revealed concomitant decreases in CD8+ T cells (2.0‐fold) and classical monocytes (1.3‐fold) in ICU, the latter of which confirms monocytopenia, specific to classical monocytes, as a hallmark of COVID‐19 infection in patients with T2D (Fig 4C). The gene discussed is CD8A; the disease is Decreased total monocyte count.
