Figure 2. — The frequencies of innate immune cells in COVID-19 and control subjects. The percentages of CD56^low CD16⁺ NK cells, CD56^high CD16^+/− NK cells, and monocytes were studied by flow cytometry (a and b) and then analyzed (c–e). The results are representative of 57 independent experiments for COVID-19 patients at the first day of treatment, 51 independent experiments for COVID-19 patients in 10 days of treatment, and 40 independent experiments for healthy individuals. Each bar in (c–e) shows mean ± SEM.
