In contrast, an increase of naïve CD4+ T cells (p-value 1.92x10-03), M0 macrophages (p-value 1.20x10-02), M2 macrophages (p-value 1.48x10-02), naïve B cells (p-value 1.57x10-02) and naïve cytotoxic CD8+ T cells (p-value 2.31x10-02), were identified in patients who went on to survive COVID-19 indicative of an adaptive immune response (Figure 2B and Supplementary Figure 7B). The gene discussed is CD4; the disease is COVID-19.
