Compared to controls and to COVID-19 specimens that were negative for virus in WAT, virus-positive specimens showed significantly increased numbers of cells expressing CD45 pan-leukocyte marker (p < 0.01) (Fig. 1D), CD3 T-cells (p < 0.05) (Fig. 1E), CD57 natural killer cells (p < 0.05) (Fig. 1F), and CD68 macrophages (p < 0.05) (Fig. 1G) (Fig. 2). This evidence concerns the gene B3GAT1 and COVID-19.
