Figure 3. Covid-19 with mild self-limited GI disease (A, Early effective Innate immune response mediated by NK cells, dendritic cells, macrophages, and other cells cause early resolution of GI infection. Type I interferon-mediated cytokine response plays a crucial role in this phase. B, Adaptive immune response- Specific adaptive immune response mediated by Th1/Th17 cells, CD8 T cells, plasma cells, B cells, and other cells cause the culmination of viral clearance. C, Intestinal immunity- GI mucosal secretory IgA can entrap viruses and reduce docking and entry of the virus into cells. Intestinal microbiota and COVID-19 virus interaction may have a role in combating GI infection.)
