A complete diagnostic autopsy is the gold-standard to gain insight into Coronavirus disease 2019 (COVID-19) pathogenesis. To delineate the in situ immune responses to SARS-CoV-2 viral infection, we performed comprehensive high-dimensional immune profiling in 22 COVID-19 decedents from Wuhan, China. We first identified TIM-3- and PD-1-mediated immunosuppression as a hallmark of severe COVID-19, particularly in men. Next, we observed that PD-1+ cells were proximal rather than distal to TIM-3+ cells and that lymphocytes were distal rather than proximal to SARS-CoV-2 viral antigens. Additionally, activated myeloid cells were found in close proximity to SARS-CoV-2 viral antigens. Indeed, most infected cells across multiple organs were myeloid cells. We subsequently demonstrated a positive correlation between viral load and immunosuppression and dendritic cell markers. SARS-CoV-2 viral infection induces lymphocyte suppression yet myeloid activation in severe COVID-19. We should thus consider the two immune compartments separately when investigating disease progression |
