Abstract

The SARS-CoV-2 genome encodes many proteins that directly compromise Type I interferon-mediated innate immunity. In acute COVID-19 the consequent dysregulated hyper-inflammatory state alters the milieu of draining lymph nodes and indirectly induces anatomically restricted, weeks-long transient defects in adaptive immunity. The striking attenuation of discrete aspects of T cell immunity may facilitate the evolution of more transmissible viral variants. No techniques employed to date, including single nuclear sequencing, have revealed information on pulmonary T cell subsets in severe COVID-19. Here we demonstrate an unexpected paucity of total CD8+T cells and CD8+Granzyme B+ T cells in the lung parenchyma in acute COVID-19. Apart from broadly compromising the generation of T FH cells in draining lymph nodes, acute COVID-19 is also linked to attenuated CD8+ T cell activation and infiltration of the lungs, and the delayed pulmonary accumulation of CD4+T cells with a cytotoxic phenotype.
