Immune Cell in Blood may Increase Severe COVID-19 Risk by Angela Mohan on January 29, 2021 at 3:01 PM
Journal of Clinical Investigation. Our results help increase the understanding of what causes severe COVID-19 and is an important piece of the puzzle in understanding the connection between the early, innate immune system, which includes M-MDSC, and the later, adaptive immune system, which includes T cells, said researcher Anna Smed Sorensen from Karolinska Institutet.
T cells are part of the immune system and play an important part in the body s protection against viral infections such as COVID-19. M-MDSCs have been shown to increase in other inflammatory conditions, and their suppressive effect on T cell activity has been established.
