A study finds why a Covid infection causes deadly inflammation in some people

Washington: Scientists have uncovered a new mechanism that could help explain why some Covid-infected people develop potentially deadly systemic inflammation, according to a study.

Researchers at the University of Sao Paulo (USP) in Brazil have found that severe COVID-19 disease is associated with an imbalance in a key immune system signaling pathway.

The researchers discovered a “dysregulation”, i.e. a disturbed regulation of the immune system, mediated by adenosine triphosphate (ATP), one of the main energy sources for cellular processes.
