Ancient Part of Immune System May Underpin Severe COVID
One of the immune system’s oldest branches, called complement, may be influencing the severity of COVID disease, according to a new study from Drs. Sagi Shapira and Nicholas Tatonetti at the Department of Systems Biology.

Among other findings linking complement to COVID, the researchers found that people with age-related macular degeneration—a disorder caused by overactive complement—are at greater risk of developing severe complications and dying from COVID.
The connection with complement suggests that existing drugs that inhibit the complement system could help treat patients with severe COVID-19.
