Scientists have linked insulin resistance to an increased risk of developing major depressive disorder. …
Study links severe COVID-19 to increase in autoantibodies
Hospitalized COVID-19 patients are substantially more likely to harbor autoantibodies —antibodies directed at their own tissues or at substances their immune cells secrete into the blood …
Study shows why second dose of COVID-19 vaccine shouldn’t be skipped
The second dose of a COVID-19 vaccine induces a powerful boost to a part of the immune system that provides broad antiviral protection. …
Evidence of brain inflammation in severe COVID-19
Comprehensive molecular study of the brains of people who died of COVID-19 reveals unmistakable signs of inflammation and impaired brain circuits. …
