A study used surveys and blood tests from adults aged 50 and older who take part in the Health and Retirement Study. People reported routine unfair treatment, like less respect or worse service because of who they are.
Researchers measured markers of adaptive immunity, looking at types and stages of T and B cells. They found that people who reported more everyday discrimination had higher counts of terminally differentiated, or exhausted, immune cells. The study did not find more young “naïve” immune cells.
The study was led by Emiko Kranz at NYU. The authors say the work is an early step and more research is needed.
