American study: A type of immune cell may combat diseases of aging. The study was conducted on mice.
The cells involved are known as chimeric antigen receptor (CAR) T cells. T cells help coordinate the body's immune response, and they directly kill pathogens. Since 2017, the US Food and Drug Administration has approved 6 immunotherapies belonging to this family that are used to treat various cancers. A number of positive indications have emerged that this live drug could be harnessed to treat other diseases such as autoimmune disorders.
