The nature of T cells in the human brain has been deciphered
How T cells protect the brain - health short science news

Using brain tissue from human donors, researchers have identified many characteristics of T cells, which protect the brain against viral infections. It has become of where they reside in the brain precisely, what sort of pro-inflammatory substances they produce and secrete (the cytokines), and how their activity is controlled. Considering the latter, T cells appear to express CTLA-4 and PD-1 in huge amounts, which are known as inhibition points of their activity. This is important information for further study and treatment of neurological autoimmune diseases such as multiple sclerosis.
