Answer:
express the cytokine, TGF-beta
Step-by-step explanation:
An autoimmune disease is a condition in which your immune system attacks your body mistakenly. The immune system protects our body against germs including bacteria and viruses. It sends out an army of fighter cells to attack them.
Immune privileged sites, such as the brain, the eye, and the testis, are often the targets of autoimmune attack but the priming and differentiation of effector cells specific for antigens found in the brain, for example, is generally prevented as immune-privileged sites express the cytokine, TGF-beta.
