Hear me out, measles can cause immune system amnesia. People with autoimmune disorders have immune systems that want to kill them. What if we use the immune system amnesia property of measles to reset the immune system of people suffering with autoimmune disorders? Maybe we could do some crispr on the measles virus to make it not as dangerous or something like that first though.
This is actually being done with immune reset gene therapy though I’m not sure if it’s at all based on how the measles virus works. It’s also a potential cure for Crohn’s, Type 1 Diabetes, and many other ailments. A similar technique could also allow organ transplants without immunosuppressants through teaching the immune system to recognize the organ as part of the body.
