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.
Probably not a good idea, since measles tends to increase risk of something going wrong in the immune system thus triggering autoimmune diseases.
We have drugs that do similar things to measles in the specific sense of wiping out “immune memory” but often in a more targeted, more controlled, and less “random” manner than measles. Like Rituximab or Daratumab that deplete memory B-cells in different ways. They are effective for some subsets of autimmune diseases.
For example Rituximab is the gold standard treatment for Rhematoid Arthritis (RA).
