What's interesting to me is that one of the biggest booms in pharma over the last ~10 years has been biologics / monoclonal antibodies that treat auto-immune diseases by SUPRESSING cytokines. Examples include TNF inhibitors like Remicade/Humira/Enbrel; or specific IL-XX inhibitors like Dupixent/Cosentyx/Skyrizi/Tremfya/etc; or interferon therapies for MS. These are increasingly used for a broad (unlimited?) set of autoimmune or inflammatory diseases and work by blocking specific cytokines to reduce immune overactivity.
What this treatment does is the opposite side of that coin, it mimics cytokines in order to PROMOTE an immune response.
Immune regulation is an area that deserves a lot more research, and there is going to be learning (harm) along the way. An increasing body of science is pointing to autoimmune diseases being triggered by traditional vaccines, which are then treated by the biologics above that increase the likelihood of other disease due to immunosuppression, which can now be treated(?) by a new immunobooster AKA universal vaccine?
