Nanoparticle with mRNA appears to prevent, treat peanut allergies in mice
Peanut allergies affect 1 in 50 children, and the most severe cases lead to a potentially deadly immune reaction called anaphylactic shock.
Currently, there is only one approved treatment that reduces the severity of the allergic reaction, and it takes months to kick in. A group of UCLA immunologists is aiming to change that.
Taking inspiration from COVID-19 vaccines as well as their own research on the disease, they created a first-of-its-kind nanoparticle — so small it’s measured in billionths of a meter — that delivers mRNA to specific cells in the liver. Those cells, in turn, teach the body’s natural defenses to tolerate ...
