Scientists have identified specific proteins in common food sources like corn, soy, and wheat that signal to the immune system that they are safe to eat. Regulatory T cells, also known as Tregs, play a key role in this process, scanning food for these key proteins and calming the immune system when they find them.
Researchers have identified three new proteins, called epitopes, that help the body determine 'safe' foods, aiding in food tolerance and allergy understanding. The epitopes were found in seed proteins from corn, wheat, and soybean, and interact with regulatory T cells to inform tolerance-or-rejection decisions.
