mucosal tolerance

Mucosal tolerance is the immune system’s way of preventing overreaction to harmless substances like food and germs in the nose or gut. When exposed repeatedly to these non-threatening stimuli, the immune response becomes less aggressive, helping to avoid unnecessary inflammation or allergies. This process helps the body distinguish between dangerous pathogens and harmless substances, maintaining immune balance and preventing issues like food allergies or autoimmune reactions. Essentially, mucosal tolerance teaches the immune system to ignore certain everyday exposures to keep the body functioning smoothly without overreacting.
