Intestine Mucosa - an overview | ScienceDirect Topics
The intestinal mucosa represents a location where the immune system is in constant contact with foreign antigens and pathogens, and where immune responses must be tightly regulated to prevent overactivation, inflammation and disease. One key pair of interacting molecules involved in controlling the immune response in the intestine is TL and CD8αα.
