Mucosal-associated lymphoid tissue (MALT)

Mucosal-associated lymphoid tissue (MALT) is a part of the immune system found in mucosal areas such as the gut, respiratory system, and other surfaces that connect to the external environment. It consists of clusters of immune cells that help protect these areas from infections by recognizing and responding to pathogens. MALT includes structures like the tonsils, Peyer's patches in the intestines, and other lymphoid tissues. It plays a crucial role in maintaining our body's defenses while also managing the balance between responding to harmful invaders and tolerating harmless substances, like food or friendly bacteria.
