Mucosal-associated lymphoid tissue (MALT) is a component of the immune system found in mucosal surfaces, such as the gut, respiratory tract, and other areas. It plays a crucial role in protecting the body from pathogens that enter through these surfaces. MALT includes structures like Peyer’s patches in the intestines and tonsils in the throat. MALT contains various immune cells, including B cells and T cells, which help identify and respond to foreign invaders. By producing antibodies and coordinating immune responses, MALT helps maintain the body’s defense against infections while also tolerating harmless substances, such as food and beneficial bacteria.
