MALT tissues

MALT (mucosa-associated lymphoid tissue) refers to immune system structures located within the mucous membranes of the body, such as the digestive, respiratory, and urogenital tracts. These tissues act as the first line of defense against pathogens by detecting and responding to harmful microorganisms that enter through these mucous surfaces. MALT includes specialized tissues like the tonsils, Peyer’s patches in the intestines, and other lymphoid areas. They contain immune cells that can identify threats and initiate immune responses locally, helping protect the body without the need for a full systemic immune activation.
