Mucosa-associated lymphoid tissue

(MALT); lymphoid tissue associated with human mucosa, such as the tonsils, the vermiform appendix and Peyer patches of the small intestine

Description
Mucosa-associated lymphoid tissue is distributed over mucosal linings and in human measures a total of approximately 400 m2, making it the largest part of the lymphoid tissue. The large surface area contributes to MALT-mediated protection from different and numerous foreign antigens.
