What is MALT and its function?
The mucosa-associated lymphoid tissue (MALT) initiates immune responses to specific antigens encountered along all mucosal surfaces. MALT inductive sites are secondary immune tissues where antigen sampling occurs and immune responses are initiated.
Is MALT found in lymph nodes?
MALT may consist of a collection of lymphoid cells, or it may include small solitary lymph nodes. Lymph nodes contain a light-staining region (germinal center) and a peripheral dark-staining region. The germinal center is key to the generation of a normal immune response. The location of MALT is key to its function.
Is MALT lymphoma curable?
