Guardians of the Gut: Mucosal-Associated Lymphoid Tissue (MALT) in Intestinal Health and Disease

Wong li

The mucosal-associated lymphoid tissue (MALT) plays a pivotal role in maintaining intestinal health and safeguarding against a spectrum of diseases. This review delves into the intricate mechanisms by which MALT acts as the guardian of the gut, orchestrating immune responses and contributing to immune tolerance. We explore the structural organization of MALT, emphasizing the gut-associated lymphoid tissue (GALT), and its constituent cells, including lymphocytes, dendritic cells, and specialized follicle-associated epithelium. The communication between MALT and the gut microbiota is a central theme, highlighting the delicate balance that MALT maintains in promoting immune defense while preventing excessive inflammation. We discuss the role of MALT in immunological surveillance against pathogens and the development of immune memory, as well as its involvement in autoimmune disorders, inflammatory bowel diseases, and gastrointestinal cancers. Furthermore, this review underscores the potential therapeutic strategies harnessing MALT for interventions in gastrointestinal health and disease management. Understanding the multifaceted functions of MALT is essential for advancing our knowledge of mucosal immunology and improving clinical approaches to intestinal conditions.
