The GALT and Immunity

The Gut-Associated Lymphoid Tissue (GALT) is a crucial component of the body's immune system, representing approximately 70% of the entire immune system. This highlights the critical importance of gut health for overall immunity.

Functions of GALT

  • Differentiation between harmless antigens (food, commensal bacteria) and pathogens.
  • Production of IgA antibodies to neutralize threats.
  • Maintenance of immune tolerance.
