Figure 1. The intestinal immune system.

Figure 1

Pathogens or bacterial gene products can be captured by DC subsets situated within the epithelial layer or residing beneath the epithelial dome. These cells can either activate T and B cells directly or migrate into the mesenteric lymph nodes to present processed immunogens to T and B cells. Activated T and B cells can migrate into the periphery, poised to induce specific immunity against pathogen challenge.
