Antigen uptake in the gut
Antigen uptake in the gut
Antigens may be taken up from the gut lumen by 3 different cell types. (A) Soluble antigen can cross the epithelium via transcellular (endocytosis) or paracellular routes. (B) Dendritic cells can extend dendrites into the lumen and sample antigen. (C) M cells in Peyer's patches take up particulate antigens.
