The patches have B and T dependent regions and germinal centres. A specialised epithelium lies between the patch and the intestine. Involved in gut associated immunity. (18 Nov 1997) |
| agminate glands | Lymphoid organs located in the sub mucosal tissue of the mammalian gut containing very high proportions of IgA secreting precursor cells.
