title: Carbonic anhydrase--a marker for particles shed from the epithelium to the lymphoid follicles of the ileal Peyer's patch in goat kids and lambs.
abstract: Carbonic anhydrase (CA) was found to be a marker for 50 nanometer membrane-bounded particles shed from the lateral cell border of follicle-associated epithelial cells (FAE) in the ileal Peyer's patch (PP) of pre- and post-natal lambs and goat kids. The CA-positive particles seemed to filter into the underlying lymphoid tissue where they formed part of the matrix embedding the cells of the follicle centre.
