1.   The lateral membrane takes up the entire length of one side of the chamber, pushing the grapes against the other side.

2.   In areas of intestinal metaplasia, gap junctions were occasionally seen between absorptive cells of the villi, but not in the lateral membranes of goblet cells.

3.   A marked staining at the lateral membranes could no longer be observed.

4.   The increased cellular uptake of PT-gliadin in coeliac patients could therefore occur indirectly through endocytosis at the lateral membrane.
