One
of the major types of diabetes (type 1 or insulin-dependent diabetes
mellitus) is an autoimmune disorder in which antibodies against B
cells depress their activity and eventually kill the cells, leading
to the need for insulin injections. The image to the right shows
early stages of lymphocytic destruction of an islet.
Gastrointestinal endocrine system --
Review the material on Junqueira page 360 and Table 15-1 about the diffusely-located neuroendocrine in the digestive and respiratory mucosa and the kinds
of hormones secreted by these cells. These cells are difficult to
demonstrate in
routinely-prepared slides, but they are very important
physiologically and you should know their anatomical locations and
functions.
Why are these cells sometimes
called “argentaffin cells” or “enterochromaffin cells”?
