Mast cells, brain: rats & humans

Medline searches (including abstracts) and perusal of several recent 
articles indicates the need for additional research regarding mast cells 
would be helpful regarding mast cell locations, contents, and migrations. 

Most recent articles seem to generalize about human-brain mast cells 
primarily from human phenomena such as Alzheimer's (etc) and from 
increasing data derived from the study of rats, wherein findings suggest 
quite nifty nuances such as developmental versus adult patterns (1), 
mast cell differences in specific tissues (2), and an increasingly wide 
number of brain tissues having mast cells in non-disease states (3-4).

So far as I can tell (and would hope to be informed otherwise if such 
studies exist), whether or not mast cells in any given brain region 
transcribe the GnRH gene and produce GnRH remains to be determined. 
Also, whether mast-cell GnRH (be it collected or produced) exists in 
primates remains to be determined for any of the neural tissues involved in 
olfactory/vno/respiratory-epithelial processing and in reproduction, 
including the habenula. 
   But aside from the Silver R et al findings regarding GnRH, mast cells, 
and the avian habenula, a general theme that seems to be emerging is that 
mast cells in the brain (in non-diseased states) contribute in various 
ways to neuronal function (1-4).
