Abstract
The aim of this work was an immunohistochemical
study of the expression of neuronal and glial
proteins, and of gap junctions proteins (connexin
36, connexin 43) in ventral posteromedial (VPMN),
ventral posterolateral (VPLN) and reticular (RТN)
nuclei of the thalamus in rats. It was found that
VPMN and VPLN of the thalamus were
characterized by a homogeneous distribution of
synaptophysin, grouped arrangement of
astrocytes, horizontal orientation of somatostatincontaining
myelinated and unmyelinated nerve
fibers, forming the bundles, and running through
the barreloid septum, expression of connexin 36
and 43 as well as of parvalbumin revealing
barreloids in 4 μm-thick sections. In RTN the
content of myelin basic protein, neurofilaments,
parvalbumin, and somatostatin was increased,
while the amount of glial fibrillary acidic protein and
connexin 43 was moderate, and synaptophysin
and connexin 36 were absent.
