Distribution of NgR in the Brain of Rhinolophus affinis

YAO Jing,LU Ya-ping(College of Life Sciences,Anhui Normal University,Wuhu 241000,China)  
An interaction of Nogo with NgR has been suggested to play an important role in limiting axonal growth.By means of immunocytochemistry,the present study investigated the distribution of NgR in the brain of Rhinolophus affinis. The results showed that the NgR protein appeared to be present in all layers of the brain neocortex.In the hippocampus,NgR immunoreactivity was widely located in neurons,mainly concentrated in CA1,CA3 of the stratum pyramidale and dentate gyrus.Neurons in the amygdala,thalamus,paraventricular nucle,supraopticus and suprachiasmaticus also expressed NgR protein.The labeled neuronal cells exhibited immunoreactivity mainly in cytoplasmic membranes,cell bodies and/or neuropil.In white matter,axonal staining for NgR is prominent.In the cerebellum,immunoreactivity was detected in the molecular layer,Purkinje cell layer and granule cell layer.There were numerous granule cells and a few of Purkinje cells stained for NgR.These indicated that the NgR may mediate effects of its ligands on the neuronal cells in various brain regions of Rhinolophus affinis.
