NMDA(N-methyl-D-aspartate) receptors are a subtype of excitatory transmitters-glutamate receptor which belong to a heteromeric ligand-gated ionotropic receptors and play an important role in many complex physiological and pathological processes, such as nerve development, neuronal excitatory synaptic transmission, synaptic plasticity, central sensitization and neuronal death.
NMDA(N-methyl-D-aspartate)受体是兴奋性神经递质谷氨酸受体的一种亚型,是一种异聚体配体门控型离子通道,参与体内神经发育、神经元的兴奋性突触传递、突触可塑性、中枢敏化、神经元死亡等多种不同的生理和病理过程。

We introduced improved primary mixed glial culture and different-attachment method to isolate and purify the OPCs, the cells were proliferated in serum-free medium, flow cytometry and immunohischemistry methods were employed to estimate the purity of cultured OPCs. Their abilities of differentiation and expression of trophic factors were identified by RT-PCR and immunostaining. Several methods including TUNEL and MTT were adopted to estimate the protective effects of conditioned culture medium from oligodendrocyte lineage cells on the primary cultured cerebellar granule neurons. Intravitreal transplant of OPCs, combined with retrograde fluorescent labeling the superior colliculus and intraorbital optic nerve transection, were used to investigate the protective effects of OPCs on the axotomized RGCs in vivo. Intravitreal transplantof OPCs or NSCs on the newborn rats, and retinal transplant of OPCs on the young rats were performed, to observe the myelin formation in the retina at different stages after cellular transplantation. Optic nerve transection was carried out on some rats with myelinated retinae, to study the influence of myelination on the injuried RGCs.

To understand the basic properties, underlying mechanisms and functions of the short-term synaptic plasticity of thalamocortical visual pathway, we combined in vivo field potential recording, focal drug application technique and neuron models, to explore the short-tem synaptic plasticity of rat major thalamocortical visual pathway (from lateral geniculate nucleus to primary visual cortex) and extrageniculate pathway (from lateral posterior nucleus to primary visual cortex), as well as the role of short-term depression in the neuronal correlated firing detection.
