of Ph.D. thesis Molecular mechanisms of regulation of trafficking and function of different subtypes of NMDA receptors in hippocampal neurons Mgr. Kristýna Skřenková N-methyl-D-aspartate (NMDA) receptors are ionotropic glutamate receptors that play a key role in the mammalian central nervous system. Under physiological conditions, these receptors are important for excitatory synaptic transmission and memory formation. However, under pathological conditions, their abnormal regulation or activation may lead to many neurological and psychiatric disorders, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, epilepsy or schizophrenia. Previous studies have shown that the number and type of NMDA receptors on the cell surface are regulated at multiple levels, including their synthesis, folding, internalization or degradation. During the trafficking of NMDA receptors to the cell surface membrane, both the agonist binding and receptor activation are examined. Moreover, NMDA receptors undergo many posttranslational modifications such as palmitoylation, phosphorylation or N-glycosylation. In this thesis, we studied the molecular mechanisms that may affect the trafficking and functional properties of NMDA receptors in mammalian cells and rat hippocampal neurons. Specifically, we studied i)...
