| Research Abstract |
Glutamate is the major excitatory neurotransmitter in the central nervous system. Through this program, we focused on the formation and the regulation of glutamatergic excitatory synapses. Our findings revealed that the localization and trafficking of ionotropic glutamate receptors are regulated by tyrosine phosphorylation and palmitoylation in excitatory synapses. In addition, we showed that RhoA-mediated signaling pathway regulates IL1RAPL1-dependent formation and stabilization of glutamatergic synapses. Mutations of IL1RAPL1 and some palmitoyl acyl transferases are associated with mental disorders, indicating the crucial role of these molecules in the proper formation and regulation of glutamatergic synapses.
