| Research Abstract |
To study the pathogenesis of autism, we analyzed the synaptic function in mouse models harboring Neuroligin-3 R451C mutation. We found that the synaptic transmission mediated by NMDA glutamate receptors was enhanced in the hippocampus of these mice and this was due to the increased number of the receptor on the synaptic membrane. In addition, we found morphological abnormalities in the mutant synapses. These findings may provide insight into understanding the pathopysiology and developing treatments of autism.
