Members of the Neuron-Specific Gene family (NSG1-3) play critical roles in excitatory synaptic transmission via regulation of AMPA receptor surface expression within the post-synaptic density (PSD). While NSG1 and NSG3 regulate AMPAR recycling and endocytosis, respectively, the function of NSG2 has remained elusive. Here we undertook a series of studies to assess the role of NSG2 in excitatory synaptic transmission. We found that a portion of NSG2 punctae localized with HOMER1 and surface AMPARs at excitatory synapses and that NSG2 AMPAR subunits in mouse brain. Knockout of NSG2 selectively impaired the frequency of AMPA mEPSCs, while overexpression caused a significant …

Determining The Pathological Effects Of Prenatal Alcohol Exposure On Peripheral Neuropathy Via Spinal And Peripheral Immune Mechanisms, Joshua J. Sanchez

Previous studies have suggested that children with Fetal Alcohol Spectrum Disorder (FASD) display hypersensitivity to light touch. In support of this notion, we have demonstrated that applying a chronic constriction injury (CCI) to the sciatic nerve of rats that have prenatal alcohol exposure (PAE) results in heightened sensitivity to light touch, clinically termed allodynia. These observations coincided with heightened glial activation and enhanced peripheral immune reactivity. Considering allodynia is known to be mediated by both peripheral immune responses and spinal glial activation, it is reasonable to speculate that allodynia following PAE may be mediated through an alteration of immune reactivity. …
