Altered expression of SHANK3 proteins has been implicated in multiple neurodevelopmental disorders, including Phelan-McDermid syndrome (PMS), schizophrenia (SZ), and autism spectrum disorders (ASDs). SHANK3B is a postsynaptic density protein that physically links ionotropic NMDA receptors to metabotropic mGlu5 receptors through interactions with scaffolding proteins, a connection essential for long-term potentiation. Previous studies have demonstrated that endosomal trafficking within dendritic spines regulates receptor insertion and recycling, processes fundamental to maintaining excitatory/inhibitory (E/I) balance. Here, we investigated endosomal protein expression and E/I regulatory proteins in a SHANK3B mouse model to better understand sex-dependent contributions to neurodevelopment. Using immunoblotting and immunohistochemistry, we identified sex-specific alterations in hippocamp.. Read More»
