Dysregulated immunity has been implicated in the pathogenesis of neurodevelopmental disorders but its contribution to synaptic and behavioral deficits in Rett syndrome (RTT) remains unknown. P2X7 receptors (P2X7Rs) are unique purinergic receptors with pro-inflammatory functions. Here, we report in a

Primary neuronal cultures underpin diverse neuroscience experiments, including various protein analysis techniques, such as Western blotting, whereby protein extraction from cultured neurons is required. During immunoblotting experiments, we encountered problems due to a highly-abundant protein of 65-70 KDa present in
