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...

This study aimed to determine the levels of milk cell total protein (TP), reduced nicotinamide adenine dinucleotide phosphate (NADPH), total glutathione (tGSH), activities of glucose-6-phosphate dehydrogenase (G6PD) and glutathione peroxidase (GPx) in subclinical mastitic cows. Milk from each udder was...

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...
