The work summarized in this review indicates that \u03b13\u03b24\u2010containing and \u03b14\u03b22\u2010containing neuronal nAChRs, and possibly other subtypes, are inactivated by elevations in intracellular reactive oxygen species (ROS). This review discusses a model for the molecular mechanisms that underlie this inactivation. In addition, we explore the implications of this mechanism in the context of complications that arise from diabetes. We review the evidence that diabetes elevates cytosolic ROS in sympathetic neurons and inactivates postsynaptic \u03b13\u03b24\u2010containing nAChRs shortly after the onset of diabetes, leading to a depression of synaptic transmission in sympathetic ganglia, an impairment of sympathetic reflexes. These effects of ROS on nAChR function are due to the highly conserved Cys residues in the receptors: replacing the cysteine residues in \u03b13 allow ganglionic transmission and sympathetic reflexes to function normally in diabetes. This example from diabetes suggests that other diseases involving oxidative stress, such as Parkinson's disease, could lead to the inactivation of nAChRs on neurons and disrupt cholinergic nicotinic signalling.<\/jats:p>","DOI":"10.1113\/jphysiol.2011.214007","type":"journal-article","created":{"date-parts":[[2011,10,4]],"date-time":"2011-10-04T03:15:04Z","timestamp":1317698104000},"page":"39-47","source":"Crossref","is-referenced-by-count":36,"title":["Reactive
