Core Tip
Core tip: Schizophrenia is a psychiatric disorder affecting approximately 1% of the world population. Current treatments inadequately redress the cognitive impairments associated with the disease. In light of that we discuss the role of the cholinergic system, in particular the muscarinic M1 receptor, in schizophrenia and cognition and how allosteric compounds are being developed to address this undertreated aspect of the disease. We also discuss and compile mutagenesis studies of the muscarinic M1 receptor and how they relate to allosteric binding and function.
