Sex-dependent dysregulation of the gut-brain NPYergic system in a mouse model of autism spectrum disorder - Scientific Reports

|
By Beatriz Malcata Martins, Joao Martins, Miguel Castelo-Branco, Joana Gonçalves
| Nature Verified
Abstract The microbiome-gut-brain axis has been increasingly recognized for its role in the pathophysiology of autism spectrum disorder (ASD), yet the underlying molecular mechanisms remain poorly understood. Neuropeptide Y (NPY), a key modulator of gut-brain communication, may play a pivotal role in this axis. This study investigated the sex-specific molecular profile of the NPY system in gut-brain communication via a genetic mouse model of ASD, the Nf1+/- mice.
