Modeling the pathological brain-gut axis in Parkinson's disease using human iPSC derived brain-intestinal assembloids

Akihiro Yamagchi, Kei-ichi Ishikawa, Wado Akamatsu

This study uses human iPSC-derived brain-intestinal assembloids to show synuclein propagation from brainstem to enteric neurons and identifies NRXN1-NLGN2 signaling as a key mediator.
