Taltirelin, TRHR, and TH in Striatal Neurons
2026-08-08
Zhu et al. identify a previously underappreciated TRHR–MAPK–RARα–DRD2 signaling axis through which Taltirelin induces tyrosine hydroxylase expression in striatal medium spiny neurons. The work connects Taltirelin’s behavioral effects in a hemi-Parkinson’s disease model with cellular remodeling in the striatum, while also defining important limits for interpreting TH induction as functional dopamine replacement.
