Wnt/β-catenin and D2 receptor signaling crosstalk in disease mechanisms

Wnt/β-catenin signaling is a fundamental regulator of development, tissue homeostasis, and disease progression. Recent studies have suggested functional interactions between Wnt signaling and dopamine D2 receptor (D2DR) pathways, with the AKT-GSK3β axis emerging as a key point of convergence that influences β-catenin stability and transcriptional activity. Through this signaling interface, D2DR may shape diverse biological processes, including neuronal survival, synaptic remodeling, and tumor progression. Importantly, the functional consequences of Wnt-D2DR crosstalk appear to be highly context-dependent, differing substantially between neurological disorders and colorectal cancer. In parallel, advances in organoid systems, single-cell technologies, and real-time biosensing approaches are beginning to provide mechanistic insights into the dynamic regulation of these pathways. Although therapeutic strategies directly targeting Wnt-D2DR interactions remain unavailable, growing evidence supports their potential relevance to disease-specific therapeutic interventions. Therefore, a more comprehensive understanding of this signaling network may provide new opportunities for both mechanistic investigation and translational development.
