Article Title: Oxytocin Protects Against Corticosterone-Induced DA Dysfunction: An Involvement of the PKA/CREB Pathway
doi: 10.1007/s11064-024-04294-7
Figure Lengend Snippet: Proposed mechanism underlying the neuroprotective effects of OXT against CORT-induced dopamine dysfunction in SH-SY5Y cells. OXT binds to its receptor, resulting in augmented stimulation of cAMP, which serves as an activator of PKA. Subsequently, PKA phosphorylates TH at Ser40 and CREB at Ser133. Phosphorylated CREB can bind to downstream coactivators to orchestrate the transcriptional activity of its target, including the TH gene. This regulatory process contributes to the protective effects of OXT against CORT-induced toxicity, thereby conferring neuroprotection. (Created with BioRender.com/Mahidol University)
