Therapeutic potential of KATP channels in the attenuation of Parkinson's disease pathogenesis and progression - A review.

Parkinson's disease (PD) is one of the most prevalent progressive neurodegenerative diseases today. However, existing treatments primarily focus on symptom management rather than attenuating disease progression and pathogenesis. ATP-sensitive potassium (KATP) ion channels play a significant role in motor control and coordination within the basal ganglia and have been implicated in the dopaminergic depletion mechanisms underlying PD. Recent studies have explored the potential of KATP channel inhibitors to slow PD pathogenesis and progression. Both pharmacological inhibition and genetic inactivation of these channels have been shown to reduce oxidative stress, dopamine (DA) depletion, and subsequent motor deficits. Contrastingly, alternative evidence suggests that KATP channel openers (KCOs) may elicit similar effects, highlighting the need for further exploration of KATP-mediated DA depletion mechanisms in PD. Future studies expanding our understanding of the mechanistic action of KATP in PD are essential to effectively leverage the channel's potential as a therapeutic target for combating PD pathology.
