Oxidative stress and dysregulated long noncoding RNAs in the pathogenesis of Parkinson's disease.

Parkinson's disease (PD) is a progressive age-related neurodegenerative disease whose annual incidence is increasing as populations continue to age. Although its pathogenesis has not been fully elucidated, oxidative stress has been shown to play an important role in promoting the occurrence and development of the disease. Long noncoding RNAs (lncRNAs), which are more than 200 nucleotides in length, are also involved in the pathogenesis of PD at the transcriptional level via epigenetic regulation, or at the post-transcriptional level by participating in physiological processes, including aggregation of the α-synuclein, mitochondrial dysfunction, oxidative stress, calcium stabilization, and neuroinflammation.

Positive feedback loop involving AMPK and CLYBL acetylation links metabolic rewiring and inflammatory responses.

Metabolic rewiring underlies effective macrophages defense to respond disease microenvironment.
