Progress in Parkinson's disease animal models of genetic defects: Characteristics and application.

Abstract

Parkinson's disease (PD) is the second major progressive neurodegenerative disease, which critically impacts patients' quality of life. Based on genetics, animal models of genetic defects created by gene editing technology have clear advantages in reflecting PD's pathogenesis and pathological characteristics and exploring potential therapeutic targets for PD. In this review, we summarized animal models of genetic defects in various pathogenesis of PD, including α-synuclein abnormal encoding, autophagy-lysosome system defects, ubiquitin protease system defects, and mitochondria-related dysfunction, and discuss their respective advantages, limitations, and application directions to provide a reference for the application of animal models of PD and research on anti-PD therapy.
