Parkinson's disease (PD) is one of the most common neurodegenerative diseases in middle and old age. The symptoms of PD are myotonia, quiescent tremor, bradykinesia, gait difficulty, postural instability, etc. The pathological changes of PD are: selective progressive loss of melanin-containing dopaminergic neurons in the dense part of the substantia nigra, and the resulting decrease in striatal dopamine content, accompanied by protein aggregation and the formation of eosinophilic inclusions - Lewy bodies. The pathogenesis of PD has not been fully clarified, which may be related to environmental factors, genetic factors, mitochondrial dysfunction, oxidative stress, immune abnormalities, apoptosis and many other factors.
The role of genetic factors in the pathogenesis of Parkinson's disease has received increasing attention. At present, it has been found that multiple gene mutations may be involved in the pathogenesis of PD. Mutations in genes cause abnormalities in protein function, which is detrimental to the survival of dopaminergic neurons. The amino acid substitution Thr53Ala in SNCA destroys the α-helix of SNCA and is prone to form a β-sheet structure, resulting in loss of function of normal proteins. The mutated SNCA is involved in the self-aggregation of proteins and forms amyloid structures. UCH-L1 protein can hydrolyze the poly ubiquitin into free ubiquitin, which can be further recycled. When the UCH-L1 gene is mutated, the hydrolase activity is weakened, and the polyubiquitin cannot be decomposed into monomers through the ubiquitin cycle, which makes the target protein degradation barrier, leading to protein aggregation and the formation of Lewy bodies. DJ-1 is a hydroperoxide-reactive protein, which has the function of anti-oxidative damage. Mutations in the PARK7 gene cause dysfunction of the DJ-1 protein, which increases damage to neurons in response to oxidative stress. PINK1 protein is a mitochondria-incorporated serine/threonine kinase located on mitochondria that maintains mitochondrial stability. PINK1 has a neuroprotective effect, which can protect nerve cells from mitochondrial dysfunction and oxidative stress. Mutations in the PINK1 gene result in a decrease in the protective effect on neurons, which causes PD. More genes associated with the disease can be found in the gene list.
