Parkinson’s Disease (PD) is a progressive neurodegenerative disorder characterized by dopaminergic neuron loss in the substantia nigra, resulting in both motor and non-motor symptoms. Genetic predispositions, oxidative stress, and inflammatory responses contribute significantly to disease progression. This study aimed to investigate the expression of the CNTF gene and evaluate its potential neuroprotective role in Parkinson’s Disease models, correlating gene expression with motor symptom severity and disease progression. A total of 80 individuals were enrolled, including 55 clinically diagnosed PD patients and 25 age-matched healthy controls. Blood samples were collected, and ELISA (CLIA, Chemiluminescence Assay) was used to measure CNTF protein levels. The study revealed a significantly reduced expression of CNTF in PD patients compared to controls (p<0.01). Lower CNTF levels were strongly associated with advanced stages of PD. These findings support a potential role of CNTF in mitigating neuronal loss in PD. Decreased CNTF expression may contribute to neuronal vulnerability in Parkinson’s Disease. CNTF could be a potential biomarker and therapeutic target for slowing disease progression and enhancing neuroprotection.
