Parkinson's Disease (PD)
The treatment of Parkinson's disease (PD) still faces major challenges, including limited blood-brain barrier penetration and disease heterogeneity. Leveraging our pioneering efforts in PD research, Protheragen is at the forefront of developing cutting-edge therapies to enhance the effective management of PD. As your trusted partner in PD drug development research, we provide unparalleled support to meet your research needs.
Overview of Parkinson's Disease (PD)
Parkinson's disease (PD) is the second most common neurodegenerative disorder after Alzheimer's disease, affecting 1% of the population over 60 years old. Clinically, PD is characterized by motor symptoms (bradykinesia, resting tremor, rigidity, postural instability) and non-motor symptoms (cognitive impairment, autonomic dysfunction, sleep disorders, depression). The disease follows a progressive course, with worsening disability over 5-20 years due to relentless neurodegeneration.

Pathogenesis of Parkinson's Disease (PD)
The pathogenesis of Parkinson's disease (PD) primarily involves the progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta, driven by three interconnected mechanisms: (1) abnormal accumulation and prion-like spread of misfolded α-synuclein forming Lewy bodies, (2) mitochondrial dysfunction and oxidative stress due to impaired complex I activity and defective mitophagy (PINK1/PARKIN pathway), and (3) neuroinflammation mediated by chronically activated microglia releasing pro-inflammatory cytokines.

Our Services
As a leader in rare neurodegenerative disease research, Protheragen offers comprehensive preclinical services to advance Parkinson's disease (PD) therapeutics from discovery to validation. Our specialized platforms integrate genetic analysis and disease-specific modeling to replicate disease pathology with high fidelity. Using advanced blood-brain barrier (BBB) models, we optimize central nervous system (CNS) drug delivery while evaluating neuroprotection and off-target effects.
