LRRK2

The root of Parkinson’s disease (PD) points to a poorly regulated electron transport chain leading to mitochondrial damage, where many proteins need to work cohesively to ensure proper function.  The two key players of this pathway are PINK1, also known as PTEN or PARK6, and Parkin, also known as PARK2 - where PINK1 acts as an upstream effector of Parkin to regulate mitochondrial dynamics.  Mitochondria must maintain a healthy equilibrium and do so by undergoing a series of fission and fusion event

Tyrosine hydroxylase (TH) is a crucial enzyme involved in the biosynthesis of dopamine, norepinephrine and epinephrine in the brain.

Parkinson's disease affects the nervous system which controls movement. Damage to the levels of dopamine in the brain impairs the ability to relay messages to parts of the body which control movement. While the exact cause of the disease is unknown, researchers are examining genetic causes linked to the LRRK2 gene and environmental factors.

Identified almost two centuries ago, Parkinson's disease is a neurodegenerative disorder that afflicts an estimated 4-6 million worldwide (www.parkinsons.org). The prevalence of Parkinson's disease is expected to grow considerably as the average age of the population in developed countries increases.  Despite the hundreds of millions of dollars devoted annually to Parkinson's research, there is relatively little known about the disease and its treatment.
