LRRK2 Targeting Strategies as Potential Treatment of Parkinson's Disease.

ABSTRACT: Parkinson's Disease (PD) affects millions of people worldwide with no cure to halt the progress of the disease. Leucine-rich repeat kinase 2 (LRRK2) is the most common genetic cause of PD and, as such, LRRK2 inhibitors are promising therapeutic agents. In the last decade, great progress in the LRRK2 field has been made. This review provides a comprehensive overview of the current state of the art, presenting recent developments and challenges in developing LRRK2 inhibitors, and discussing extensively the potential targeting strategies from the protein perspective. As currently there are three LRRK2-targeting agents in clinical trials, more developments are predicted in the upcoming years.

Project description:Parkinson's disease (PD) is caused by progressive degeneration of dopamine (DA) neurons in the substantia nigra pars compacta (SNpc), resulting in the deficiency of DA in the striatum. Thus, symptoms are developed, such as akinesia, rigidity and tremor. The aetiology of neuronal death in PD still remains unclear. Several possible mechanisms of the degeneration of dopaminergic neurons are still elusive. Various mechanisms of neuronal degeneration in PD have been proposed, including formation of free radicals, oxidative stress, mitochondrial dysfunction, excitotoxicity, calcium cytotoxicity, trophic factor deficiency, inflammatory processes, genetic factors, environmental factors, toxic action of nitric oxide, and apoptosis. All these factors interact with each other, inducing a vicious cycle of toxicity causing neuronal dysfunction, atrophy and finally cell death. Considerable evidence suggests that free radicals and oxidative stress may play key roles in the pathogenesis of PD. However, currently, drug therapy cannot completely cure the disease. DA replacement therapy with levodopa (L-Dopa), although still being a gold standard for symptomatic treatment of PD, only alleviates the clinical symptoms. Furthermore, patients usually experience severe side effects several years after the L-Dopa treatment. Until now, no therapy is available to stop or at least slow down the neurodegeneration in patients. Therefore, efforts are made not only to improve the effect of L-Dopa treatment for PD, but also to investigate new drugs with both antiparkinsonian and neuroprotective effects. Here, the advantages and limitations of current and future therapies for PD were dicussed. Current therapies include dopaminergic therapy, DA agonists, MAO-B inhibitor, COMT inhibitors, anticholinergic drugs, surgical procedures such as pallidotomy and more specifically deep brain stimulation of the globus pallidus pars interna (GPi) or subthalamic nucleus (STN), and stem cell transplantation.
