The Martinez laboratory investigates novel targets in attenuating the unwanted side-effect in the treatment of Parkinson’s disease (PD) known as L-DOPA induced dyskinesia (LID). Using a validated rat model of Parkinson’s disease, we are able mimic symptoms similar to LID and test various pharmacological compounds on whether they are able to decrease LID without affecting the therapeutic benefits of L-DOPA. Targets of interest that we investigate in decreasing LID include the endocannabinoid and peroxisome proliferator-activated receptor systems. Using the same validated rat model of PD, we are also investigating the relationship between traumatic brain injury and the development/progression of PD.

Project Title: Validation of PPARgamma Agonists as Anti-Dyskinetic Drugs
Role: PI Description: Despite L-DOPA initial beneficial effects in treating Parkinson’s disease, its prolonged use results in the development of abnormal involuntary movements known as dyskinesia. Recent evidence suggests that activation of the nuclear receptor, PPARgamma, ameliorates these unwanted side effects once they are fully established. This proposal investigated whether co-administration of L-DOPA and a PPARgamma agonist (rosiglitazone) prevents the development of dyskinesias in a rodent model of Parkinson’s disease.
