The purpose of our research group is to identify causes, risk factors (positive and negative), and biomarkers of susceptibility and early diagnosis of multiple sclerosis (MS), Parkinson’s disease (PD), and amyotrophic lateral sclerosis (ALS). Because of their progressive and disabling nature, these diseases have major adverse personal, social, and economic consequences. Prevention and early detection are critical, because there are no cures and the clinical diagnosis typically occurs after substantial and often irreversible neuronal loss, and at a time when neuroprotective interventions are probably too late to be fully effective.
At the core of our work is a series of prospective investigations that integrate genetic, biochemical, and traditional epidemiological approaches, and an interdisciplinary team including basic scientists, epidemiologists, and clinical investigators. Current projects include, among others:
- The investigation of the environmental determinants of MS, with focus on the possible etiological role of the Epstein-Barr virus and other infections and the protective effect of vitamin D and its variations be age, gender and race/ethnicity. This is a collaborative effort with contributions from leading virologists, immunologists and geneticists in the U.S. and Europe.
- An investigation of the role of drugs, diet, and lifestyle in determining PD risk. This project includes collaborations with neurobiologists and clinical investigators and use of biological samples for the discovery of biomarkers for PD. Products of this project include the design of experimental studies to find the mechanisms underlying selected epidemiological findings, most notably the possible protective effects of caffeine, anti-inflammatory drugs, and high plasma levels of urate, and of clinical studies to assess translational implications, including a randomized trial of urate elevation in individuals with early PD.
- Investigation on metabolomic and lipidomic markers for ALS, PD and MS. These studies are based on multiple populations, including large cohorts in the U.S. and participants in a multicenter randomized trials of MS in Europe.
- Investigations on the role of the gut microbiome in the etiology of ALS and PD.
- A large longitudinal study for the early identification of prodromal PD
