Most of our work focuses on the human disease multiple sclerosis (MS, the second most common cause of neurological disability in young adults) and its animal model, experimental autoimmune encephalomyelitis (EAE). Our laboratory studies interactions between the immune and nervous systems in the context of autoimmune demyelinating disease. We pose questions about the influence of the CNS microenvironment on the development of local inflammatory responses and, conversely, about the influence of immune mediators on neural stem/progenitor cell (NPC) survival and regeneration/ repair.
One part of our laboratory is devoted to human immunological studies, involving the analysis of peripheral blood mononuclear cell, T and B cells that are collected from patients with MS or other neurological diseases and healthy controls. Currently we are investigating the relationship between the expression of neurotrophins, MS disease activity and various disease modifying treatment effects.
We are investigating the mechanisms by which leukocyte subsets and cytokines interact with NPCs in the repair process; specifically, we are studying the effects of various T cells (Th1, Th17, Th2, Treg) on CNS progenitor cells and axonal regrowth pathways that could affect attempts to repair damaged CNS tissues.
We are also investigating the culture conditions that promote optimal survival and differentiation of the oligodendrocyte lineage from human and mouse NPCs. We will also be testing potential therapeutic agents in NPC system and subsequently in EAE. Our long-term goal is to apply novel neuroprotective therapeutic agents in human clinical trials for MS patients.
