Research Interests: The molecular basis for the responses of neural stem cells (NSCs) to injury and chronic neuroinflammation is unknown. In mouse models of multiple sclerosis, chronic neuroinflammation has deleterious effects in NSCs (Imitola et. al., 2011) by decreasing their self-renewal capacity.

The goal of the Imitola laboratory is to identify and validate genes that mediate the responses of neural stem cells (NSCs) to central nervous system (CNS) injury in multiple sclerosis and brain cancer in the so-called injury-induced stem cell niches.

Few candidate genes have been validated for NSCs function in CNS pathology such as the chemokine receptor CXCR4 that mediates the migration of human NSCs to sites of injury and brain tumors. (Imitola et al, 2004) Imitola's team hopes to translate novel molecular targets on NSCs to enhance human central nervous system repair and regeneration.

Current Research:

  1. Inflammation transcriptional control of NSCs and brain cancer stem cell intrinsic properties
  2. Modeling inflammation-induced neurodegeneration and repair with iPSCs

iPS Cells Phenogenetic Map Project - The iPS cell phenogenetic map project “iPhemap” is a comprehensive, continuously updated database that aims to provide a field synopsis and catalog all of the in vitro CNS cell-derived disease phenotypes from induced pluripotent stem cells (iPSCs) derived from patients with neurological diseases.

Research Techniques: iPSCs, cell culture, isolation of neural stem cells from multiple sclerosis models, confocal microscopy, organotypical slices, RNA isolation and gene expression analysis with computational biology tools
