Detailed research
description:
Our lab focuses on brain inflammation - the activation of glial cells - a
critical and detrimental feature of several neurodegenerative disorders,
including Alzheimer's disease, AIDS-related dementia, multiple sclerosis, and
stroke-induced ischemia. Our overall aim is to identify and characterize
logical drug discovery targets for the development of therapeutics to rectify
this inflammatory process. We employ multidisciplinary approaches rooted in
molecular and cellular biology, as well as in protein-based chemistry,
including: molecular manipulation of intracellular signal transduction
pathways, promoter and gene expression analyses, high throughput screening
methods for enzymes and inhibitors, protein structure-function analyses, and
computerized structure-based inhibitor design. By using these approaches, our
lab has shown that glial activation is a robust, neuroinflammatory process
that involves the complex coordination of signal transduction pathways, gene
expression, and protein modulation. Moreover, a significant consequence of
this glial activation is the generation of pro-inflammatory and oxidative
stress responses. Inflammation and oxidative stress in the brain can be
neurotoxic, and are suggested to be an important component in
neuropathogenesis. Current studies include investigation of how activated
glia participate in transgenic models of disease and human pathology, the
interactions of neurons and activated glia during inflammation, and discovery
of ligand modulators of glial activation pathways.
