Focus

Cellular and molecular mechanisms of neurodegeneration and neuroprotection.

Research Summary

Acute and chronic injurious processes in the brain lead to the activation of signaling cascades that eventually result in the demise of neurons. In Dr. Aizenman's laboratory, molecular pathways leading to cell death are being carefully dissected in order to provide novel therapeutic targets to treat neurodegenerative disorders. This laboratory works on potential common final mediators of cell death signaling events that can be effectively targeted to treat neural disorders. This work is primarily focused on acute neuronal injury, such as stroke, although the results obtained from these studies could have broader applications to more chronic neurodegenerative conditions. Over the last 22 years, the laboratory has investigated redox and photic regulation of NMDA receptors, excitotoxicity, dopamine oxidation pathways, zinc-mediated neurotoxicity, and Kv2.1 potassium channel facilitated forms of neuronal apoptosis, among other topics.
