We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Identifying Excitotoxic Mechanisms in a C. Elegans Model of Axon Destabilization @ Univ of Massachusetts Med Sch Worcester
DESCRIPTION (provided by applicant): Excess ion channel activation can have devastating consequences for the nervous system, often resulting in cell death. Excitotoxic or ion-channel mediated cell death is a major cause of the debilitating loss of neurons that occurs during pathological conditions such as ischemic stroke1, and is also a contributing factor in a variety of human neurodegenerative diseases including amyotrophic lateral sclerosis (ALS)2. Preliminary work on a Caenorhabditis elegans model of excitotoxicity shows that in cases where cell body death is prevented, axonal destabilization still occurs3. The goal of this proposal is to identify the mechanisms underlying synaptic decoupling and altered calcium homeostasis in axons, which occur during excitotoxic cell damage. In Aim 1, I will test the hypothesis that axonal destabilization is mediated through increased calcium stores and requires both voltage gated and ER localized channel receptors. In Aim 2, I will identify the role of calcium in axon destabilization and implicate specific classes of calcium channels in mediating the accumulation of toxic levels of calcium in axons. PUBLIC HEALTH RELEVANCE: Excitotoxicity occurs as a result of many prevalent human pathologies, such as stroke and amyotrophic later sclerosis (ALS). The work proposed will identify the mechanisms that are responsible for mediating excitotoxic cell death. The mechanisms of cell death in axons can be used as targets for the treatment and prevention of axon loss in neurodegenerative diseases.
