- APOPTOTIC INSULTS SUPPRESS MARKERS NEURONAL PLASTICITYCarl Cotman; Fiscal Year: 2004..Together, these experiments may provide support for a mechanism (s) accounting for some of the well-known changes in brain aging and AD, including reduced activity dependent plasticity, synaptic integrity and neuronal survival. ..
- ABeta Immunization in AgingCarl Cotman; Fiscal Year: 2005..Overall, this project should provide unique insight into the efficacy of immunization with fibrillar Abeta and have direct implications for the design of human clinical trials. ..
- MECHANISMS OF PATHOLOGICAL NEURITIC & SOMAL DEGENERATIONCarl Cotman; Fiscal Year: 2002..The studies proposed in this application will provide new and basic biological findings potentially relevant to a wide array of normal and pathological events involving synaptic remodeling and neurite degeneration. ..
