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.

Pka and Npy Signaling in Ethanol-Induced Sensitization @ University of North Carolina Chapel Hill
[unreadable] DESCRIPTION (provided by applicant): Low neuropeptide Y (NPY) and cAMP-dependent protein kinase A (PKA) signaling are both associated with increased ethanol consumption and enhanced sensitivity to ethanol-induced locomotor stimulation. Recent evidence shows that PKA signaling drives NPY synthesis. Therefore, the guiding hypothesis of the present proposal is that the increased ethanol intake and sensitivity to ethanol-induced locomotor sensitization that are characteristic of mutant mice with low central PKA activity (i.e., Rll-beta deficient mice) are consequences of blunted NPY signaling. Specific Aim 1 will utilize immunohistochemistry and real-time PCR to determine if PKA mutant mice have low NPY signaling at baseline and in response to ethanol administration in candidate brain regions. Specific Aim 2 will utilize a recombinant adeno-associated viral vector (rAAV) to determine if site-directed overexpressioh of NPY in the striatum, nucleus accumbens, and/or amygdala will protect against increased sensitivity to ethanol-induced locomotor sensitization and elevated ethanol drinking in PKA mutant mice. These studies will provide important insight into the interactions between PKA and NPY signaling in modulating neurobiological responses to ethanol. [unreadable] [unreadable] [unreadable]
