英文摘要
PROJECT SUMMARY
Alcoholism, also known as alcohol use disorder, is a chronic debilitating disorder characterized by excessive
ingestion of alcohol and impairment in social and occupational functioning. While most investigations of brain
mechanisms mediating this disorder have studied the hypothalamus or mesolimbic regions, recent evidence
focuses attention on a relatively understudied area, the paraventricular nucleus of the thalamus (PVT), which
provides an important relay point between the homeostasisregulating hypothalamus and emotionregulating
limbic nuclei. Utilizing the intermittent access model that leads to voluntary consumption of ethanol at
pharmacologicallyrelevant levels, I plan to test the overall hypothesis that ethanol drinking stimulates the
hypothalamic neuropeptide orexin (OX) to act in the PVT, primarily at the orexin 2 rather than orexin 1 receptor
(and rather than melaninconcentrating hormone at its receptor) and specifically in the anterior rather than posterior
subregion, and that this action, in turn, increases local levels of the opioid enkephalin (ENK) to promote further
ethanol intake. With this sequence of events possibly being critically important in promoting disordered alcohol use,
I propose, in Aim 1, to investigate the neurochemical events that occur following ethanol drinking, from OX
transcription in the hypothalamus to ENK release in the anterior PVT. In Aim 2, I will examine the behavioral results
of these neurochemical changes, testing the effects of OX and ENK injection in the PVT on ethanol drinking and
emotional behaviors and the possibility that these behaviors are naturally increased by elevated endogenous
peptide levels. In Aim 3, I will then look at molecular mechanisms of this OXtoENK connection and examine the
possibility that this is necessary for promoting ethanol drinking. Collectively, by using techniques as varied as
primary neuronal culture, in situ hybridization, and behavioral assessment tests, these studies should provide
significant new information on a relatively understudied nucleus, the PVT, and its potentially major involvement
in ethanol intake. In addition to the publications that should come out of this work, which will allow me to
integrate molecular, cellular, and behavioral findings, the funding of this grant proposal will give me the
necessary training in both research and career development to attain independence as a scientist. I will
additionally take part in advanced coursework and attend seminars and workshops at The Rockefeller
University and through the TriInstitutional Collaboration Network, while participating in national society
meetings. I will receive expert mentorship from my sponsor, Dr. Sarah Leibowitz, as well as my advisory
committee which, together with the abundant resources at The Rockefeller University, will allow me to learn
new experimental methods and gain new perspectives on my research questions. Thus, in the process of
conducting innovative new research, I will gain the skills necessary to successfully transition into a position as
an independent research scientist and to make a significant contribution to the field of alcohol research.
