Abstract Overall
The Alcohol Research Center of The Scripps Research Institute (TSRI-ARC) proposes to continue its
interdisciplinary program focused on the theme of the central nervous system effects of alcohol. For this
renewal application, the TSRI-ARC (P60) will consist of 9 components, including 3 Cores (Administrative,
Animal Models and Information Dissemination) and 5 Research Projects (Molecular, Neurophysiology,
Neurocircuitry, Neurochemistry, and Clinical). The overall hypothesis of the TSRI-ARC as an integrated whole
is that the central stress systems become activated during the withdrawal/negative affect stage and persist into
protracted abstinence (in the preoccupation/anticipation stage), and such neuroadaptive changes associated
with chronic drinking also produce an evolving set of neurobehavioral symptoms that include hypohedonia,
anxiety, irritability, negative affect, hyperarousal, and sleep disturbances, all of which contribute to relapse and
impede recovery. The specific subhypotheses are: 1) The transition from acute withdrawal to protracted
abstinence includes compulsive-like responding for ethanol and negative emotional behavior that involves
changes in interconnected brain areas: the extended amygdala, the medial prefrontal cortex, and the anterior
insula. 2) The altered activity in these circuits reflects actions of stress-related system including
glucocorticoids, serotonin, hypocretin, and corticotropin-releasing factor. 3) Cellular neuroadaptations are
associated with altered dynamics of the microtubule cytoskeleton, which may in turn mediate the structural
remodeling of neuronal dendrites. 4) Novel neurobiological targets identified by the TSRI-ARC will significantly
attenuate the reinstatement of compulsive-like alcohol seeking, excessive drinking, and anxiety-like behavior;;
and 5) drug candidates for these targets will be active in a human lab model of protracted abstinence where
they will reduce drinking, craving, negative affect, and executive function deficits. We believe the proposed
innovative approaches for testing these hypotheses will provide valuable insight into novel approaches for
treating alcoholism and relapse in the humans.
The TSRI-ARC also supports the Center at Large, which includes: 31 R01s, 10 R21s, 3 U01s, 1 U24, 2 R37s,
2 R13s, and one T32 NIAAA training grant associated with this grant. Members of the Center at Large have
access to the Cores of the TSRI-ARC, the NIAAA Integrative Neuroscience Initiative on Alcoholism (INIA)
Consortia. Training and information dissemination to the San Diego community will be effected by the training
opportunities of the Center including a T32 NIAAA training grant and the Information Dissemination Core.
Public Health Relevance Statement
Narrative
This Center proposes to continue its interdisciplinary program focused on the theme of the central nervous
system’s effects of alcohol. Dysregulation in the brain stress system mediates the transition from acute
withdrawal to protracted abstinence to promote vulnerability to relapse, and our ARC is designed to translate
our discoveries of preclinical TSRI-ARC studies for potential therapeutic use using proof-of-concept human
laboratory testing. We believe this project will provide valuable insight into novel approaches for understanding
and treating alcoholism in the human population.

Publications
Publications are associated with projects, but cannot be identified with any particular year of the project or fiscal year of funding. This is due to the continuous and cumulative nature of knowledge generation across the life of a project and the sometimes long and variable publishing timeline. Similarly, for multi-component projects, publications are associated with the parent core project and not with individual sub-projects.
