A. Personal Statement
In the past decades I have been working in the field of brain-gut interactions and neurogastroenterology. We
have pioneered work on the central actions of peptides to influence digestive function, and developed this field
through continued competitive grants obtained from the National Institute of Health since 1982, including a NIH
Digestive Diseases and Kidney MERIT Award and Veteran Administration Merit Award. I have been mentoring
over 60 post doctoral PhD or MD fellows.

C. Contributions to Science
1. Define the biochemical coding and brain sites regulating gastrointestinal (GI) function under
physiological and specific pathological conditions. In the 1980’s as hypothalamic and gut peptides were
identified, my independent research provided the foundation for new insight to the role of neuropeptides in the
underlying coding of brain-gut interactions. I was the first to establish that bombesin, thyrotropin-releasing
hormone (TRH), somatostatin , gastrin releasing peptide corticotropin releasing factor (CRF), calcitonin gene
related peptide (CGRP), peptide YY, adrenomedullin urocortin 1, urocortin 2 the cytokine, interleukin-1β (IL1β and more recently, nesfatin-1 act in the brain to influence gastric secretory-motor function in rats or dogs.
Using peptides as novel tools to probe brain-gut interactions, we identified specific brain and spinal sites at
which these peptides and IL-1β act to influence GI function, namely the paraventricular nucleus of the
hypothalamus (PVN,), locus coeruleus complex, dorsal vagal complex (DVC, discrete raphe medullary nuclei,
or T9-10 spinal segment and characterized using electrophysiological, surgical and/or pharmacological
approaches the autonomic pathways and peripheral transmitters recruited by these brain peptides to exert their
influence on gastric acid, and mucus secretion, mucosal blood flow and motor functions.

2. Discovery that the three amino-acid peptide, TRH located in the brain medulla is the main
physiological stimulant of vagal outflow to the stomach independently from its pituitary action. In
particular we were the first to show that a) TRH injected into the cisterna magna or selectively into the DVC,
induces a vagal-dependent activation of gastric cholinergic myenteric neurons and motility, stimulation of the
gastric mucosal release of acid, histamine, serotonin, gastrin, ghrelin, mucus, and increased gastric mucosal
blood flow; b) the activation of raphe pallidus, raphe obscurus, or parapyramidal nuclei containing TRH
synthesizing neurons innervating the DVC, induces a vagal-dependent stimulation of gastric secretory-motor
function and elevation of circulating insulin which is mediated by endogenous TRH action onto DVC neurons;
c) brain medullary TRH mediates the vagal dependent stimulation of gastric acid induced by sham feeding,
and emptying induced by acute cold exposure; d) Using activation of TRH signaling pathways in the brain
medulla as a physiological probe to activate the vagus at different intensities, we unraveled the dual
gastroprotective or erosive impact of the vagus and peripheral mediators involved. A low level of TRH
receptor activation, elicited by exogenous or endogenous TRH in the DVC, induces a vagal dependent gastric
protection against experimental erosions brought about by the vagal dependent increase in gastric mucus
secretion, prostaglandin (PG)E2,- nitric oxide- and CGRP-dependent mechanisms including increased mucosal
blood flow while acid secretion is inhibited by the dual actions of PGE2 and CGRP. By contrast, maximal TRH
receptor activation in the DVC induces a vagal cholinergic dependent increased in histamine, gastrin and
related acid hypersecretion, along with sustained gastric motility response contributing to gastric erosions.
This brain medullary TRH pathway underlies cold exposure induced gastric erosions. These findings are
described in 92 publications in Pub Med.

3. Establish the role of brain and gut CRF receptor signaling in stress-related alterations of gut
motility and visceral hypersensitivity. This was shown by demonstrating that a) CRF and related peptides,
urocortins act at specific brain sites that alter autonomic outflow leading to inhibition of gastric transit and
motility; b) brain CRF signaling pathways is involved in the delayed gastric emptying induced by
psychological (restraint), immune (increased cytokines into the circulation or the brain), and visceral (surgery)
stressors; c) In the lower gut, the activation of CRF receptors in the PVN and coeruleus /subcoeruleus is
involved in the stimulation of colonic motor function through activation of sacral parasympathetic outflow; d)
this pathways has relevance in the defecation, diarrhea and visceral hypersensitivity responses induced
various acute or repeated psychological stressors. e) In addition to the brain, the gut is endowed with a CRFsignaling system that exerts a role as a local effector of the central autonomic pathways involved in the GI
response to stress. CRF/urocortins and CRF receptor subtypes including new isoforms were identified in layers
of upper gut and colon in rats and human tissues. Peripheral activation of CRF1 receptor was shown to
recapitulate key features of symptoms in diarrhea-predominant IBS, such as the stimulation of colonic
myenteric neurons, motility, defecation/watery diarrhea, visceral hypersensitivity to colorectal distention,
increased intestinal permeability in rodents.

4. Gut-Brain Peptides Signaling and the Regulation of Food and water Intake. An important aspect of gut
peptides is the regulation of their co-release depending upon the metabolic status. We identified a synergistic
interaction between leptin and cholecystokinin (CCK) to induce satiety in rodents exerted a the levels of
capsaicin sensitive vagal afferents. CCK and urocortin 1 also act synergistically to suppress food intake
through CRF2 receptors on gastric vagal afferents, a response that is lost in high-fat diet-induced obesity
