Lisa Kilpatrick, PhD
Lisa Kilpatrick’s research has focused on brain signatures related to brain-body dysregulation in stress-sensitive disorders, including irritable bowel syndrome. In addition, she has a long-standing interest in the influence of sex on these signatures, and she regularly attends and contributes to the annual meeting of the Organization for the Study of Sex Differences. The exploration of sex differences in the mechanisms of treatment response is an important step towards optimizing cost-effective treatments for both men and women. In her role as a co-Investigator in the Bioinformatics Core, she will apply her advanced expertise on the analysis of resting state fMRI data, as well as other neuroimaging modalities, to implement the proposed neuroimaging analyses. She maintains this expertise through regular attendance at the Biennial Resting State Conference and Organization for Human Brain Mapping annual meeting, and she can quickly adapt to new developments in the rapidly-changing field of neuroimaging. In addition, she will lend her expertise in sex differences during the interpretation of the findings. She has collaborated with Drs. Gupta, Labus, and Mayer over the years and looks forward to contributing to this ambitious project.

Hon Wai Koon, PhD
Dr. Koon’s research is focused on the roles of antimicrobial peptide Cathelicidin in inflammatory bowel disease, intestinal infection and colon cancer. Cathelicidin is a natural endogenous anti-microbial peptide that is protective to host as a part of innate immune system. Dr. Koon’s laboratory was the first to show the anti-inflammatory effects of cathelicidin in C. difficile infection in mice and C. difficile toxin A and B in monocytes and macrophages. Cathelicidin mediates various anti-inflammatory signaling pathways that promote healing of intestinal mucosa. Such anti-inflammatory effects of cathelicidin may be protective to other acute and chronic intestinal inflammation. This involves the coordination of epithelial, endothelial and immune systems in intestine and establishes a new direction of research in digestive diseases across various functional systems in body.
Dr. Koon is also interested in the correlation of gene expression of cathelicidin and other antimicrobial compounds with the development of inflammatory bowel disease and other intestinal diseases.
Dr. Koon received Master and PhD degrees at the University of Hong Kong. He then completed his postdoctoral training in basic gastroenterology research at the Beth Israel Deaconess Medical Center of Harvard Medical School in Boston. He is Assistant Professor of UCLA Division of Digestive Diseases as well as a member of UCLA IBD Center and American Gastroenterological Association. Dr. Koon has a team of 3 undergraduate research project students, 1 postdoctoral fellow and 1 medical resident researcher. Dr. Koon’s projects are currently funded by NIH and CCFA grants.
Jason Kutch, PhD
Dr. Kutch’s laboratory is addressing the problem of chronic pelvic pain from a unique systems neuroscience perspective. He has a background in motor systems neuroscience, and have developed and published several non-invasive approaches to understanding muscle control in humans. They recently developed and published a new multimodal approach – including electromyography (EMG), functional magnetic resonance imaging (fMRI), and transcranial magnetic stimulation (TMS) – for revealing neural mechanisms of involuntary control of pelvic floor muscles. As the co-director of the neuroimaging working group in the NIDDK-funded multi-site Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network, he has played a leading role in the analysis of MAPP Phase I (2008-2013) fMRI data, and he currently plays a leading role in the design, implementation, and monitoring of the MAPP Phase II study (2014-2019). He leads MAPP research efforts to reveal brain imaging differences between pelvic pain patients and healthy controls, to predict longitudinal progression of pelvic pain symptoms from neuroimaging, and to stratify pelvic pain patients according to widespreadness of pain based on neuroimaging. In the proposed work, he will assist with the acquisition and analysis of novel 7T data to study sex related differences in patients with Irritable Bowel Syndrome (IBS).

Jeffrey Lackner, PsyD
I am Professor of Medicine and Chief of the Division of Behavioral Medicine whose clinical, research, and educational activities focus on the interplay of health and behavior. Since its founding in 1994, the division’s clinical arm provide brief, state-of-the-art treatment for patients with painful medical disorders. These disorders include irritable bowel syndrome (IBS), low back pain, pelvic pain, arthritis, fibromyalgia, non-cardiac chest pain, temporomandibular disorder (TMD) and benign headaches such as migraine and tension headaches. A unique feature of our clinical services is the use of evidence-based treatment protocols that help patients gain control of symptoms that have not adequately responded to standard medical therapies. Because our clinicians are active researchers, patients receive cutting-edge treatments often times before they are more broadly disseminated. Our clinical work emphasizes a collaborative approach that recognizes that each patient is unique and presents with specific problems and not simply a diagnosis or set of symptoms.
My research focuses on developing and testing novel and safe treatments for chronic pain disorders, understanding their “active ingredients”, identifying patients for whom they are most effective, and their real world value. With NIH support since 1999, my research has influenced clinical practice guidelines and established me as an internationally recognized authority in the behavioral treatment of chronic pain disorders particularly IBS.
Division research provides valuable scholarly experiences for trainees in the UB medical school, school of public health, and the College of Arts and Sciences. We are pleased to offer these educational opportunities to qualified students at other local and international educational institutions as well. Trainees learn to design, write, conduct and analyze quality research projects with the goal of co-authoring at least one empirical study for publication. The academic skills students learn during research rotation support their professional development whether they progress to careers as independent researchers or academically-oriented clinicians who depend on critical thinking and a scholarly approach to healthcare delivery.
As part of the division’s Clinical Research Consulting Lab, I routinely assist faculty and mentor residents and fellows in research design and methods and consult with industry partners seeking ways to harness the science of behavior change to gain a competitive edge for product development, strategy, and evaluation.

Muriel Larauche, PhD
Dr. Larauche research focuses on the modulation of visceral pain and colonic motor function by stress in rodents, with a special interest on the role of ovarian hormones and the gastrointestinal immune system, particularly mast cells. Her research activities also involve the development of new rodent models of visceral pain and stress. Her central hypothesis is that the higher susceptibility of females to visceral pain and constipation is related to sex-specific alterations of the immune (mast cells) and epithelial (ion channels and secretion, tight junctions and permeability) systems related to sex hormones. Dr Larauche intends to test her central hypothesis by pursuing the following specific aims. In Aim 1, she will dissect the role of gonadal hormones and sex chromosome complements in the sex difference in stress-induced visceral hyperalgesia and examine the influence of gonadal hormones on the recruitment and activity of colonic mucosal mast cells. In Aim 2, Dr Larauche will dissect the influence of sex chromosome and gonadal hormones on the sex- specific stress-induced alterations colonic epithelial permeability/secretion in female rats by assessing the modulatory effect of ovarian hormones on epithelial cells via tight junctions proteins modulation/permeability and on ion channels/secretion and on mast cells release of chymase and subsequent increase in angiotensin II leading to a reduction in ion secretion. Together, the proposed studies will enhance knowledge on interactions existing between sex and neuroimmune mucosal functions influencing pain sensitivity and secretion in IBS and enable the candidate to propose new testable hypotheses regarding mechanisms of IBS pain and constipation, in particular regarding differential treatment approaches based on pathophysiology and sex differences

Sheng-Xing Ma, MD, PhD
Sheng-Xing Ma is a Professor and Director of Integrated Medicine Research Laboratories at Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center. He was recruited to UCLA as an Assistant Professor in 1996, and he received a promotion to Associate Professor in 2003 and Professor in 2008 in the Department of Obstetrics and Gynecology at UCLA David Geffen School of Medicine and Harbor-UCLA Medical Center. Dr. Ma has been engaged in the studies of nitrate pharmacology, biochemistry and physiological effects of nitric oxide (NO) for the past 20 years. He has demonstrated that nitroglycerin modifies neuronal excitability, increases norepinephrine release/synthesis in heart and brain, and stimulates noradrenergic activation in the posterior hypothalamus, which contributes to nitrate tolerance and central cardiovascular effects of the drug. Results from his group have found that NO mediates acupuncture-induced cardiovascular and analgesic effects through a novel pathway, the dorsal medullar-thalamic tract. Another novel discovery is that NO-cGMP related biomolecules contribute to biochemical physiological changes in acupoints associated with meridian practices and diseases. He has developed a painless, non-invasive device to biocapture NO, cGMP, and nitrotyrosine from skin surface of acupoints and meridians for studies of signal transduction molecules during physiological and pathological changes, and therapies such as acupuncture, moxibustion, and meditation/Qi Gon.

Emeran A. Mayer, MD
Emeran Mayer is the director of the G Oppenheimer Center for the Neurobiology of Stress and Resilience (CNSR) at UCLA and co-director of the P30 funded CURE Digestive Diseases Research Center at UCLA. The CNSR is a NIH-funded, interdisciplinary and translational research center focused on brain gut microbiome interactions in 4 areas: Functional GI Disorders, Inflammatory Bowel Disorders, Ingestive Behavior/Eating Disorders, Chronic Visceral Pain Disorders. Within the CNSR, he has been the PI of a P50 SCOR grant from ORWH/NIDDK on sex-related differences in brain gut interactions with an emphasis on the effects of early adverse life effects on adult stress responsiveness and related brain circuits for the past 15 years. This grant has been successfully renewed over a total of three 5 year funding cycles under hisleadership. He is also the Co-PI of a UO1 grant focused on studying mechanisms of chronic pelvic pain (MAPP), now in its third 5 year funding cycle, and he leads the neuroimaging efforts within the consortium. Under his leadership, CNSR investigators have done pioneering work in applying psychophysiological and advanced brain imaging techniques to study the response of the brain to visceral stimuli in rodent models and human subjects with persistent visceral pain disorders, including IBS, IBD, IC/PBS and vulvodynia, to identify sex related differences in these brain responses, and to evaluate the effectiveness of pharmacologic and mind-based (including cognitive behavioral therapy) therapeutic approaches to some of these disorders. During the last 5 years, they have expanded their research efforts into the role of the gut microbiome in bidirectional brain gut interactions. They have pursued studies looking at the effect of altered autonomic nervous system output to the gut in altering gut microbial composition and function, and have been testing the hypothesis that gut microbial metabolites and inflammatory mediators in vulnerable patients can lead to neuroplastic changes in the central nervous system manifesting in persistent visceral hypersensitivity, cognitive decline and symptoms of autism spectrum disorders.
