The reproductive hormones estradiol and progesterone bathe our internal organs. They have profound influence over the central and peripheral nervous system. While these steroids have been studied for many years, recent advances indicate that many actions of estradiol in the nervous system are mediated by receptors located on the cell membrane, suggesting more of a neurotransmitter than a hormonal role. My lab is working to understand the multiple mechanisms and circuits through which estrogen and progesterone affect cell types in different systems to affect reproduction, behavior, pain transmission and neuroprotection.

Research efforts in the Micevych laboratory involve understanding the cellular and molecular events underlying estrogen action on neurons and glial cells. Estrogen has profound effects on cognitive function and neuroprotection, as well as, reproductive functions. Estrogen affects the expression and activity of various neuropeptides and sex steroids. In particular they have focused on regulation mu-opioid and nociceptin receptors in the CNS regulation of sexual behavior. Recent experiments have demonstrated the synthesis of progesterone in the brain, its regulation by estrogen and physiologic functions of neuroprogesterone. RT-PCR and calcium imaging experiments in neurons and astrocytes have been used to elucidate the mechanisms of estrogen rapid signaling in both glial cells and neurons. The Micevych laboratory has demonstrated that estrogen can modulate nociceptive signaling through rapid actions on primary sensory neurons demonstrating a novel mechanism of estrogen modulation of pain. Additionally, the Micevych Laboratory has been studying the neuroprotective action of estrogen in the nigrostriatal dopamine system. Estrogen activates the insulin-like growth factor-1 (IGF-1) to ameliorate a hallmark of ParkinsonA?s disease A? the neurodegeneration of dopamine neurons. Significantly, estrogen or IGF-1 is efficacious after either central or peripheral administration. Together these experiments underscore the broad range of estrogen signaling influencing both physiology and pathology.

My research is focused on the derangements of the autonomic nervous system, especially the sympathetic nervous system, in humans with heart failure. I am currently studying the abnormal reflex responses to exercise in heart failure patients, and how these contribute to the overall exercise limitation in heart failure. We are testing the hypothesis that exaggerated sympatho-excitatory responses to exercise in heart failure are mediated by muscle mechanoreceptor sensory nerves, which have been sensitized by ischemic metabolites.…More

The development and assessment of nonpharmacological treatments targeted at chronic pain has also been a significant focus of my research. These include cognitive behavioral therapies as well as alternative medicine treatments of yoga and meditation. An important theme of this research is the use of both psychological and physiological measures (including autonomic assessment and brain imaging) to better understand the mechanism of change from non-pharmacological interventions and use of this information to guide better targeting of treatments to specific problems and individual phenotypes. My role Project Co-Leader for Project 3 in the current application involves working on the overall design, assessment protocols and application of the CBT treatment to interventional phenotyping. I have a long and close collaboration with Dr. Mayer, Dr. Chang and the other Investigators who will have my extensive background in behavioral, perceptual, psychophysiological and intervention research applied to chronic pain at their disposal throughout the study.

I am a Professor in the Department of Obstetrics and Gynecology and Director of the Pelvic Pain Clinic and the Vulvodynia research program and the PMDD research program at the University of California, Los Angeles. As an internationally recognized leader in the study of chronic pelvic and vulvar pain and hormonally mediated mood disorders I have authored or co-authored over a 120 articles, chapters, books, and reviews in this area. I have investigated peripheral and central mechanisms underlying pain and mood related to the reproductive system.

I am thoroughly versed in the literature and have very substantial clinical experience and a well-defined track record in the research and treatment of vulvodynia, pelvic pain, menstrually related mood disorders and menopause. I initiated one of the first multidisciplinary pelvic and vulvar pain clinics in the country. My goals were to offer comprehensive and innovative clinical care and access to current research studies for women suffering from complex chronic pelvic and vulvar pain disorders. Our UCLA site is also one of five research centers participating in the National Vulvodynia Patient Outcomes Registry thus far resulting in 4 publications with 1 under review.

I have collaborated with the investigators at the G Oppenheimer Center for Neurobiology of Stress and Resilience at UCLA for many years. If this proposal is funded, I will assist Drs. Chang and Gupta and their co- investigators with the conceptual and methodical aspects of the protocol concerning hormonal assessment and interpretation of menstrual cycle phase and post menopausal status and hormonal effects on GI symptoms, brain-gut microbiome, and gut transit. I will participate in the analysis and interpretation of all data and preparation and presentation of abstracts, manuscripts and reports. Given my clinical investigative experience working with this field, I believe I am well-equipped to be a significant contributor of the proposed research.

The “Brain in the Gut” and Taste Receptors

My research program is concerned with the neuronal circuits that control gastrointestinal motility and the mechanisms that govern receptor-mediated responses in the enteric nervous system, the “brain in the gut”, and with chemosensing in the gastrointestinal tract. Currently, the main lines of my research include: (1) trafficking and signaling of G protein-coupled receptors induced by physiological and pathophysiological events with an emphasis on µ opioid receptor, the target of opioid analgesics used for pain control, which mediates opioid bowel syndrome and tolerance, and (2) role of taste signaling molecules in the regulation of gastrointestinal functions and feeding behavior. My group was the first to demonstrate that opioids differing in their ability to induce tolerance also differ in their efficiency to induce µOR trafficking, a process that regulates receptor signaling and function. The findings of ligand-selective and stimulation-dependent µOR internalization in enteric neurons are of importance for understanding the mechanisms underlying intracellular adaptations induced by prolonged activation of µORs, which hamper the use of opioids as analgesics. Furthermore, we have shown that µOR activation exerts a protective effect on acute intestinal inflammation through cytokine and NF-KB modulation. Another focus of my research is on the role of taste signaling molecules as chemosensory receptors in the gut mucosa, which are likely to modulate gut function and food intake through the release of signaling molecules by enteroendocrine cells, with emphasis on bitter taste receptors, a putative side of defense from potentially toxic substances, drugs and pathogens. The recent discovery that taste receptors for sweet and bitter are expressed throughout the body and not only in the tongue has given rise to the concept of a broader role for these receptors beyond “taste”. My lab has shown that taste signaling molecules are expressed by distinct populations of mucosal cells, including enteroendocrine cells, which synthesize peptides affecting motility, secretion, satiety and hunger, and that bitter taste receptors are regulated by feeding and different diets, suggesting they participate in the functional detection of intraluminal content and they serve as regulators of diet-induced responses by detecting changes in the microbiota.
