Michael Gold, PhD
Professor

Pain continues to be a major health problem with tremendous financial, social and psychological costs. Conservative estimates put the cost of pain to the US economy well into the hundreds of billions of dollars per year as a result of associated medical expenses and lost wages with a significant minority of Americans suffering from persistent or recurrent pain syndromes throughout the most productive years of their lives. Just one pain syndrome, migraine headache, directly impacts 20% of the adult population. Yet, there remain few if any effective therapies devoid of serious side effects that are currently available to treat pain, particularly persistent or recurrent pain associated with syndromes.

The clinical features of a number of pain syndromes serve as the organizing focus of research in the Gold laboratory. These observations include the following: 1) many pain syndromes are unique to a particular part of the body such as the head in migraine, the temporomandibular joint in temporomandibular disorder (TMD), or the colon in inflammatory bowel disease (IBD); 2) many pain syndromes such as migraine, TMD and IBD occur with a greater prevalence, severity and/or duration in women than in men; 3) many pain syndromes are associated with changes in the excitability of primary afferent neurons; 4) there are time-dependent changes in the mechanisms underlying pain syndromes; and 5) the type of injury, (i.e., inflammation or nerve injury), are differentially sensitive to therapeutic interventions. These observations led to specific hypotheses that are tested in ongoing studies in the Gold laboratory. These include 1) characterizing the mechanisms underlying inflammation-induced changes in the evoked Ca2+ transients in sensory neurons, 2) characterizing the mechanisms underlying the initiation of migraine attacks, 3) characterizing the influence of estrogen on the excitability of spinal and trigeminal ganglion neurons, 4) characterizing the role of changes in inhibitory receptors, in particular GABA, in injury-induced increases in sensitivity, and 5) identification of ways to maximize the therapeutic utility of local anesthetics. The ultimate goal of these studies is to identify novel targets for the development of therapeutic interventions for the treatment of pain.

Co - Director, MSTP

Our laboratory is interested in identifying new molecular pathways in epithelial biology in the pathogenesis of tissue remodeling in chronic obstructive lung disease (COPD) and pulmonary fibrosis to improve therapeutic options for patients. Our lab specifically studies the role of adenine nucleotide translocase (a canonical mitochondrial ADP/ATP transporter) in the airway and alveolar epithelium of the lung in the context of cigarette smoking-related lung disease and lung fibrosis. We want to better understand how in health and disease ANT regulates epithelial function through cell metabolism and cellular senescence, as well as, airway epithelial homeostasis through surface hydration and the action of tiny motile cilia in the airway. We utilize a repertoire of relevant murine models of injury, molecular genetic approaches, in vitro biochemical assays, and human bio-samples to examine epithelial cell homeostasis in the lung.

We further pioneered and apply patient-derived 3D Lung Tissue Cultures that allow to further validate and test potential novel drugs in an individualized fashion.
