Research Interests

My research interests focus on the central mechanisms of pain transmission and analgesia. Pain is a hallmark of tissue damage and inflammation, which promotes tissue protection and thereby contributes to repair. Thus, transient acute pain is an important feature of the adaptive response to damage. However, pain can persist for months to years after surgery even though the surgical incision that originally caused the pain has recovered. Such chronic neuropathic pain is maladaptive because it no longer serves as a protective reaction. Chronic pain, especially chronic neuropathic pain, is debilitating, both physiologically and psychologically, and treatments to provide relief from chronic pain are often ineffective. To date, the neurobiological mechanisms that underlie the transition from adaptive acute pain to maladaptive chronic pain are not fully understood. Chronic postsurgical pain provides a special opportunity to understand pathogenic mechanisms for the transition from an acute to a chronic pain state. Previous studies have shown that psychosocial and socio-environmental factors are involved in the development of chronic postsurgical pain. My laboratory combines plantar incision with stress to investigate the pain transition process after surgery. We hypothesize that stress induces the transition from acute to chronic postsurgical pain through stress hormone-produced regulation of AMPA receptor function. This research proposal has been funded with a 5-year NIH R01 grant. In this project, we will demonstrate the molecular mechanism by which stress induces pain transition after surgery. Our data will help physicians predict which patients are at greater risk for developing chronic pain after surgical procedures. Eventually, monitoring of stress hormone levels in the blood may improve pain management in high-risk patients.

Recently, my laboratory has developed a new line of research to unveil the antinociceptive effect of motor cortex stimulation (MCS) using optogenetics. MCS has been used since 1991 to treat chronic neuropathic pain. Electrical stimulation of the primary motor cortex (M1) has been demonstrated to suppress neuropathic pain in different animal models. In the clinic, use of invasive electrical or non-invasive transcranial magnetic stimulation of M1 has been reported to alleviate intractable chronic pain. However, the mechanisms underlying the antinociceptive effect of MCS remain poorly understood. The recent development of optogenetics, a revolutionary research tool, combines the delivery of light with specific wavelengths (opto) with the introduction of genes encoding for light-sensitive transmembrane channels (genetics) and makes possible highly precise spatial and temporal control of specific neuronal populations. In this project, we will utilize optogenetic manipulation to investigate MCS-induced descending pain control.
