Summary of Current Research

My laboratory investigates transduction and signaling by somatosensory primary afferent neurons. We use patch clamp recording, immunofluorescence, molecular biology and functional imaging techniques to study ion channels which are responsible for the transduction of chemical, mechanical and thermal stimuli. We also investigate how ion channels are modulated by inflammatory mediators. These studies are important for a better understanding of the cellular mechanisms that are involved in sensory transduction and primary hyperalgesia. In addition, we utilize two approaches for studying peripheral neural mechanisms of chronic pain. One approach focuses upon the biophysical, pharmacological and immunohistochemical characteristics of neurons obtained from diabetic animals and patients treated by ganglionectomy for intractable pain due to nerve injury. A second approach utilizes microneurographic recordings in patients with trigeminal neuralgia or complex regional pain syndrome. These more clinically oriented studies seek to elucidate the cause of abnormal action potential discharge in injured neurons.
