Research Interests

The Xie lab studies satellite glia-neuron interactions in the peripheral nervous system. Satellite glial cells are the predominant glial cell type in the peripheral ganglia. They are in close proximity to ganglionic neurons, synapses, and vasculature. We have observed potent neuromodulatory capacity of satellite glial cells in physiology and diseases, such as modulating heart rate and contractility, blood pressure, and urinary output, and pain perceptions. Currently, the Xie lab utilizes conventional and state-of-the-art biomedical methods to study the mechanisms underlying satellite glia-neuron interactions, with a particular focus on how glia-neuron crosstalk alleviates chronic pelvic pain symptoms and improving cardiovascular functions. As one of the many research labs in the Basic and Translational Urology Research Program, we also work closely with other investigators in the program to train the next-generation biomedical researchers and clinicians.
