Profile

Research: Regulation of the Transcription Factor NFAT5

Dr. Zhou’s laboratory is primarily focused on signaling regulation of NFAT5 in hypertonic stress and leishmaniasis. NFAT5 is the newest member of the Rel transcription factor family. It regulates a variety of biological functions. Its protective role against hypertonic stress and modulation of immune responses are the two areas which have been studied most. The kidney medulla is normally exposed to a hypertonic environment because of the urinary concentration mechanism. NFAT5 is essential for the kidney medulla to survive and function adequately.  NFAT5 may also protect against the pathogenic effects of parasites. like Leishmania. Over the past decade, more than a dozen of kinases have been identified that involve in tonicity-dependent activation of NFAT5 in cell culture. The opposite role of phosphatases has recently begun to reveal. Dr. Zhou’s laboratory is using cell and molecular approaches and mouse models to study how kinases and phosphatases regulate NFAT5 in the macrophages and kidney medulla from the normal mice and mice infected with Leishmania.
