For all those who are fascinated by the magic of the infinitely small, hidden in the bosom of the living being are millions of palpitating cells whose only demand for the surrender of their secret, and with it the halo of fame, is a lucid and tenacious intelligence to contemplate them, to admire and to understand them. - - - Ramón Cajal, 1923.

Curiosity drives the research in Zheng laboratory. Our work focuses on the signal transduction and cytoskeletal mechanisms that underlie axon guidance and regeneration, synapse formation and plasticity, and trafficking defects in neurodegenerative diseases. A major strength of our lab is the employment of advanced molecular/cellular imaging and manipulation approaches, which enable us to investigate spatiotemporally restricted signaling and cytoskeletal activities that govern and regulate a wide range of neuronal responses associated with neuronal development, function, and disorders. Our research goal is to provide a mechanistic understanding of the cell biology underlying these crucial developmental events, as well as to gain substantial knowledge on the molecular and cellular basis for brain abnormality and disorders.

Zheng laboratory is a part of the Department of Cell Biology, Emory University School of Medicine. We are also a member of Emory Center for Neurodegenerative diseases (CND). Physically, we are located on the fifth floor of the Whitehead Biomedical Research Building. Students and postdoctoral fellows in the lab receive not only basic training in developmental neurobiology, but also multidisciplinary skills, including primary neuronal culture, electrophysiological recording, high-resolution light & super-resolution microscopy, single molecular imaging and manipulation, whole brain imaging, and much more.  This is a very exciting time  for neuroscience as we start to get handles on many neurological disorders and diseases that have victimized human being for centuries.    It is also an exciting time for the laboratory. We are currently expanding and research positions are available! (view the announcement).  Interested persons should contact us directly.  

我们实验室坐落在美国乔治亚洲亚特兰大的埃默里大学(Emory University)的细胞生物系。 研究重点是集中在神经发育,疾病,和修复的细胞骨架和信号传导机理 (Cytoskeletal and signal transduction mechanisms). 现阶段主要研究神经发育过程中神经轴纤维的生长和导向(Axon growth and guidance), 神经连结的可塑性(Synaptic plasticity), 和胞内的运输缺陷 (trafficking defects)在神经衰竭性疾病 (neurodegenerative diseases), 包括老年痴呆症(Alzheimer’s Disease)中的作用. 我们的主要研究手段包括了各种细胞成像技术,从高分辨度高精度胞内离子成像和胞内微操作技术到脑片及活体成像。 我们的研究同时综合各类现代的细胞生物, 电生理, 和分子生物学技术来研究分子机制。
