General introduction
Prof. Xiao’s Lab has a long lasting interest in uncovering the function of glial cells in healthy and diseased brains, with a special focus on the biologyical behavior of oligodendrocytes (OLs) and their progenitors (OPCs), which is responsible for myelin plasticity/remodeling in both development and adult central nervous system (CNS) and is highly involved in a wide variety of brain diseases from demyelinating diseases such as multiple sclerosis (MS) to psychiatric disorders such as major depression and autism.
Prof. Xiao graduated from the Second Military Medical University (SMMU) and got his bachelor’s degree in medicine in 2002, and then Ph.D’s degree in neurobiology in 2007, under the supervisor of Prof. Yizhang Chen, member of Chinese Academic of Science. He was appointed associate professor of neurobiology in the institute of neuroscience in 2010 and worked as post-doctoral research associate in Bill Richardson’s (Fellow of Royal Society and Medical Science, UK) Lab in the University College London (UCL) from 2014 to 2016. He has published over 10 original articles in distinguishable biological journals such as Nat. Neurosci., JBC, Glia, Endocrinology and Mol Endocrinol. as first or corresponding author(s). His work has been cited by for over 1100 times. He has chaired 4 research funds from National Natural Science Foundation of China (NSFC), as well as many other projects. He has been selected as members of several talent scheme such as ‘Rising-Star in Science and Technology’ (Shanghai), ‘Support Program for Excellent Young Talent in Science and Technology’(General Logistics Department, PLA), Shanghai Pujiang program, and was awarded GSK-‘Tomorrow Start’ in neuroscience by the Chinese society of neuroscience together with GSK (China), as well as Young Neuroscientist in Yangtze River Delta .
Research interests
Glial cells make up roughly half of the total neural cells in the human brain. They have long been ignored simply as passive and supportive “glue” or “filling” elements for over a century since they were discovered. However, recent decades have witnessed a growing body of evidences showing the active involvement and important roles of glial cells in the normal function of central nervous system (CNS), as well as in various brain diseases. Thus, intensive studies on glial biology function is apparently needed to figure out how our brain works and allow a better understanding of many neurological and mental disorders that human beings have been suffering from.
Oligodendrocytes lineage cells, which consist of OLs and OPCs are the most abundant glial cells in the human brain and are responsible for the forming of myelin structure which wraps the neuronal axons that enables the saltatory conduction of the action potential and thus allow high efficiency transfer of neural information with in CNS. Recently, emerging studies including our own work have revealed an important role of adult new OL genesis and myelin formation in learning and memory. These findings argue for a critical supplementary mechanism of myelin plasticity in addition to the previously well-known synaptic plasticity underlying learning and memory.
Our team continuously aims to study the physiologic role of OL /OPC and myelin in brain function, as well as its involvement in various brain diseases. We take advantage of a combination of multiple experiment models including transgenic mice that allow manipulating and tracing of the new OL and myelin genesis or gene KO in OPCs in both developing and adult brain, as well as in vitro OPC culture or brain slices culture, human brain specimens, cuprizone induced mice demyelination etc. We also introduced in vivo multi-channel electro recording, optogenetics and calcium fiber photometry techniques to study the role of OL genesis/myelin plasticity in modulation of neural circuit activity. Specifically, our research directions include the followings:
l The physiological functions of OL and OPC, especially in the regulation of neural circuit activity.
l The key mechanisms for the failure of human CNS remyelination in demyelinating diseases and how to improve it.
l The role of OL and OPC in psychiatric disorders such as autism and depression.
l The glia-neuron interaction and (its)mechanism.
