LAB DESCRIPTION
LAB DESCRIPTION


Our lab is broadly interested in transmembrane and sesnory signaling based on channels, pursuing both biophysical mechanisms and bioengineering innovations.
Our research has been in the field of '''ion channels''', focusing on '''subthreshold or non-spiking behaviors''' and favoring concepts and methods from '''synthetic electrophysiology'''. Major interests are on in-depth biophysical mechanisms of ion channel functions, pursued by applying both biological and engineering principles onto biological entities (synthetic channel subunits & modulators etc.) and physical components (electrical & optical materials, devices, instruments, etc.) exogenously coupled with excitable membranes for the reconstitution of ion channels’ functionality & pathophysiology. We are particularly attracted by the amazing capabilities of ion channels in sensing exogenous stimuli of diverse modality, such as transmembrane potentials, ionic signals, mechanical forces and electromagnetic radiations. How exactly would ion channels sense, transduce and encode the stimuli (i.e., energy and information) at submolecular, molecular and cellular levels? Based on these core biophysics, we pursue mechanistic understanding, pathophysiological ramifications and bioengineering innovations, of '''transmembrane signalings''' via ion channels, especially those related to '''neural information processing''' (sensory functions and neural oscillations), and those crucial to '''neural plasticity''' (<math>Ca{_V}</math> channels and <math>Ca{^{2+}}</math> signaling).
 
The methodologies span from electrophysiology, biochemistry, molecular biology and optical imaging to biophysical modeling and engineering design & analysis.  
One of the most important signaling pathways to convey information from external world into biological systems is by way of channels sitting across the membrane. Such channels: could be cued either by physical (e.g. voltage or photons) or by chemical signals (e.g. small molecules or ions); could be either natural channels (e.g. ion channels conductive to Ca<sup>2+</sup> or K<sup>+</sup>) or engineered channels (e.g., nanopores by ultrasound). We mainly focus on fundamental mechanisms critical to channel complexes involved in transmembrane signaling, especially those related to sensory functions, such as vision and taste. Representative work toward this direction refers to [http://www.nature.com/nature/journal/v463/n7283/full/nature08766.html '''Liu X.''' ''et. al.'' '''Nature''']. Meanwhile, we actively explore the potentials of novel methodologies developped or derived from our basic research, such as sonoporation, channel modulators, biomolecular sensors etc. [http://openwetware.org/wiki/User:Xiaodong_Liu relevant publications]
