Physiology and Pharmacology of Ligand-Gated Ion-Channel Receptors
These important receptor ion channels help control fast communication in the nervous system and play a part in a wide range of diseases and conditions such as epilepsy, anxiety, depression, sedation, irritable bowel syndrome and pain. Stephen's laboratory uses state-of-the art patch-clamp electrophysiological recording to try to answer questions about these receptor ion channels. This is also complemented by biochemical techniques such as SDS-PAGE /western blotting and RT-PCR. Recently they have be using the Odyssey imaging system to look at both expression of intracellular proteins and cell surface expression of receptors in the ‘in-cell western’ and ‘on-cell western’ techniques.
Recently, in collaboration with Claire Peppiatt-Wildman and Scott Wildman, the group have begun looking at the role of GABAergic modulation of kidney function. Although GABA and its synthesising enzyme, glutamic acid decarboxylase, have been identified in the kidney and physiological concentrations of GABA are measurable in urine, little is currently known of the precise physiological role that GABA plays in kidney function or its potential as a therapeutic agent in renal pharmacology.
The group is actively engaged in defining the role of GABA and GABA receptor subtypes in the kidney utilising a state-of-the art techniques that can assess real-time functional changes such as patch-clamp electrophysiology and an intact-kidney slice model combined with biochemical techniques such as SDS-PAGE and immunoblotting.back to top
