Biophysical properties and functional roles of receptors and ion channels

Previous and Current Research

Prof. Zholos has long-standing interests in ion channel research and over 30 years of hands-on and supervisory experience in this area. This research employs patch-clamp recording techniques in combination with Ca2+ imaging and molecular biology approaches. It includes investigation of single ion channel mechanisms and the roles of multiple ligands in the regulation of novel TRP channels, as well as voltage-gated and receptor-operated channels in excitable and non-excitable cells.

Recent research highlights include identification of:

  • receptor-operated TRPC4 channels as the main molecular component of the muscarinic cation current in small intestine, which underlines cholinergic-excitation-contraction coupling in the gut;
  • molecular mechanisms of TRPC4 regulation and signalling;
  • enhanced expression and function of the heat and capsaicin receptor TRPV1 in severe bronchial asthma;
  • single-channel mechanisms of the cold and menthol receptor TRPM8 gating, as well as TRPM8 function in the vasculature;
  • biophysical and pharmacological characterisation of volume-regulated anion channels as an alternative pathway for chloride secretion in cystic fibrosis respiratory epithelial cells;
  • nanostructured materials (e.g. C60 fullerenes, carbon nanotubes) as novel modulators of BKCa and TRPC4 channels activity;
  • inhibitory action of general anaesthetics (isoflurane and ketamine) on the muscarinic cation current and carbachol-induced gastrointestinal smooth muscle contractions.

This research was funded by Ministry of Education and Science of Ukraine, Department of Targeted Education of Taras Shevchenko National University of Kyiv at the National Academy of Sciences of Ukraine, The Wellcome Trust (UK), British Heart Foundation (UK), National Institutes of Health (USA), NI Chest Heart & Stroke (Northern Ireland), Biotechnology and Biological Sciences Research Council (UK), The Royal Society (UK), The Physiological Society (UK), Mext (Japan), DEL (UK).

We have recently completed research project on ““Molecular and cellular mechanisms of TRP channelopathies” (2019-2021) and we are currently investigating “Transport of ions and oxalates as a key factor in chronic kidney disease and associated pathologies” (2022-2024).  Both projects have been funded by the Ministry of Education and Science of Ukraine. This research involves collaborations with clinical researches and institutes of the Academy of Sciences of Ukraine and the National Academy of Medical Sciences of Ukraine.

Future Projects and Goals

Ongoing research aims to develop and characterise novel activators and inhibitors of large-conductance Ca2+-activated potassium channels (maxi-K channels) and receptor operated TRP channels, which can be useful for the treatment of many disease states associated with either hyperactivity or reduced contractility of visceral and vascular smooth muscles, including pulmonary hypertension, irritable bowel syndrome, Parkinson’s disease, inflammatory colitis, disorders of uterus contractility, as well as chronic kidney disease.

Patch-clamp recording of Maxi-K channel activation by green laser-induced plasmon resonance (A) in an isolated arterial smooth muscle myocyte (B). In the cell-attached configuration, laser-illuminated AuNCs activate single Maxi-K channels in rat pulmonary artery myocytes in a remote manner (C).

Methodological and Technical Expertise

  • animal models of human disease, such as diabetes, Parkinson’s disease, and inflammatory colitis;
  • cell isolation techniques;
  • tensiometry for in vitro and in vivo recording of muscle contractile responses;
  • all variants of patch-clamp techniques (whole-cell and single channel recordings);
  • calcium imaging using CCD camera and confocal microscopy;
  • Ussing chamber for the investigation of ion transport and epithelial barrier function;
  • immunocyto/histochemistry, PCR and qRT-PCR;
  • data analysis using pClamp and MicroCal Origin software, custom programming:
