Research in the Swayne lab has made important contributions to understanding the cell biology of proteins that form channels (regulated doorways for ion and small molecules in cellular membranes). These contributions include the regulation of channel localization and function by intrinsic molecular elements, and protein-protein interactions, and the roles of channels and channel-regulating proteins in the development of neurons and cardiomyocytes. The Swayne lab’s current areas of focus are as follows:

  • The Swayne lab’s main CIHR-funded research project builds on the lab’s on-going work elucidating the role(s) of the Pannexin 1 (Panx1) channel protein in developmental and injury-triggered neuronal plasticity. The lab’s work in this area is currently focused on the role of Panx1 in regulating the formation of neuronal connections during early postnatal development. This work has important implications for neuropsychiatric disorders associated with the abnormal formation of neuronal connections.
  • In related projects funded by NSERC, the Swayne lab is unraveling the molecular mechanism regulating the localization of channel proteins in cells, including neurons.
  • In collaboration with Dr. Laura Arbour (IMP, UBC) the Swayne lab is investigating the cell biological underpinnings of clinically relevant ion channel mutations affecting First Nations patients affected by a spectrum of cardiac disease as well as seizure. The Arbour and Swayne labs have held two CIHR bridge grants for this work.
  • The Swayne lab is also collaborating with Dr. Caroline Cameron (Biochemistry & Microbiology), providing expertise in the study of protein-protein interactions and receptor biology to elucidate the molecular mechanisms underlying the invasion of Treponema pallidum, the bacterium responsible for syphilis, across the blood-brain barrier.

Swayne's lab receives new funding to better understand autism spectrum disorders and childhood stroke for research beginning in 2015.

Congratulations to PhD student Leigh Wicki-Stordeur for winning first prize, and to PhD student Andrew Boyce for honourable mention for trainee talks at the International Gap Junction Conference in Valparaiso Chile (March 28th-April 2nd 2015)!

Two students from Dr. Leigh Ann Swayne's lab received awards during Honours Fest held on February 28, 2014. Scott Bell received Top Presenter award for his poster entitled "Effect of Probenecid on the Neural Precursor Response to Stroke"and a one year membership in a professional membership of his choice.

Ross Prager received Best overall Honours Poster for all faculties with his poster entitled "Characterization of a novel Pannexin 1 channel internalization stimulus" and the "Boehm Family Award for Excellence in Science" plus $2000.

Scott (top) is pictured below with Dean Lipson from the Faculty of Science. Ross (bottom) is pictured with Dean Lipson and Associate Dean Kathryn Gillis from Faculty of Science. Congratulations to both of you for a job well done!

Dr. Leigh Anne Swayne has been awarded $98,000 for her proposal entitled "Preclinical Testing of Probencid for Stroke Recovery Treatment". Congratulations on your award and we look forward to seeing exciting results from your catalyst grant!

Despite the grey picture of massive cell death often accompanying stroke, the brain has a remarkable capacity for "recovery". Currently, we are largely unable to optimize this process of innate recovery and repair due in part to knowledge gaps in our understanding of the underlying cellular and molecular processes that modulate plasticity during stroke recovery.

There is an opportunity for you to become involved in this exciting area of research through a new graduate student position opening in the Swayne lab. Our relatively new lab has an excellent track record for publications and student scholarships. It is a stellar training environment both in terms of scientific training and career development and we are looking to recruit the best and brightest to join our research team.

If you are interested in applying, please send a CV and unofficial transcripts to Dr. Leigh Anne Swayne, .

Dr. Leigh Anne Swayne is creator and co-editor of a research topic published in Frontiers of Cellular Neuroscience. Read more.

Dr. Swayne and two of her graduate students, Leigh Wicki-Stordeur and Andrew Boyce recently had a paper published entitled Analysis of a pannexin 2-pannexin 1 chimeric protein supports divergent roles for pannexin C-termini in cellular localiztion. Read the abstract.

For her graduate studies in the Swayne Lab, Leigh Wicki-Stordeur has been selected to receive the following two awards from the Faculty of Graduate Studies Donar Awards. Leigh was awarded the Howard E. Petch Research Scholarship ($7500) and the Edythe Hembroff-Schleicher Scholarship ($9000). Leigh also awarded an NSERC PGSM earlier this year.

Congratulations Leigh and best wishes for continued success in your graduate program.
