The Tybulewicz group

Immune Cell Biology Laboratory

The lab is studying signalling pathways that control the biology of B and T lymphocytes. In particular we are working on pathways that control lymphocyte activation, differentiation, survival, adhesion and migration. We use a broad range of techniques including cell biology, mouse genetics, biochemistry, imaging, proteomics, transcriptomics and cellular immunology. The lab currently consists of around 13 researchers including PhD students, postdocs and laboratory research scientists. For more information see the lab website.

Project summary

We have previously shown that the WNK1 kinase regulates T cell migration and adhesion (Köchl et al, 2016. Nat Immunol, 17, 1075-1083). In unpublished work we have found that WNK1 also regulates T cell activation and discovered a novel and unexpected signalling pathway that regulates ion and water flux across the plasma membrane, which is essential for T cell migration and activation, thereby opening up an exciting new area of investigation. The proposed research will focus on how the WNK1 pathway and ion and water flux regulate T cell migration and activation. The work will look at the role of ion and water transporters in the regulation of these processes, and is likely to use cell biology, imaging, mouse genetics, biochemistry, microfluidics and optogenetics.

Postdoctoral Training Fellows are expected to lead their own projects, contribute to other projects on a collaborative basis (both in the lab and with external collaborators) and guide PhD students in their research. The ability to work in a team is essential.
