TIG - Tolerance Laboratory
Professor Steve Cobbold (Senior Scientist)Steve Cobbold's Home Page
Steve is interested in the mechanisms of peripheral tolerance, and ways of generating tolerance as a therapeutic procedure. Most recently he has been working on identifying the molecular mechanisms of linked suppression and infectious tolerance. He has recently identified an important role for nutrient sensing, particularly of essential amino acids, and mTOR signalling as a mechanism of immune regulation and in the stability/plasticity of regulatory T cells.
He does quite a lot of analysis of T-cell subsets by up to 9 colour FACS, sorting and cloning, with Liz Adams (also you should see Steve if you wish to use the TIG FACSCalibur with 96 well plate autosampler facilities.)
Steve also recently corordinated a successful Departmental application for an ImageStreamX machine, which is essentially a high resolution fluorescent microscope combined with a flow cytometer, which can provide quantitative analysis of fluorescent images in up to 10 simultaneous colours and collect up to 2000 images per second with a resolution down to 0.3micron/pixel.
ImageStreamX Mk II multicolour images of dividing T lymphocytes.
He has also written various software for the lab, including a complete suite of sofware for SAGE (and microarray) analysis, some of which can be downloaded.
Jianguo Chai (Post Doctoral Scientist)Chai has recently joined our laboratory from Kings College, London. He has a lot of experience in murine skin graft models of tolerance and mechanisms of immune regulation. His primary focus is to continue the work on PARIS that was started by Giovanni Piotti and also the in vivo stability and epigenetics of Treg cells that was started by Robert Hilbrands.
