Peter McCourt


Professor

Job description

Peter is teaching Biochemistry to Medical Laboratory Scientists and to Dental Nurses. He also supervises a number of PhD and MSc students. His current research involves developing super-resolution optical methods (SIM and dSTORM) for the study of liver sinusoidal endothelial cell (LSEC) fenestrations, and how they change with ageing. He is also studying endocytic processes in LSEC, and in their "cousins", bone-marrow sinusoidal endothelial cells.

    Research interests

    Currently studying receptors responsible for the clearance of hyaluronan, denatured collagen and other waste connective tissue molecules from the circulation by liver sinusoidal endothelial cells (LSEC). Also studying the bone marrow counterparts of these cells (BMSEC) in transplant studies with collaborators in Melbourne, Australia. Peter is also studying the effects of ageing on LSEC morphology, in collaboration with the ANZAC Research Institute, Sydney, Australia. To this end, Peter uses electron microscopy and super-resolution optical microscopy (SIM and dSTORM) to study LSEC fenestrations during the ageing process.
