Research interests
My main research is focussed on the pathogenic mechanism responsible for ANCA associated vasculitis (AAV), and specifically on the pathogenicity of autoantibody specific for lysosomal associated membrane protein-2 (LAMP-2) (Kain et al., 2008) which are highly prevalent in those with AAV. Much of my work concentrates on the role of LAMP-2 in macro- and chaperone mediated autophagy since our current data suggest that both of these pathways are disrupted by autoantibodies to LAMP-2 and I am determining the extent to which this is responsible for their pathogenicity.
Techniques, methods & infrastructure
My expertise includes the broad range of methodologies required for contemporary cellular and molecular biology. These include cell culture, confocal microscopy, lived cells imaging, ELISA, immunoblot, immunofluorescence, PCR, real-time PCR, DNA and RNA analysis, generation of transgenic mouse. To apply these methods, I am using samples (tissue, serum, DNA, cell) from transgenic animal and human patients as well as in vitro models (cell culture).
