DSc (Hon Uni Athens)
Research in the Department has focused on a broad area which includes inflammation, post translation modification of proteins in age related macular degeneration (AMD), sepsis and the antiphospholipid syndrome (APS) , autoimmune disease, allergy and mast cell biology.
In the inflammation area we are examining the role of post translation modification of beta 2 glycoprotein (b2GPI) I and complement factor H (CFH) in AMD, gram negative sepsis and APS.
In the autoimmune area, animal experiments designed to elucidate the cause of thrombosis and miscarriage in women with the antiphospholipid syndrome. The assessment of Beta 2-glycoprotein I function in humans and experiments utilising b2GPI knockout mice (KO) that have been derived in the Department. Experiments looking at high fat diet and the role of b2GPI in modulating obesity using b2GPI KO mice.The role of oxidised and free thiol b2GPI and CFH in AMD, APS and gram negative sepsis.

The role of Beta 2-glycoprotein I in in-vitro and in-vivo angiogenesis is currently being investigated using a Matrigel and tumour animal models with Beta 2GPI knockout mice. The role of Beta 2GPI in cholesterol metabolism is being assessed using C57BL/6 Beta 2GPI+/+ and -/- mice fed a western diet.
