8th May 2017 – Human Leucocyte Antigen (HLA) System

Andy Canterbury is the business development manager for MC Diagnostics, a small company based in St Asaph, North Wales and they have developed a DNA microarray platform for medical diagnostic testing; the primary application being HLA typing. Andrew has an MSc in Immunology and started worked in the NHS as a clinical scientist, introducing DNA HLA typing into routine use. He then moved into the commercial world as a R&D scientist before progressing towards more business focused roles.

For your body to combat an infection, it requires a mechanism to distinguish what should be there ‘self’ and what is an invader ‘non-self’. This role is fulfilled by proteins on the cell surface of white blood cells, called Human Leukocyte Antigens (HLA). These molecules can present a major barrier to successful transplantation but by closely matching a patient and donor HLA, the risk of organ rejection is greatly reduced. The methods for HLA typing have developed over the years and today DNA based typing is routinely performed.
