The role of an aggrecan 32mer fragment in developing osteoarthritis

Project Details

The proteoglycan aggrecan is a key component of the cartilage matrix, responsible for enabling weight bearing, by providing compressive relilience. Aggrecan is degraded in early osteoarthritis (OA) and we have evidence to suggest that a fragment of aggrecan, the ‘32mer’, might initiate the inflammation that leads to cartilge pathology. We have a project funded by the USA Department of Defense to investigate whether a monoclonal antibody that neutralises 32mer activity will alleviate OA following acute joint injury.
