Research title: "The mechanisms of structural weakening of cartilage in
early osteoarthritis"
Description of proposed research:
Osteoarthritis eventually destroys the joint cartilage. However, before
visible cartilage loss occurs it weakens and becomes more vulnerable to
what would normally be safe levels of loading. Cartilage derives its
remarkable mechanical strength from a 3-D architecture of collagen
fibrils which actively constrains the proteoglycan component against
swelling in the presence of water. These two components cooperate to
create the excellent load-bearing characteristics of cartilage. The
eventual osteoarthritic destruction of cartilage is intimately tied up
with important changes in these two components and in their
interrelationship. Gaining an in-depth understanding of these changes
occurring during the early stages of the disease forms the basis of the
proposed investigation.
The research will seek to determine to what extent the spatial integrity
of the 3-D network of collagen fibrils, crucial to the effective
containment of the high swelling proteoglycans and therefore the loading
bearing ability of articular cartilage, is knitted into a coherent
structure by largely entwinement-based interconnections or by some form
of mediated linkage that is not entwinement based. If it can be
demonstrated that physical entwinement is a relatively unimportant
network linking mechanism this would place the focus on molecular agents
that would fulfil this crucial role of network linkage.
The research will have a strong micro and ultrastructural emphasis (SEM
and TEM) and the successful candidate will be working in a
biomechanics/biomaterials laboratory with a substantial history of
innovative cartilage research.
