New paper on anti-inflammatory effects of TRPV4 stimulation

11 January 2021

Prof Knight's research group have published a new study showing, for the first time, the anti-inflammatory effects of stimulating the mechanosensitive ion-channel, TRPV4, and its importance in cartilage health. Degenerative joint conditions, such as osteoarthritis, are associated with pro-inflammatory signalling which causes degradation of the articular cartilage leading to … [more]

The findings of this research study may help explain why cartilage breaks down with ageing or arthritis.

Research paper identifies the secret life of collagen

12 September 2017

Dr Gupta and Prof Knight have just published exciting results which cast light on how cartilage is able to withstand the demanding mechanical environment of the joint and may eventually help to explain why cartilage breaks down with ageing or arthritis. Collagen changes its crystallinity in response to physical forces, … [more]
