Cilia Mechanosensation

B1 integrins (green) are present on the chick chondrocyte cilium (red).

It is well established that mechanical loading is essential for maintaining healthy articular cartilage - the tissue affected in osteoarthritis.

The cells present in cartilage sense and respond to mechanical changes in our joints and regulate the production of extracellular matrix, the structural molecules that give cartilage its resiliency.

However, exactly how the cells sense these changes remains unclear. We believe that the primary cilium acts as a cellular antenna, sensing changes within cartilage tissue and sending important signals back to the cell.

This project investigates whether primary cilia act as biosensors and are involved in the signalling processes that regulate the production of extracellular matrix.
