The calcium channel TRPV4 in skeletal development and arthritis

点击翻译按钮获取中文摘要

We have discovered that mutations in a calcium channel gene, TRPV4, cause an inherited osteoarthritis in the hands and feet. This work suggests that TRPV4 may be important in osteoarthritis and suggests the exciting possibility that modulating TRPV4 activity may provide a new therapeutic approach for arthritis. We will study how and why the mutations disrupt channel function and study mouse models to see if they are more or less susceptible to arthritis.
