A contributing factor to the development of arthritis is the inappropriate proteolytic destruction of the aggrecan component of cartilage by the proteolytic enzyme aggrecanase. The immune system signal molecule interleukin 2 (IL-2) activates aggrecanase; in fact, IL-2 blockers are sometimes used to treat arthritis. Studies were undertaken to determine whether inhibitors of aggrecanase could counteract the effects of IL-2. Pieces of cartilage were incubated in media with various additions and the amount of aggrecan destruction was measured as a function of time. What is the effect of adding IL-2 to the system? Aggrecan degradation remains the same. Aggrecanase activity is greatly reduced. Aggrecan degradation is greatly reduced. Aggrecan degradation is greatly enhanced. What is the response when an aggrecanase inhibitor is added in addition to IL-2? O Aggrecan degradation remains the same as when IL-2 was added. Aggrecan degradation completely stops. Aggrecan degradation is reduced to…
