Scientists develop method to track immune system enzyme in live animals

Scientists supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) at the National Institutes of Health have created two mouse strains that will permit researchers to trace, in a live animal, the activity of an enzyme believed to play a crucial role both in the normal immune response as well as autoimmunity and B cell tumor development.

Natural immune-control system may aid treatment of autoimmune disease and tissue rejection

The immune system's ability to police itself may offer a new method of arresting the cells responsible for autoimmune diseases such as multiple sclerosis and for the rejection of transplanted organs and tissues, scientists at Dana-Farber Cancer Institute report in a study in the May issue of the journal Immunity.
