Gene therapy protocol at UCSD activates immune system in patients with leukemia
Date:2/11/2008

dentifying leukemia cells in patients with early disease, when the cancer otherwise might not be detected. It also provides a much more specific target for antibody therapy. Antibodies that target ROR1 would be unlike currently used antibodies, which bind antigens found not only on leukemia cells, but also on normal cells. Because they can destroy normal cells, the antibodies currently used to treat patients with this leukemia can cause side-effects and weaken the immune system.

The ROR1 antigen is ordinarily found on a few cells in early embryonic development and is not detected on adult human cells or tissues. However, high amounts of this antigen are found on all the leukemia cells of patients with CLL. In the PNAS paper, the UCSD researchers present data on the leukemia cells of approximately 70 patients, all of which expressed the ROR1 antigen.
