On page 508 of this article, “alemtuzumab (a monoclonal antibody directed against CD25 (also known as interleukin-2 receptor subunit-α), which is expressed on leukocytes)” should have read “alemtuzumab (a monoclonal antibody directed against CD52, which is expressed on lymphocytes)”. This has been corrected in the online version.
