In the article by Romano et al, entitled “Triggering of CD40 Antigen Inhibits Fludarabine-Induced Apoptosis in B Chronic Lymphocytic Leukemia Cells,” which appeared in the August 1, 1998 issue, volume 92, no. 3, pp 990-995, a correction should be noted. The name of a coauthor was misspelled. Instead of Patrizio Bonelli, it should be Patrizia Bonelli.
