Report on the fifth International Workshop on Human Leukocyte Differentiation Antigens

This paper represents a detailed description of the results and basic studies presented at the 5th International Workshop on Leukocyte Differentiation Antigen held in Boston on November 3-7, 1993. More than 500 institutions worldwide participated in the Workshop study groups, and approximately 1450 antibodies were investigated, allowing the identification of 48 new CD clusters and the redelineation of 14 previously clustered molecules . All the monoclonal antibodies (mAbs) were analyzed by flow cytometry and the data recorded in a Leukocyte Differentiation Antigen Database (LDAD), which represents the source of the information found in this workshop report. A more extensive account of this Workshop will be published by Oxford University Press before the end of 1994. The workshop was divided into 11 sections and the workshop organizers were the following scientists: Stuart Schlossman, Chairman of the Meeting, Laurence Boumsell (T-cell section), Wally Gilks (Statistical analysis), John Harlan (Endothelial cells), Tadamitsu Kishimoto (Cytokine receptors), Chikao Morimoto (Activation antigens), Jerome Ritz (NK antigens), Stephen Shaw (Cross-lineage blind panel), Timothy Springer (Adhesion section), Roy Silverstein (Platelets), Thomas Tedder (B cells), Robert Todd (Myeloid cells).
