Human Leukocyte Differentiation Antigen workshop Ⅴ / HLDA5

The Human Leukocyte Differentiation Antigen workshop Ⅴ (HLDA5), held in Boston, USA, in November 1993. Those present at this meeting represent the efforts of more than 500 laboratories worldwide who have jeoined together over a 2-year period to analyze 1,450 antibodies and characterize more than 150 molecules. Blind panels for all monoclonal antibodies (MoAbs) including every CD antigens, every known candidate for CD status, and all MoAbs of undefined specificity, were analyzed by flow cytometry. Other dedicated laboratories undertook serologic, molecular, biochemical,and histochemical characterization of the MoAbs and the structures they defined. The results obtained by all groups showed almost perfect concordance. Detailed results of these studies will be published separately. Based on these findings, the workshop organizers are pleased to recommend the adoption of 48 new CD clusters and subclusters and the redefinition of 14 previously established clusters. Table1 summarizes the additions and changes made to the existing CD nomenclature.
