This, the third volume of the Blood Cell Biochemistry series, follows the pattern estab- lished in the two previous volumes by containing up-to-date specialist reviews of topics of current interest within the field of study defined by the subtitle. Thus, the topics included can be loosely classified under the broad subtitle "Lymphocytes and Granulocytes," but this does not indicate the full scope of content, scientific interest, and emphasis of the present volume. The opening chapter, by Antonio Bonati, surveys the currently available bio- chemical, immunological, and molecular markers of hemopoietic precursor cells. This is followed, appropriately, by a contribution from Arnold S. Freedman on the cell surface markers in leukemia and lymphoma. In a detailed chapter, Annette Schmitt-Graff and Giulio Gabbiani discuss the cytoskeletal organization of normal and leukemic lympho- cytes and lymphoblasts. John C. Cambier and his colleagues then present a discussion of the signaling events in T-Iymphocyte-dependent B-Iymphocyte activation.
Lymphocyte IgE receptors and IgE-binding factors are dealt with by Kwang-Myong Kim and his colleagues, and the role ofgranule mediators in lymphocyte-mediated cytolysis is covered by John Ding-E Young and his associates. A short contribution from James D. Katz deals with the intricacies and difficulties of studies on the complement C3b (CRl) receptor and its cytoskeletal interactions in neutrophils. Arthur K. Sullivan then presents an in-depth survey of the membrane biochemistry surrounding the flow of granule organelles in leukocyte differentiation.
