    • 6 cells). For cell adhesion studies, neutrophils were placed into flat-bottomed 96-well plates coated with fibronectin (10 μg/ml), and the percentage of adherent cells relative to input was determined by XTT assay (Boehringer Mannheim). FcγR-mediated phagocytosis of neutrophils was measured with Fc-OxyBURST reagents (Molecular Probes, Eugene, OR). Chemotaxis assays were carried out with 24-well Transwell chambers (8.0 μm).

    • Immunocytometry was performed as follows. Cell suspensions of thymi, lymph nodes, bone marrow, blood, and spleens were stained with fluorescein isothiocyanate (FITC)-, phycoerythrin (PE)-, or biotin-conjugated antibodies to cell surface molecules. For the analysis of thymocyte precursors, cells were stained with PE-conjugated anti-CD4, anti-CD8, anti-CD3ε, anti-B220, anti-CD11b, anti-Gr-1, and anti-TCRγδ; FITC-conjugated anti-CD25; and biotin-conjugated anti-CD44. PE-negative precursor cells were analyzed for expression of CD25 and CD44. Biotinylated antibodies were visualized with streptavidin-RED670. Samples were analyzed by FACScan.

    • 6 cells/ml in Iscove's modified Dulbecco's medium (10% fetal calf serum) and treated with apoptotic stimuli. Cells were harvested; stained with the 7-amino-actinomycin D (7-AAD), anti-CD4, and anti-CD8; and subjected to fluorescence-activated cell sorting (FACS) analysis. Apoptosis was confirmed with annexin V, propidium iodide, trypan blue, and 3,3′-dipropyloxacarbocyanine iodide.

    • 51Cr release was calculated as [(experimental release - spontaneous release) X 100/(total release - spontaneous release)]. For hapten immunization, male mice were intraperitoneatty immunized with 100 μg of the T cell-dependent haptenated protein NIP-OVA. NIP-specific IgG1 titers were determined by enzyme-Linked immunosorbent assay (ELISA) on plates coated with NIP-bovine serum albumin.
