![Figure 8. Id+ B-lymphoma cells become annexin V+ when exposed to cloned Id-specific Th1 cells. Id+ F9 and Id- F55 B-lymphoma cells were incubated for 4 hours together with either an Id-specific Th1 cell clone (7A10B2), or magnetic bead–purified naive CD4+ T cells from a TCR-transgenic mouse (effector-target ratio [E/T] 2:1), followed by staining. Annexin-V staining of gated B220+ propidium iodide–negative lymphoma cells is shown as shaded histograms, open histograms represent annexin-V staining of lymphoma cells in the absence of T cells.](https://ash.silverchair-cdn.com/ash/content_public/journal/blood/102/2/10.1182_blood-2002-11-3381/6/h81434629008.jpeg?Expires=1722768170&Signature=GDpF16owvpy0GIWV7G7jXAl2eTDNoVbYuahwoZqUzEHLzs3kdFOZSudOxp-lWxHS6WcK--JvqAAFNkNoCamUH25-xY~8LVgFjEgnxXGMhQSxD~doVLhiuwX3KjIUhVLOBd~AFc69EKIwChz3GtEHieY4pSw1HZkBuvr3sbWVGx~VM5xtsjThMCcc-pnYjWMMPX5MwH1ZbNv-ewOM3nbptaX0qwPs4ZGMMssAHgkReO8Xaf5lr6JDsEj1hi8-ZCeIs7JVpmxEsjqMe0919AArmY7E1qd3VW~mW59rf7D0mvRg3KivR7r3vj0uIOHw15ZPnJxxiLDLAt3B9raKyOrVzQ__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
