Activated OT-I cells kill peptide-coated B cells, but are themselves killed by a CD95-dependent mechanism during this recognition process. 5 × 10⁵ previously stimulated (a and b) OT-I cells or (c and d) OT-I.lpr cells were cultured for 15 h with 5 × 10⁵ B6 plus bm1 B cells coated without (a and c) or with (b and d) 0.1 μg/ml OVA_257–264 peptide. The wells were then analyzed by flow cytometry using anti-B220–FITC and anti-K^b (5-F-1)–biotin followed by Streptavidin-PE.
