Exosome-induced apoptosis of CD8⁺ Jurkat cells. (A) Representative flow cytometry data for Annexin V-stained CD8⁺ Jurkat cells incubated with exosomes or PBS as control for 24 h. (B) Cumulative data from experiments in which CD8⁺ Jurkat cells were co-incubated with increasing protein levels of exosomes isolated from supernatants of HPV(+) or HPV(−) cell lines or with lysates of these cell lines.
