Figure 2. CD56+ DC stimulate T cells but do not lyse NK cell targets.
(A) Sort-purified circulating CD56+ DC were cultured with allogeneic T cells in an MLR and thymidine incorporation was determined on the sixth day. (B) CD56+ DC were tested in a standard chromium release lysis assay using K562 cells as targets. Data are representative of 3 separate donors.
