Class I (alfa [a] and beta [b]) interferons (IFNs) are cytotoxic to melanoma cells. A, A375 melanoma cells were exposed to a dose titration of both class I and class II (gamma [g]) IFNs and assessed for cell death after 24 h. For (A) and (B), gray bars = total number of live cells and black bars = total number of dead cells, trypan blue positive. Error bars represent one standard deviation of the mean. B, MeWo melanoma cells were exposed to a dose titration of both class I and II IFN sand assessed for cell death after 24 h. Error bars represent one standard deviation of the mean.
