Resistance to Interferon of a Human Adenocarcinoma Cell Line, HEC-1, and its Sensitivity to Natural Killer Cell Action

Abstract
A human endometrial cancer cell line, HEC-1, was resistant to the antiviral and anticellular action of interferon. HEC-1 cells were susceptible to the cytotoxicity of natural killer (NK) cells and interferon enhanced such NK activity. When HEC-1 cells were treated with interferon, sensitivity of HEC cells to the cytotoxicity of NK cells was not suppressed.
