IFN-gamma and IFN-alpha were potent inducers of HLA class I in all examined cell lines, with decreasing inducibility as follows: BT-20, ZR-75-1, MCF-7 and MDA-MB-468 cells. HLA class II (DR) antigen was highly inducible by IFN-gamma in ZR-75-1 cells, followed by BT-20, MDA-MB-468 and MCF-7 cells. IFN-alpha increased the cell surface expression of DR antigen only in ZR-75-1 cells. IL-1-alpha induced a moderate level of HLA class I antigen in ZR-75-1, BT-20 and MDA-MB-468 cells, and HLA class II (DR) expression only in ZR-75-1 cells. This pattern of cell line inducibility by IL-1-alpha was similar to that induced by TNF-alpha. Differences in inducibility of HLA antigens on human breast cancer cell lines induced by different cytokines may reflect the differences in cytokine inducibility of the original tumor cells."}
