We tested whether a peptide ( BCR1/25 ) encompassing the fusion region of the hybrid molecule pml/RAR alpha , which is selectively expressed by acute promyelocytic leukemia (APL) cells , can be recognized by human T lymphocytes in vitro.
 ( cell type: T lymphocytes, None) , ( cell type: acute promyelocytic leukemia (APL) cells, None) , ( cell type: human T lymphocytes, None) , ( protein: fusion region, None) , ( protein: pml/RAR alpha, None)
