A Fas agonist induces high levels of apoptosis in haematological malignancies
Journal Article --- Old month value: Apr
We developed and tested a potent hexameric Fas agonist, termed MegaFasL, for its cytotoxic effects on a panel of human haematopoietic malignant cells and healthy human haematopoietic progenitor cells (CD34+CD38low). Results demonstrated that MegaFasL induced apoptosis in cell lines and primary cells representing multiple myeloma (MM), acute myeloid leukaemia (AML), acute lymphoblastic leukaemia (ALL) and Burkitt's lymphoma. Cells from a chronic myeloid leukaemia (CML) line and from patients with chronic lymphocytic leukaemia (CLL) were resistant. Furthermore, CD34+CD38low progenitor cells were also resistant to MegaFasL. The data indicate that MegaFasL could be a highly efficient therapeutic agent ex vivo or potentially in vivo.
