Abstract : "FasL belongs to the TNF family and interacts with the “so-called” death receptor Fas to trigger apoptosis. FasL is a transmembrane ligand, which can be cleaved by metalloproteases to release a soluble factor. While the membrane-bound FasL is a potent inducer of apoptosis, its soluble counterpart fails to induce cell death but trigger pro-inflammatory signals promoting the migration of triple negative breast cancer cells. More recently, we found that the loss of Fas in TNBC cells engenders a potent pro-inflammatory NF-kB signaling pathway, which promotes the elimination of the cancer cells via the activation/recruitment of anti-tumor NK cells. Because Fas expression is maintained in breast cancer cells isolated from TNBC patients and is associated with a good prognosis, we now aim at identifying in a comprehensive manner the Fas-dependent molecular mechanism controlling NF-kB in these TNBC cells."
