| Description | The interactions between integrins and their ligands rescue normal and neoplastic B cells from apoptosis in several ways. The first we have found that integrin stimulation enhances the amount of antiapoptotic proteins from the IAP family members. Second, to further control the levels of these proteins, integrins regulate their proteasomal degradation by controlling their level of ubiquitination. Indeed, the understanding of the well-defined mechanisms controlling apoptosis might provide future therapeutic strategies to modulate the survival of neoplastic B cells. |
