ABSTRACT Considering variable and often modest therapeutic efficacy of Rituximab for a substantial proportion of patients suffering from Non-Hodgkin lymphomas (NHLs), various type II anti-CD20 monoclonal antibodies (mAbs) with excellent ability in inducing programmed cell death (PCD) are developed for enhanced therapeutic index currently. Although homotypic adhesion (HA) and lysosome leakage are proved to be of vital importance in type II mAb induced PCD in NHL cells, the detailed relationship between them remains unclear. Herein, for the first time we discovered that the improved intracellular ceramide level is an important mediator between HA and lysosome leakage in Tositumomab induced cell death. Further experimental results revealed that the generation of intracellular ceramide acts as the outcome of HA and major cause of lysosome leakage. The clarification of ceramide involvement in type II anti-CD20 mAb induced PCD may provide new ideas in CD20 based immunotherapy against NHLs.
