In vitro study | The potency of Rituximab depends primarily on its complement-dependent toxicity (CDC), complement-dependent cytotoxicity (CDCC), antibody-dependent cytotoxicity (ADCC), and apoptosis-inducing effects. Rituximab induces the death of malignant B cells in vitro. The potency of the action varies with different target cells. In vitro, the cellular changes induced by Rituximab are: p38 MAPK, NF-κB, ERK1/2, inhibition of AKT anti-apoptotic, survival signaling pathways. Rituximab is highly effective in mediating complement-dependent toxicity (CMC) of different B cell lines and malignant B cells. The CD20 binding capacity of Rituximab was concentration-dependent. |
