Inhibition of Complement Regulators Sensitizes Tumor Cells to Complement Attack

Tumor cell lines resistant to complement attack overexpress membrane-bound complement regulatory proteins, limiting the efficacy of cancer immunotherapy. Researchers from Heidelberg, Germany, designed small interfering RNAs (siRNAs) to knock down these regulators and enhance complement-dependent cytotoxicity. They demonstrated that siRNA-induced inhibition of complement regulators significantly sensitized tumor cells to complement
