Hu14.18-IL2 Fusion Protein

Definition 1

A recombinant protein consisting of the hu14.18 monoclonal antibody fused to the cytokine interleukin-2 (IL2) with potential antineoplastic activity. The monoclonal antibody portion of the hu14.18-IL2 fusion protein binds to tumor cells expressing the GD2 antigen (melanoma, neuroblastoma and certain other tumors); the Fc component of the fusion protein antibody moiety and natural killer (NK) cells mediate antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cellular cytotoxicity (CDCC) towards GD2-expressing tumor cells. The localized IL2 moiety of the fusion protein stimulates NK and T-cell antitumor cellular immune responses. (NCI Thesaurus)

Definition 2

An anticancer drug in which hu14.18, a monoclonal antibody, is combined with interleukin-2. The monoclonal antibody binds to the cancer cells and delivers IL-2, which stimulates the immune system to destroy the cancer cells. (NCI Dictionary)
