Abstract: The construction, expression and secretion of two genetically engineered antibody-cytokine hybrid fusion proteins is described. To target tumor necrosis factor (TNF) to tumor cells, recombinant antibody techniques were used to generate F(ab')2-like antibody-TNF fusion proteins. At the gene level, an antitransferrin receptor antibody heavy chain gene was linked to a synthetic gene coding for human TNF. The chimeric heavy chain-TNF genes were introduced into a light chain secreting transfectoma cell line, which was producing the light chain of the same antibody. Cell lines were isolated which secreted antibody-TNF fusion proteins of expected size and composition. Culture supernatant of these cell lines contained TNF cytotoxic activity towards murine L929 cells and human MCF-7 cells, indicating that TNF is still active in the fusion protein constructs. These results illustrate the feasibility of the antibody engineering technology to create and produce chimeric mouse-human immunotoxin-like molecules. Furthermore, they demonstrate the ability of mammalian (myeloma) cells to express and secrete antibody-cytokine hybrid molecules with potential use in anticancer therapy.
