| abstractText | BACKGROUND: Engineering a graft to secrete its own immunosuppressive antibodies may minimize the risks associated with current high dose systemic immunosuppression. METHODS AND RESULTS: A beta cell insulinoma cell line (NIT-1) was transfected with genes encoding a chimeric anti-CD4 antibody. The NIT-1 cells secreted functional chimeric anti-CD4 antibody that bound to the CD4 molecule on mouse thymocytes and inhibited in vitro proliferation of CD4+ve T cells. Both test and control transfected cell lines grew at a similar rate in immunodeficient mice. In immunocompetent NOD mice, NIT-1 cells are normally rejected by a cellular immune response against the SV40 T antigen. Although control transfected NIT-1 cells were rapidly rejected by NOD mice, anti-CD4 secreting NIT-1 cells grew significantly better and were able to form tumors at the site of injection. CONCLUSIONS: The local secretion of chimeric anti-CD4 antibody from transfected cells can contribute to graft survival in our transplantation model. |
