Abstract: The invention relates to a bispecific antibody targeting TfR1 and a soluble antigen. The inventors demonstrate that the unique mode of interaction of the bispecific antibody with TfR1 increases its persistence in vivo through an FcRn-like mechanism. It has been demonstrated on MCF7 cell line that the bispecific antibody induces soluble antigen (IL6) uptake through TfR1 mediated endocytosis. Effects of the bispecific antibody on XG6 cell lines viability have been demonstrated, notably on iron and IL-6 deprivation. Hence, the inventors design an improved sweeping antibody which can specifically target tumors and inflammatory cells expressing TfR1. By its unique mode of interaction with TfR1, its ability to induce soluble uptake antigen through TfR1 mediated endocytosis and its capacity to deprive cells of iron, known for being required in tumors growth and progression and development of inflammatory pathologies, the bispecific antibody can be used in the treatment of cancer and inflammatory pathologies.

Abstract: This invention provides novel erbB2-binding internalizing antibodies. The antibodies, designated F5 and C1, specifically bind to c-erbB2 antigen and, upon binding, are readily internalizing into the cell bearing the c-erbB2 marker. Chimeric molecules comprising the F5 and/or C1 antibodies attached to one or more effector molecules are also provided.

Abstract: This invention provides methods of selecting antibodies that are internalized into target cells. The methods generally involve contacting target cells with one or more members of an antibody phage display library. The members of the phage display library are also contacted with cells of a subtractive cell line. The target cells are then washed to remove the subtractive cell line cells and members of the phage display library that are non-specifically bound or weakly bound to the target cells. The target cells are cultured under conditions where members of the phage display library can be internalized if bound to an internalizing marker and internalized members of the phage display library are then identified.
