Monoclonal antibodies (mAb or moAb) are antibodies that are made by identical immune cells that are all clones of a unique parent cell. Monoclonal antibodies can have monovalent affinity, in that they bind to the same epitope (the part of an antigen that is recognized by the antibody). In contrast, polyclonal antibodies bind to multiple epitopes and are usually made by several different plasma cell (antibody secreting immune cell) lineages. Bispecific monoclonal antibodies can also be engineered, by increasing the therapeutic targets of one single monoclonal antibody to two epitopes.
CE7-specific redirected immune cells
Genetically engineered, CE7-specific redirected immune cells expressing a cell surface protein having an extracellular domain comprising a receptor which is specific for CE7, an intracellular signaling domain, and a transmembrane domain, and methods of use for such cells for cellular immunotherapy of CE7+ neuroblastoma are disclosed. In one embodiment, the immune cell is a T cell and the cell surface protein is a single chain FvFc:ζ receptor where Fv designates the VH and VL chains of a single chain monoclonal antibody to CE7 linked by peptide, Fc represents a hinge —CH2—CH3 region of a human IgG1, and ζ represents the intracellular signaling domain of the zeta chain of human CD3. DNA constructs encoding a chimeric T-cell receptor and a method of making a redirected T cell expressing a chimeric T cell receptor by electroporation using naked DNA encoding the receptor are also disclosed.
