Abstract
Fc receptors are important for the clinical efficacy of therapeutic antibodies. Bispecific antibodies (BsAb) are immunoglobulin-conjugates with two different binding specifities, targeting tumor antigens and effector cell trigger molecules. BsAb, produced by chemical coupling of one antibody against a tumor cell surface antigen with another against a Fc receptor, mediate effective interactions between effector and target cells.
Highlights
HLA DR-directed bispecific single-chain Fv antibodies for lymphoma therapy Y Wachter*, J Brünke, S Schuster, K Barbin, M Peipp, T Valerius, M Gramatzki, G Fey and R Repp
HLA class II and Lym-2 are both known as effective targets for effector cell-mediated lysis of malignant human B-lymphoid cells
Recombinant scFv against HLA class II, Lym-2, CD89 and CD16 were obtained from the hybridomas F3.3, Lym-2, A77 and 3G8 respectively
