This thesis describes the development of a novel lectin-Fc fusion protein and its antiviral and anti-cancer activity. The molecule, Avaren-Fc (AvFc), is a fusion of a variant of the actinomycete lectin actinohivin (Avaren) and the Fc region of human IgG1, and is selective for the terminal α1,2-mannose residues found at the ends of high-mannose-type glycans that can be found on the surface of certain heavily glycosylated viruses and cancer cells. Here, AvFc was found to be able to neutralize simian immunodeficiency virus as well as Hepatitis C virus with nanomolar IC50 values. Furthermore, AvFc recognizes a number of cell …

Therapeutic antibodies are achieving new levels of therapeutic success in treating cancers and immunological disorders by antibody engagement of Fc receptor-directed immune responses. Conversely, inhibiting autoantibody induced Fc receptor activation is an attractive approach to treat autoimmune diseases. Immunoglobulin G (IgG) antibodies are often the principal subclass used in therapeutic antibodies and associated with autoimmune pathologies because of their long circulation and potent effector functions, including activation of the Fcγ Receptor (FcγR). Thus, a thorough understanding of the FcγR activation is required to improve the efficacy of immunotherapies and to mitigate autoimmunities. It is well established that FcγR clustering is …
