Provided is a pharmaceutical composition, including an antigen fusion protein which includes an antigen and an antagonist of an Fc gamma receptor. Also provided is a method of enhancing immunogenicity of an antigen, including conjugating the antigen with an antagonist of an Fc gamma receptor to form an antigen fusion protein. Also provided is a method of enhancing an immune response to an antigen in a subject, including administering to the subject an effective amount of an antigen fusion protein which includes an antigen and an antagonist of an Fc gamma receptor. The present invention may be applied in the development of potent vaccines based on targeting vaccine antigens to antigen-presenting cells via binding to Fc gamma receptors.

Compositions and methods for enhancement of immune responses

Described herein are an immunogenic peptide containing the sequence of CLDSLGQWN (SEQ ID NO:2) and a method of using the peptide for treating cancer.

Immunogenic peptide containing a b cell epitope of tumor associated antigen L6

A composition in a water-in-oil-in-water (W/O/W) emulsion is disclosed. The composition comprises: (a) a continuous aqueous phase, comprising HO; (b) an oil phase or an oil shell, dispersed in the continuous aqueous phase; and (c) a hydrophilic polymer, stabilizing an interface between the continuous aqueous phase and the oil phase or the oil shell to form the water-in-oil-in-water (W/O/W) emulsion. The oil phase or the oil shell comprises: (i) oil; (ii) an internal aqueous phase, dispersed within the oil or the oil shell; and (iii) a lipophilic sorbitan-polyester conjugate, stabilizing an interface between the oil and the inner aqueous phase to form a water-in-oil (W/O) emulsion. The lipophilic sorbitan-polyester conjugate comprises: (1) sorbitan; and (2) poly(lactide-co-&#x3b5;-caprolactone) or polylactic acid (polylactide), conjugated to the sorbitan.
