Abstract

The present invention relates to a polypeptide comprising a) a binding peptide binding to at least one protein selected from the group consisting of CD22, CD19, CD20, and CD21, and b) an immunogenic peptide comprising at least one T-cell epitope for use in vaccination of a subject against B-cell hyperproliferation or for use in the modulation of the immune response in a subject. The present invention further relates to a polynucleotide and a vector encoding said polypeptide and a host cell comprising the same. It also relates to a method for the stimulation of antigen-specific T-cells, comprising a) contacting antigen presenting cells (APC) with a polypeptide, the polynucleotide, or the vector of the invention, b) contacting said APC with T-cells, and c) thereby stimulating antigen-specific T-cells specific for said at least one T-cell epitope; to a method for immunizing a subject against B-cell hyperproliferation, to a method for immunizing a subject against an infectious agent, and to a method for inducing tolerance in a subject.
