ABSTRACT:
A DNA-sequence comprising a first sequence coding for a native or mutant subunit of a bacterial toxin that confers enzymatic ADP-ribosylating activity, and a second sequence coding for a peptide such that the resulting fusion protein is in possession of water solubility and capability of targeting the fusion protein to a specific cell receptor different from receptors binding to the native toxin, thereby mediating intracellular uptake of at least said subunit;
fusion proteins coded for by such DNA-sequence;
compositions for use in improving immune functions; and
recombinant expression vectors and transformed bacterial cells containing such DNA-sequence.
