USE OF THE PEPTIDE GK-1 EXPRESSED IN THE FILAMENTOUS PHAGE M13 FOR PREPARING PHARMACEUTICAL PRODUCTS THAT INCREASE THE EFFECTIVENESS OF THE IMMUNE RESPONSE INDUCED BY VACCINE ANTIGENS OR PATHOGENS
The present invention is directed to the use of FGK-1 immunopotentiator, composed by the peptide named GK-1, characterized by the sequence G-Y-Y-Y-P-S-D-P-N-T-F-Y-A-P-P-Y-S-A and linked to the pVIII surface protein of M13 filamentous phage, to prepare pharmaceutical products potentiating the protective immune response of vaccine antigens when used by itself or conjointly with these antigens administered either intranasally, subcutaneously, or intramuscularly, yielding an increase in the level of specific antibodies against vaccine antigens in serum and in bronchoalveolar lavages.
