摘要
A modified peptide derived from matrix protein 2 (hereinafter also referred to as "M2"), one of surface layer proteins of influenza virus, and a method for utilization of the modified peptide are provided. A peptide (hereinafter also referred to as "M2eC peptide") that is made up by inserting cysteine residue(s) into a peptide (hereinafter also referred to as "M2e") consisting of 23 amino acid residues of from positions No. 2 to No. 24 of M2 in influenza virus type A, a fusion protein consisting of said modified peptide and a polypeptide, an influenza vaccine comprising said modified peptide or said fusion protein as an active ingredient, a device which can be delivered into the body comprising said influenza vaccine, a nucleic acid fragment consisting of a nucleotide sequence encoding the amino acid sequence of said modified peptide or said fusion protein, an expression vector in which said nucleic acid fragment is incorporated, a host in which said expression vector is introduced, and an antibody that has a protective effect against influenza virus.
