- the T cell epitope is originally used to induce antibody production against this epitope, so that antibody production against this T cell epitope is induced. Even so, it has already been confirmed that the side effects caused by it are not a problem, and therefore the safety of the peptide of the present invention is judged to be extremely high.
- RGD-IQMSDPAYNINISLP S YYPD- ⁇ -DAEFRHDSGYEVH which was prepared according to the method of Experiment 1, using ⁇ cell epitopes (MptL (43-62)) and A ⁇ (1 13) derived from Mycobacterium tuberculosis secretory protein ⁇ Dissolve 100 ⁇ g Zml of peptide having the amino acid sequence of SEQ ID NO: 37) and a, a ⁇ trehalose (reagent grade, sold by Hayashibara Biochemical Laboratories Co., Ltd.) in distilled water to a concentration of 40%, Sterilize by conventional methods To obtain a syrup agent.
- Example 2 Dilute the peptide prepared in Example 1 or Example 2 with physiological saline containing 0.5% sucrose so as to be 12.5 mgZml.
- LD was examined after oral, intraperitoneal, or intramuscular administration by conventional methods.
- LD is more than lOOmgZkg mouse body weight in terms of peptide mass.
- the peptide of the present invention is a safe preparation that is non-toxic even when administered to humans.
- RGD-FLQTMVKLFNRI KNNVAG- ⁇ -DAEFRHDSGYEVH (Sequence in the sequence listing)
- the present invention includes the vaginal cell epitope that has established immunological memory in humans and the amino acid sequence of the vaginal cell epitope possessed by amyloid ⁇ or a peptide containing the amino acid sequence, and the production of a specific antibody against ⁇
- peptide vaccine can be used as a peptide vaccine that induces antibody production against A ⁇ that is effective in preventing and treating various diseases such as diseases.
- the peptide vaccine of the present invention does not require the use of an immune adjuvant and can be used for transmucosal administration such as nasal administration or oral administration, it is simpler and safer than transdermal administration by injection.
- the present invention is an invention that exhibits such remarkable effects, and is a truly significant invention that makes a great contribution to the world.
