Abstract
The synthetic peptide disclosed herein is a synthetic peptide which is artificially synthesized for suppressing binding of CTLA4 to at least one of B7 proteins B7-1 and B7-2. The synthetic peptide includes a CTLA4-B7 protein binding inhibitory peptide sequence. The CTLA4-B7 protein binding inhibitory peptide sequence is any one of amino acid sequences shown in the following (1) to (3): (1) a TIM3-SP-related sequence; (2) an LAGS-SP-related sequence; and (3) a CTLA4-SP-related sequence. Here, the total number of amino acid residues in the above-described synthetic peptide is 100 or less.
