A fusion protein for restoring functions of failing immune cells and application thereof. The fusion protein has a functional area for recognizing the failing immune cell and a functional area for conducting activation and amplification on the failing immune cell. The two functional areas are connected through a non-functional amino acid fragment with a certain length. The functional area for recognition uses the immune checkpoint specific antibody to recognize a phenotypic receptor of failing immune cells. The functional area for conducting activation and amplification adopts the cytokine or functionally-similar mutants, a ligand of the phenotypic receptor or functionally-similar mutants or an activating antibody to activate failing immune cells. The fusion protein recognizes failing immune cells, conducts activation and amplification on recognized failing immune cells, restores functions of killing antigen positive cells by the immune cells, and enhances inhibition of tumor growth and virus infection control.

An immunogen includes an isolated peptide of 800 amino acid residues or fewer having the amino sequence ILSAFSVYV (SEQ ID NO: 1) with four or fewer amino acid substitutions, a superagonist variant of SEQ ID NO: 1, or an amino acid sequence having the formula: (I/K/T/V/M)-L-(S/L)-(A/E/N/D/Q)-(F/V)-(S/M/V/I)-(V/D/R/G/H)-Y-(V/I/L) (SEQ ID NO: 13). The immunogens can be used in compositions and in the treatment of disorders.
