METHOD FOR PREVENTION OR TREATMENT OF ONE OR MORE OF DISEASES RELEVANT TO THE PROTEIN IN THE PROTEIN-CELL CONJUGATE, MALIGNANT TUMORS, INFECTIOUS DISEASES CAUSED BY PATHOGENIC MICROORGANISMS AND AUTOIMMUNE DISEASES
The present invention pertains to immunology, biomedicine field, specifically relates to a method for prevention or treatment of one or more of diseases relevant to the protein in the protein-cell conjugate, malignant tumors, infectious diseases caused by pathogenic microorganisms and autoimmune diseases. The method includes a step of administering to a subject in such need a prophylactically or therapeutically effective amount of a protein-cell conjugate, the said protein-cell conjugate is a conjugate formed by covalently linking a protein and a cell to a linker, respectively the cell has free sulfhydryl groups distributed on its surface, when the cell is not linked to the linker the linker is derived from a bifunctional cross-linking agent, and the bifunctional cross-linking agent comprises both a group capable of reacting with an amino group and a group capable of reacting with a sulfhydryl group.
