Abstract

The application provides a double-signal activated carrier and method, and belongs to the technical field of immune cells. In the application, a heterocyclic small molecule, pimovanel phosphate, is used as a cGAS-STING pathway agonist, and is covalently coupled to a biodegradable carrier together with a cytokine. The innate immune activation characteristics of the cGAS-STING pathway and the proliferation regulation characteristics of the cytokine are used to form synergy, to simulate the immune activation mode in a physiological state, to activate the cGAS-STING / IRF3 / NF-kappa B immune pathway and the SIRT7-PGC-1alpha metabolic pathway, to promote glycolysis and mitochondrial biosynthesis, and finally to realize efficient expansion, enhanced efficacy and persistent improvement of NK cells.
