    摘要: Cancer immunotherapies effective for treating tumors are disclosed. A cytosolic receptor that detects viral ribonucleic acid (RNA), retinoic-acid-inducible protein 1 (RIG-I), is activated by a synthetic double-stranded oligonucleotide pUUC Auk. In one implementation, RIG-I is activated by a single-stranded oligonucleotide agonist formulated with a squalene emulsion (SE) adjuvant. Activation of RIG-I with pUUC Auk results in slower tumor growth. Formulation with a SE adjuvant increases the ability of RIG-I agonists to slow tumor growth. The novel agonist and formulations provided herein are effective for slowing the growth of new tumors and reducing further growth of established tumors. RIG-I agonist/adjuvant formulations may be administered to a subject by any of multiple routes including intratumoral injection.
