There is a critical need to develop vaccine adjuvants that induce robust immune responses able to protect against intracellular pathogens, including viruses. Previously, we described defective viral genome-derived oligonucleotides (DDOs) as novel adjuvants that strongly induce type 1 immune responses, including protective Th1 CD4+ T-cells and effector CD8+ T-cells in mice. Here, we unravel the early innate response required for this type 1 immunity induction.

However, there is a shortage of adjuvants that elicit robust type-1 immunity required for the control of intracellular pathogens, including viruses. RNA derived from Sendai virus defective viral genomes (DVGs) stimulates RIG-I-like receptor signaling leading to type-1 immunity during infection.
