We generated models of IFN signaling defects in B16 murine melanoma observed in patients with acquired resistance to ICB. Tumors lacking <i>Jak1</i> or <i>Jak2</i> did not respond to ICB, whereas ACT was effective against <i>Jak2</i> <sup>KO</sup> tumors, but not <i>Jak1</i> <sup>KO</sup> tumors, where both type I and II tumor IFN signaling were defective. This was a direct result of low baseline class I major histocompatibility complex (MHC I) expression in B16 and the dependency of MHC I expression on either type I or type II IFN signaling. We used genetic and pharmacologic approaches to uncouple this dependency and restore MHC I expression. Through independent mechanisms, overexpression of NLRC5 (nucleotide-binding oligomerization domain-like receptor family caspase recruitment domain containing 5) and intratumoral delivery of BO-112, a potent nanoplexed version of polyinosinic:polycytidylic acid (poly I:C), each restored the efficacy of ACT against B16-<i>Jak1</i> <sup>KO</sup> tumors. BO-112 activated double-stranded RNA (dsRNA) sensing (via protein kinase R and Toll-like receptor 3) and induced MHC I expression via nuclear factor κB, independent of both IFN signaling and NLRC5. In summary, we demonstrated that in the absence of tumor IFN signaling, MHC I expression is essential and sufficient for the efficacy of ACT. For tumors lacking MHC I expression due to deficient IFN signaling, activation of dsRNA sensors by BO-112 affords an alternative approach to restore the efficacy of ACT."],"journal":["Science translational medicine"],"pubmed_title":["Uncoupling interferon signaling and antigen presentation to overcome immunotherapy resistance due to JAK1 loss in melanoma."],"pmcid":["PMC8053376"],"funding_grant_id":["N/A","KL2 TR001882","P30 AI028697","P30 CA016042","R35 CA197633","CA168585","P01 CA168585","T32 CA009120","T32-CA009120","TR001882","CA197633","P01 CA244118"],"pubmed_authors":["Ribas A","Speiser DE","Tariveranmoshabad M","Parisi G","Quintero M","Kremer S","Zaretsky JM","Kalbasi A","Campbell KM","Vega-Crespo A","Funes JM","Lopez-Casas PP","Shin D","Champekar A","Nguyen C","Torrejon D","Damoiseaux RD","Hakimi K"],"additional_accession":[]},"is_claimable":false,"name":"Uncoupling interferon signaling and antigen presentation to overcome immunotherapy resistance due to JAK1 loss in melanoma.","description":"Defects in tumor-intrinsic interferon (IFN) signaling result in failure of immune checkpoint blockade (ICB) against cancer, but these tumors may still maintain sensitivity to T cell-based adoptive cell therapy (ACT).
