Abstract
Poly(ADP ribose) polymerase inhibitors (PARPi) have efficacy in triple negative breast (TNBC) and ovarian cancers (OCs) harboring BRCA mutations, generating homologous recombination deficiencies (HRDs). DNA methyltransferase inhibitors (DNMTi) increase PARP trapping and reprogram the DNA damage response to generate HRD, sensitizing BRCA-proficient cancers to PARPi. We now define the mechanisms through which HRD is induced in BRCA-proficient TNBC and OC. DNMTi in combination with PARPi up-regulate broad innate immune and inflammasome-like signaling events, driven in part by stimulator of interferon genes (STING), to unexpectedly directly generate HRD. This inverse relationship between inflammation and DNA repair is critical, not only for the induced phenotype, but also appears as a widespread occurrence in The Cancer Genome Atlas datasets and cancer subtypes. These discerned interactions between inflammation signaling and DNA repair mechanisms now elucidate how epigenetic therapy enhances PARPi efficacy in the setting of BRCA-proficient cancer. This paradigm will be tested in a phase I/II TNBC clinical trial.

Abstract
The respiratory epithelium consists of lung sentinel cells, which are the first to contact inhaled inflammatory insults, including air pollutants, smoke, and microorganisms. To avoid damaging exuberant or chronic inflammation, the inflammatory process must be tightly controlled and terminated once the insult is mitigated. Inflammation resolution is now known to be an active process involving a new genus of lipid mediators, called "specialized proresolving lipid mediators," that includes resolvin D1 (RvD1). We and others have reported that RvD1 counteracts proinflammatory signaling and promotes resolution. A knowledge gap is that the specific cellular targets and mechanisms of action for RvD1 remain largely unknown. In this article, we identified the mechanism whereby RvD1 disrupts inflammatory mediator production induced by the viral mimic polyinosinic-polycytidylic acid [poly(I:C)] in primary human lung epithelial cells. RvD1 strongly suppressed the viral mimic poly(I:C)-induced IL-6 and IL-8 production and proinflammatory signaling involving MAPKs and NF-κB. Most importantly, we found that RvD1 inhibited the phosphorylation of TAK1 (TGF-β-activated kinase 1), a key upstream regulatory kinase common to both the MAPK and NF-κB pathways, by inhibiting the formation of a poly(I:C)-induced signaling complex composed of TAK1, TAB1 (TAK1 binding protein), and TRAF6 (TNF receptor-associated factor 6). We confirmed that ALX/FPR2 and GPR32, two RvD1 receptors, were expressed on human small airway epithelial cells. Furthermore, blocking these receptors abrogated the inhibitory action of RvD1. In this article, we present the idea that RvD1 has the potential to be used as an anti-inflammatory and proresolving agent, possibly in the context of exuberant host responses to damaging respirable agents such as viruses.

Abstract
We and others demonstrated that the contact between NS5A and the host factor CypA is critical for HCV replication. CypI, by disrupting NS5A-CypA complexes, block HCV replication both in vitro and in patients. Since NS5A also binds to PKR, a central component of the IFN response, we investigated the possibility of a relationship between CypA, NS5A and PKR in the IFN response to HCV. HCV-infected cells treated with CypI, DAAs or IFN were analyzed for the expression and activation of various components of the innate response. We found that CypI (cyclosporine A, alisporivir, NIM811 and sanglifehrins), drastically prevented the activation/phosphorylation, but not the expression of IFN-induced PKR in HCV-infected cells. CypI had no effect on the expression or phosphorylation of other components of the innate response such as eiF2, NF-kB, IRF3, IRF9, STAT1 and STAT2, suggesting a specific effect on PKR. No significant activation of IFN-induced PKR was observed in the absence of HCV. Importantly, we found that several classes of DAAs such as NS3/4A protease, NS5B polymerase and NS5A inhibitors also prevented PKR activation. Furthermore, we found that PKR activation by the dsRNA mimic poly I:C cannot be prevented by CypI or DAAs. Our findings suggest that CypI do not have a unique effect on PKR activation, but rather the suppression of HCV replication by any anti-HCV inhibitor, abrogates PKR activation induced by IFN. Moreover, they suggest that the accumulation of dsRNA intermediates allows HCV to exploit the activation of PKR to counteract the IFN response.

Abstract
Aerosols of double-stranded complexes of polyinosinic and polycytidylic acids (poly I:C) were useful in protecting mice infected with aerosols of influenza (A(2)/Taiwan/64) and parainfluenza type 1 (Sendai) viruses. Administration of poly I:C as an aerosol offers an advantage, particularly in therapy, by eliminating the risk of pulmonary dissemination of viral infections due to intranasally instilled fluids. Treatment of mice with aerosols of poly I:C reduced the infection rate with influenza virus but did not inhibit virus multiplication in the lungs of most of those animals where infection became established. Sendai virus infection rates were undiminished in mice treated with poly I:C, but lung-virus titers were significantly suppressed as compared with those of untreated animals. The maximum poly I:C doses (40 mug) administered by aerosol produced no evidence of toxicity in the mice.

Abstract
Due to the inherent lack of immunogenicity of peptides, it is generally recognized that the strong inflammatory signals that are required to elicit specific responses against peptide-based therapeutic tumor vaccines may not be provided by the standard/conventional vaccine adjuvants. In this study, we have demonstrated dsRNA in the form of synthetic pI:C as a potent adjuvant to enhance the specific anti-tumor immune responses against a peptide-based vaccine. When complexed with an MHC I-restricted minimal peptide epitope derived from the HPV 16 E7 protein, the resulting pI:C/E7(49-57) molecular complex induced strong E7(49-57)-specific CTL responses that caused significant regressions of model human cervical cancer tumors pre-established in mice. In addition, although the proportion of DCs in tumor-bearing mice was significantly decreased when compared to that in naïve mice, immunization with pI:C/E7(49-57 )restored the proportion of DCs in tumor-bearing mice. Double-stranded RNA may hold a great potential as an adjuvant to induce cellular immune responses for tumor immunotherapy.

Abstract
It was found that intravenous injection of the synthetic double-stranded ribonucleic acid, polyinosinic-polycytidylic acid [poly(I:C)], which is a well-studied interferon (IFN)-inducing agent, can result in extensive hemorrhagic necrosis of the center of an established murine sarcoma and in subsequent complete regression of the surviving rim of the tumor. The poly(I:C)-induced intratumor hemorrhagic reaction was associated with production of appreciable quantities of tumor necrosis factor (TNF) by the host. Neutralization of TNF by treatment with anti-rTNF immunoglobulin G (IgG) caused substantial inhibition of hemorrhagic necrosis and prevented tumor regression from proceeding. Tumor regression was prevented in all mice by depleting them of CD8+ T cells 1 day before poly(I:C) was given. Taken as a whole, the results indicate that the antitumor action of poly(I:C), like that of endotoxin, is based on its capacity to induce the host to make enough TNF to cause a hemorrhagic reaction extensive enough to reduce the tumor burden to a size capable of being dealt with by an underlying host antitumor immune response.

Abstract
Susceptibility of eight strains of influenza A and B viruses to interferon and to poly(I) . poly(C) were determined by the plaque reduction method. All strains tested were slightly less susceptible than vesicular stomatitis virus (VSV) in an established line of canine kidney (MDCK) cells. The 50% plaque depression doses (PD50) of poly(I) . poly(C) for influenza A and B viruses were as high as 3.0- to 4.5-fold and 6- to 18-fold that for VSV, respectively. The amounts of interferon required to inhibit plaque formation of influenza A and B viruses by 50% were 3.0-6.2 and 7.3-15.2 units/ml, respectively. The ratio of PD50 of poly(I) . poly(C) for each strain of influenza viruses tested to that for VSV in chick embryo cells was almost the same as in MDCK cells. Furthermore, in chick embryo cells, the strains of influenza virus tested were demonstrated to be much more susceptible to poly(I) . poly(C) than both Newcastle disease virus and vaccinia virus. It is suggested that influenza viruses may be relatively susceptible to interferon and to poly(I) . poly(C).

Abstract
Interferon inducers are generally most effective as antiviral agents when used prophylactically. One possible explanation for this is that animals develop a state of hyporeactivity during the course of a virus infection. Such a progressive loss of capacity to produce interferon was observed with a representative group of interferon-inducing agents (polyinosinic-cytidylic acid, Tilorone hydrochloride, New-castle disease virus, or a strain of encephalomyocarditis virus) during the course of a model picornavirus infection in mice.

Abstract
Mouse resistance to foot-and-mouth disease virus (FMDV) was induced by intraperitoneal injections of pyran copolymer. A biphasic pattern of protection occurred with greatest resistance 4 and 48 hr after injection of this polyanion. Viremia was not detectable in pretreated mice challenge-exposed with FMDV. Incubation of virus with pyran did not alter viral infectivity in mice or tissue culture. Serum interferon was demonstrated 1 and 2 days after pyran administration.

Abstract
The interferon inducer double-stranded polyinosinic acid and polycytidylic acid (poly I:C) was studied in hamsters experimentally infected with parainfluenza 3 virus. Upper intranasal, deep intranasal, or intraperitoneal treatment of hamsters with poly I:C (100 mug/100- to 120-g animal) 24 hr before an upper respiratory infection significantly reduced the virus yields taken 28 hr after infection. Deep intranasal and intraperitoneal treatment with poly I:C greatly decreased the virus titers in the lungs, as measured 48 hr after a deep lung infection with parainfluenza 3 virus; however, the upper respiratory poly I:C treatment was ineffective.

Abstract
Intravenous injection of polyinosinic acid/polycytidylic acid [(poly rI).(poly rC)] offered significant protection against intranasal challenge of young mice with vesicular stomatitis virus (VSV). Optimal protection was obtained when a single dose was administered 2 hr before virus challenge, but repeated doses were effective when started as late as 3 days after virus challenge. The therapeutic ratio or ratio of maximum tolerated dose to minimum effective dose for a single intravenous injection of (poly rI).(poly rC) 2 hr before virus inoculation was >/=8 mg/kg:0.004 mg/kg or >/=200.Dose-response curves for interferon production and antiviral protection by (poly rI).(poly rC) were closely parallel. Equivalent doses of poly rI or poly rC alone did not exert any interferon-inducing capacity or protective effect on intranasal VSV challenge. Several factors, which are known to potentiate or antagonize interferon production, increased or decreased the interferon-inducing capacity and antiviral protection of either (poly rI).(poly rC) or maleic acid/divinyl ether copolymer (MA/DVE) in parallel. Interferon production and antiviral protection by MA/DVE were enhanced by arginine but abolished by prior treatment with MA/DVE; DEAE-dextran (intraperitoneally), kinetin riboside and isopentenyladenosine, and prior injection of endotoxin reduced both interferon production and antiviral protection by (poly rI).(poly rC). Treatment with exogenous interferon in amounts which closely mimicked the levels of circulating interferon produced endogenously by an effective dose of (poly rI).(poly rC) gave protection against intranasal VSV which was identical with that dose of (poly rI).(poly rC). This strongly suggests that interferon production accounts for the whole protective effect of (poly rI).(poly rC) in the intranasal VSV assay.
