Input: Consider Input: Paragraph: Understanding the mechanisms that help promote protective immune responses to pathogens is a major challenge in biomedical research and an important goal for the design of innovative therapeutic or vaccination strategies. While natural killer (NK) cells can directly contribute to the control of viral replication, whether, and how, they may help orchestrate global antiviral defense is largely unknown. To address this question, we took advantage of the welldefined molecular interactions involved in the recognition of mouse cytomegalovirus (MCMV) by NK cells. By using congenic or mutant mice and wild-type versus genetically engineered viruses, we examined the consequences on antiviral CD8 T cell responses of specific defects in the ability of the NK cells to control MCMV. This system allowed us to demonstrate, to our knowledge for the first time, that NK cells accelerate CD8 T cell responses against a viral infection in vivo. Moreover, we identify the underlying mechanism as the ability of NK cells to limit IFN-a/b production to levels not immunosuppressive to the host. This is achieved through the early control of cytomegalovirus, which dramatically reduces the activation of plasmacytoid dendritic cells (pDCs) for cytokine production, preserves the conventional dendritic cell (cDC) compartment, and accelerates antiviral CD8 T cell responses. Conversely, exogenous IFN-a administration in resistant animals ablates cDCs and delays CD8 T cell activation in the face of NK cell control of viral replication. Collectively, our data demonstrate that the ability of NK cells to respond very early to cytomegalovirus infection critically contributes to balance the intensity of other innate immune responses, which dampens early immunopathology and promotes optimal initiation of antiviral CD8 T cell responses. Thus, the extent to which NK cell responses benefit the host goes beyond their direct antiviral effects and extends to the prevention of innate cytokine shock and to the promotion of adaptive immunity.

Input: Consider Input: Paragraph: Inspired by bioactive biaryl-containing natural products found in plants and the marine 19 environment, a series of synthetic compounds belonging to the azaBINOL chiral ligand family 20 was evaluated for antiviral activity against HIV-1. Testing of 39 unique azaBINOLs in a single-21 round infectivity assay resulted in the identification of three promising antiviral compounds, 22 including 7-isopropoxy-8-(naphth-1-yl)quinoline (azaBINOL B#24), which exhibited low-23 micromolar activity. The active compounds and several close structural analogues were further 24 tested against three different HIV-1 envelope pseudotyped viruses as well as in a full-virus 25 replication system (EASY-HIT). Mode-of-action studies using a time-of-addition assay indicated 26 that azaBINOL B#24 acts after viral entry but before viral assembly and budding. HIV-1 reverse 27 transcriptase (RT) assays that individually test for polymerase and RNase H activity were used to 28 demonstrate that B#24 inhibits RNase H activity, most likely allosterically. Further binding 29 analysis using bio-layer interferometry (BLI) showed that B#24 interacts with HIV-1 RT in a 30 highly specific manner. These results indicate that azaBINOL B#24 is a potentially viable, novel 31

Input: Consider Input: Paragraph: The collapse of iconic, keystone populations of sockeye (Oncorhynchus nerka) and Chinook (Oncorhynchus tshawytscha) salmon in the Northeast Pacific is of great concern. It is thought that infectious disease may contribute to declines, but little is known about viruses endemic to Pacific salmon. Metatranscriptomic sequencing and surveillance of dead and moribund cultured Chinook salmon revealed a novel arenavirus, reovirus and nidovirus. Sequencing revealed two different arenavirus variants which each infect wild Chinook and sockeye salmon. In situ hybridisation localised arenavirus mostly to blood cells. Population surveys of >6000 wild juvenile Chinook and sockeye salmon showed divergent distributions of viruses, implying different epidemiological processes. The discovery in dead and dying farmed salmon of previously unrecognised viruses that are also widely distributed in wild salmon, emphasizes the potential role that viral disease may play in the population dynamics of wild fish stocks, and the threat that these viruses may pose to aquaculture.
