Influenza A viruses with the presence of mutations in M2 still circulate and threaten to avian species and human in China. A novel M2 inhibitor pinanamine was previously identified as an antiviral agent by an in vitro assay. In this study, we monitored the activity of pinanamine against influenza A/FM1/47 (H1N1) virus infection in cell culture and mice. Pinanamine showed more potent antiviral effect than ribavirin, and was as effective as oseltamivir carboxylate and amantadine in Madin-Darby canine kidney (MDCK) cells...

Infections with lethal influenza viruses lead to acute lung injury (ALI) or acute respiratory distress syndrome (ARDS), which may be related to the activation of the host's immune system. Here, in our study, male C57BL/6 mice were infected with 10 LD50 of the H5N1 influenza virus and treated with geldanamycin or oseltamivir 2 h after infection. Lung injury was assessed by histopathology on days 4 and 7. The viral load was quantified by measuring the NP gene expression level on days 2, 4, and 7. Levels of cytokines and chemokines in bronchoalveolar lavage fluids and inflammatory cells were analyzed at different time points...

To assess the extent of susceptibility to the four most commonly used neuraminidase inhibitors (NAIs) in the viruses epidemic in the 2015-2016 influenza season in Japan, we measured the 50% inhibitory concentration (IC50) of NAIs for influenza virus isolates and compared them with the results from the 2010-11 to 2014-15 influenza seasons. Viral isolation was done with specimens obtained prior to treatment, and the type and subtype of influenza was determined by RT-PCR using type- and subtype-specific primers...

Central Nervous System inflammation has been implicated in neurodegenerative disorders including Parkinson's disease (Ransohoff, Science 353: 777-783, 2016; Kannarkat et al. J. Parkinsons Dis. 3: 493-514, 2013). Here, we examined if the H1N1 influenza virus (Studahl et al. Drugs 73: 131-158, 2013) could synergize with the parkinsonian toxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (Jackson-Lewis et al. in Mark LeDoux (ed) Movement Disorders: Genetics and Models: 287-306, Elsevier, 2015) to induce a greater microglial activation and loss of substantia nigra pars compacta dopaminergic neurons than either insult alone...

Context • Outbreaks of the influenza A virus (IAV) are increasingly recognized as a global public health issue, affecting a large proportion of the world's population. A number of studies have provided epidemiologic evidence that dampness and mold are consistently associated with multiple allergic and respiratory effects, but they focused on dampness-related pathogenic microorganisms leading to allergy rather than the dampness itself. Objective • The current study intended to examine the effects of a damp environment on the promotion of the IAV and determine the adverse effects on its prognosis through upregulation of the toll-like receptor 7 (TLR7)-signaling pathway in the lung...

Neuraminidase, which plays a critical role in the influenza virus life cycle, is a target for new therapeutic agents. The study of structure-activity relationships revealed that the C-5 position amino group of oseltamivir was pointed to 150-cavity of the neuraminidase in group-1. This cavity is important for selectivity of inhibitors against N1 versus N2 NA. A serial of influenza neuraminidase inhibitors with the oseltavimir scaffold containing lipophilic side chains at the C-5 position have been synthesized and evaluated for their influenza neuraminidase inhibitory activity and selectivity...

Influenza virus infection often causes severe disease and acute respiratory distress syndrome. It is a common belief that overwhelming immune response contributes to the severe illness. Physicians and researchers have put forth immune modulation as salvage therapy for better recovery. However, empiric corticosteroid failed in both humans and animal models. Reported success with Rapamycin in humans prompted a comprehensive animal study and mechanistic dissection. Here we report the effect of Rapamycin alone or in combination with Oseltamivir for severe influenza in BALB/c mice...

Background: MEDI8852 is a novel MAb which neutralizes both group I and group II influenza A viruses (IAV) in vitro. We evaluated whether MEDI8852 was effective for prophylaxis and therapy against representative group I (H5N1) and group II (H7N9) pandemic IAV in mice and ferrets and could be used to block transmission of influenza H1N1pdm09 in ferrets, compared to an irrelevant control MAb R347 and oseltamivir. Results: MEDI8852 was effective for prophylaxis and treatment of H7N9 and H5N1 infection in mice, with a clear dose-dependent response and treatment with MEDI8852 24, 48 or 72 h post-infection (hpi) was superior to oseltamivir for H5N1...

Over the last decade, an increasing proportion of circulating human influenza A(H3N2) viruses exhibited haemagglutination activity that was sensitive to neuraminidase inhibitors. This change in haemagglutination as compared to older circulating A(H3N2) viruses prompted an investigation of the underlying molecular basis. Recent human influenza A(H3N2) viruses were found to agglutinate turkey erythrocytes in a manner that could be blocked with either oseltamivir or neuraminidase-specific antisera, indicating that agglutination was driven by neuraminidase, with a low or negligible contribution of haemagglutinin...
