A single N66S mutation in the PB1-F2 protein of influenza A virus increases virulence by inhibiting the early interferon response in vivo

ABSTRACT: This study used virological, histological, and global gene expression from an experimental murine model of influenza infection to study the contribution of a specific mutation in the PB1-F2 protein (PB1-F2 N66S) of influenza A to viral pathogenesis. 6-8 week old, wild-type, female, C57Bl/6 mice were inoculated individually with 30 μl (10^4 PFU) of virus (recombinant influenza A/WSN/33 carrying the PB1 gene segment from A/Hong Kong/156/97 (H5N1) or a PB1 mutant recombinant virus resulting in an amino acid change at position 66 in the PB1-F2 protein [N66S]) in phosphate-buffered saline (PBS) containing penicillin-streptomycin and bovine serum albumin (PBS-BA-PS). A total of 10^4 PFU of virus was given in all inoculations. Control mice were given PBS-BA-PS. Lung samples were taken for microarray analysis at 12h, 1d, 3d, and 5d post-infection (n=3 animals per group at each time point for virus infected animals; n=2 animals per time point for mock-infected animals).

Project description:This study used virological, histological, and global gene expression data to compare the virulence of two 2009 pH1N1 isolates from human (A/California/04/2009) and swine (A/swine/Alberta/25/2009) to that of a 1918-like classical swine influenza virus (A/swine/Iowa/1930) in a pig model of infection. The overall goal of this study was to characterize the clinical, histological, virological and global gene expression responses to three distinct influenza A isolates in an experimental pig model of influenza infection. We compared the pathogenesis of two pH1N1 viruses, one derived from a human patient (A/CA/04/09 [CA09]) and the other from swine (A/swine/Alberta/25/2009 [Alb09]), with that of the 1918-like classical swine influenza virus (A/swine/Iowa/1930 [IA30]) in the pig model. Both pH1N1 isolates induced clinical symptoms such as coughing, sneezing, decreased activity, fever, and labored breathing in challenged pigs, but IA30 virus did not cause any clinical symptoms except fever. Although both the pH1N1 viruses and the IA30 virus caused lung lesions, the pH1N1 viruses were shed from the nasal cavities of challenged pigs whereas the IA30 virus was not. Microarray was used to assess global gene expression in the lungs at 3 and 5 days post-infection. Crossbred pigs fwere obtained from a healthy herd free of SIV and porcine reproductive and respiratory syndrome virus. These studies included two experiments: the classical H1N1 SIV (IA30) study was completed at Kansas State University's biosafety level 2 (BSL-2) facility in compliance with the Institutional Animal Care and Use Committee at Kansas State University, and the pH1N1 virus study was completed at the Central States Research Center (CSRC), Inc., BSL-3 facility (Oakland, NE), in compliance with the Institutional Animal Care and Use Committee at CSRC. In each experiment, 10 pigs were inoculated with noninfectious cell culture supernatant as controls. For the classical H1N1 SIV experiment, 10 4-week-old crossbred pigs were inoculated intratracheally with 10^6 50% tissue culture infective doses (TCID50)/pig of egg-derived IA30 virus. For the pH1N1 virus experiment, 10 4-week-old crossbred pigs were inoculated intratracheally with 10^6 TCID50/pig of either egg-derived CA/09 or Alb/09 virus. Five animals per group were euthanized at 3 and 5 days postinfection (dpi), respectively.

Project description:The overall goal of the study was to use in vivo data combined with functional genomics to define gene expression signatures representative of a spectrum of HSV CNS infections. Innate immune deficiencies result in a spectrum of severe clinical outcomes following infection. In particular, there is a strong association between loss of the signal transducer and activator of transcription (Stat) pathway, breach of the blood-brain barrier (BBB), and virus-induced neuropathology. The gene signatures that characterize resistance, disease, and mortality in the virus-infected nervous system have not been defined. Herpes simplex virus type 1 (HSV-1) is commonly associated with encephalitis in humans, and humans and mice lacking Stat1 display increased susceptibility to HSV central nervous system (CNS) infections. In this study, two HSV-1 strains were used, KOS (wild type [WT]), and Δvhs, an avirulent recombinant lacking the virion host shutoff (vhs) function. In addition, two mouse strains were used: strain 129 (control) and a Stat1-deficient (Stat1(-/-)) strain. Using combinations of these virus and mouse strains, we established a model of infection resulting in three different outcomes: viral clearance without neurological disease (Δvhs infection of control mice), neurological disease followed by viral clearance (Δvhs infection of Stat1(-/-) mice and WT infection of control mice), or neurological disease followed by death (WT infection of Stat1(-/-) mice). Through the use of functional genomics on the infected brain stem and liver, we determined gene signatures that were representative of the three infection outcomes. Gender matched, 6- to 8- week old immunocompetent, control 129S6 and 129S6 Stat1 knockout mice were infected corneally with 2x10^6 PFU of either wild type HSV-1, a vhs-null HSV virus, or mock-infected. Brain stems and liver of individual mice were isolated at days 1, 3, 5 and 7 post-inoculation for microarray analysis. For microarray analysis, samples were collected from n=2 animals (1 male, 1 female) per mouse strain and virus strain for each time point. Equal masses of tissue were pooled from two mock-infected mice per time point and run on microarray.
