Input: Consider Input: Interferon lambda 4 (IFN4) has been recently known and studied for its role in hepatitis C virus (HCV) infection, but its clinical potential is significantly hampered due to its poor expression in vitro. Our study reports the successful production of IFN4 from a mammalian cell line through a glycoengineering and structure-based approach. We introduced de novo N-glycosylation of IFN4, guided by structural analysis, and produced IFN4 variants in Expi293F that displayed improved expression and potency. To preserve the structure and functionality of IFN4, the model structure of the IFN4 signaling complex was analyzed and the N-glycosylation candidate sites were selected. The receptor binding activity of engineered IFN4 variants and their receptormediated signaling pathway were similar to the E. coli version of IFN4 (eIFN4), while the antiviral activity and induction levels of interferon-stimulated gene (ISG) were all more robust in our variants. Our engineered IFN4 variants may be further developed for clinical applications and utilized in basic research to decipher the immunological roles of IFN4. Previously, the transient expression of wild-type IFN4 in mammalian cells failed to produce significant amounts of recombinant

Output: Structure-based glycoengineering of interferon lambda 4 enhances its productivity and anti-viral potency

Input: Consider Input: The family Potyviridae encompasses~30% of plant viruses and is responsible for significant economic losses worldwide. Recently, a small overlapping coding sequence, termed pipo, was found to be conserved in the genomes of all potyvirids. PIPO is expressed as part of a frameshift protein, P3N-PIPO, which is essential for virus cell-to-cell movement. However, the frameshift expression mechanism has hitherto remained unknown. Here, we demonstrate that transcriptional slippage, specific to the viral RNA polymerase, results in a population of transcripts with an additional "A" inserted within a highly conserved GAAAAAA sequence, thus enabling expression of P3N-PIPO. The slippage efficiency is~2% in Turnip mosaic virus and slippage is inhibited by mutations in the GAAAAAA sequence. While utilization of transcriptional slippage is well known in negative-sense RNA viruses such as Ebola, mumps and measles, to our knowledge this is the first report of its widespread utilization for gene expression in positive-sense RNA viruses.

Output: Transcriptional slippage in the positive-sense RNA virus family Potyviridae

Input: Consider Input: Background: The intention of the following study was to describe the interrelationship between villagers, domestic animals and wildlife at the Community Forestry Concession of Uaxactun, Guatemala by means of participatory epidemiological methods. The main focus was generating information regarding different livestock diseases considered important by villagers and their relevance, as well as obtaining knowledge concerning hunting activities and cooking methods to gain a better understanding of the interrelationship of people and animals and the diseases of their animals. For poultry, an overall prevalence of 41 % of Newcastle disease was found by means of the ELISA test by antibody detection, chicken being the most affected species in the village. No samples were positive to avian influenza with the HI test. No virus was isolated by means of the tracheal or cloaca swabbing of ducks. For hunting: All species could be hunted by chance at any time of the year. There was a difference in species hunted between seasons, peccaries being more frequently hunted during the dry season and in contrast, deer and wild avian during the rainy season. For cooking: Villagers did not consume any raw meat. The cooking methods depended on the species. Stewing was the most favoured method for peccaries, wild birds, tepezcuintle and domestic poultry, whereas grilling was preferable for deer, roasting for armadillos and marinating for pork. According to the generated information, the most important domestic livestock species in the village are chickens and pigs, chickens being the most affected by diseases. No evident health problems on pigs were observed in this study. Hunting was shown as an activity enhanced by poverty and the lack of employment opportunities in the village and was mostly directed at larger species such as deer and peccaries. From the viewpoint of a transmission of zoonoses from animals to humans cooking methods mostly reflected a protective factor as no raw meat was eaten, stews and broths being the most common forms of cooking, involving an exposure of meat to high temperatures. Nonetheless, both agricultural and hunting activities represent a risk factor for the spread of diseases as hunters may act as mechanical vectors for different pathogens within domestic and wild animal populations.
Output: Participatory epidemiology at the neotropics: study of diseases of backyard livestock and description of hunting patterns in Uaxactun, Maya Reserve Biosphere, Guatemala
