The interferon (IFN) family consisting of alpha IFN (IFN-alpha), IFN-beta, IFN-omega, IFN-delta, IFN-kappa, and IFN-tau is a large group of cytokines involved in the innate immune response against various microorganisms. Genes for IFN have been cloned from a variety of mammalian and avian species; however, IFN genes from lower-order vertebrates have not(More)
Recently, the zebrafish, Danio rerio, has been recognized as a useful model for infectious disease and immunity. The Toll-like receptor (TLR) family is an evolutionarily conserved component of the innate immune system that responds to specific pathogen-associated molecular patterns (PAMPs) during an infection. This study reports the identification and(More)
The zebrafish (Danio rerio) is a widely used model for developmental biology, neurobiology, toxicology, and genetic disease. Recently, the zebrafish has been recognized as a valuable model for infectious disease and immunity. In this study the pathogenesis and inflammatory cytokine response of zebrafish to experimental Edwardsiella tarda infection was(More)
BACKGROUND The main technological impediment to widespread utilization of lignocellulose for the production of fuels and chemicals is the lack of low-cost technologies to overcome its recalcitrance. Organisms that hydrolyze lignocellulose and produce a valuable product such as ethanol at a high rate and titer could significantly reduce the costs of biomass(More)
The zebrafish, Danio rerio, has become recognized as a valuable model for the study of development, genetics, and toxicology. Recently, the zebrafish has been recognized as a useful model for infectious disease and immunity. In this study, the pathogenesis and antiviral immune response of zebrafish to experimental snakehead rhabdovirus (SHRV) infection was(More)
Type I interferons (IFNs) represent a crucial component of the innate immune response to viruses. An important downstream effector of IFN is the Mx gene, which is activated solely through this pathway. Mx proteins are characterized by a tripartite GTP-binding domain, dynamin family signature, and leucine zipper motif. Mx genes are transcribed upon(More)
The daily cycle of nitrogenase expression in the marine filamentous nonheterocystous cyanobacterium Trichodesmium spp. is controlled by a circadian rhythm. We evaluated the rhythm of two key photosynthesis genes, psbA of photosystem II and psaA of photosystem I, in Trichodesmium sp. IMS 101 using the 3 criteria for an endogenous rhythm. The transcript(More)
The methylotrophic yeast, Pichiapastoris, is an important organism used for the production of therapeutic proteins. However, the presence of fungal-like glycans, either N-linked or O-linked, can elicit an immune response or enable the expressed protein to bind to mannose receptors, thus reducing their efficacy. Previously we have reported the elimination of(More)
