Antibody responses of pigs to defined Erns fragments, after classical swine fever virus (CSFV) infection, were studied by using an enzyme-linked immunosorbent assay (ELISA). Selection of various E(rns) fragments was based on an immunodominant Erns region encompassing three overlapping antigenic regions, amino acids 65 to 145 (Erns(aa)65-145) (AR1), 84 to 160 (Erns(aa)84-160) (AR2), and 109 to 2...
Classical swine fever virus and bovine virus diarrhea virus are members of the genus pestivirus, which belongs to the family of the Flaviviridae. Recently, envelope glycoprotein Erns was identified as an RNase. RNases can express different biological actions. They have been shown to be neurotoxic, antihelminthic, and immunosuppressive. We studied the immunosuppressive properties of Erns in vitr...
Pestiviruses express a peculiar protein named Erns representing envelope glycoprotein and RNase, which is important for control of the innate immune response and persistent infection. The latter functions are connected with secretion of a certain amount of Erns from the infected cell. Retention/secretion of Erns is most likely controlled by its unusual membrane anchor, a long amphipathic helix ...
Communication and Cross‐Regulation between Chemically Fueled Sender and Receiver Reaction Networks**
Nature connects multiple fuel-driven chemical/enzymatic reaction networks (CRNs/ERNs) via cross-regulation to hierarchically control biofunctions for a tailored adaption in complex sensory landscapes. Herein, we introduce facile example of communication and among two DNA-based ERNs regulated by concatenated RNA transcription regulator. ERN1 (“sender”) is designed the promoter formation T7 polym...
Amphipathic α-helices of exchangeable apolipoproteins have shown to play crucial roles in the formation of infectious hepatitis C virus (HCV) particles through the interaction with viral particles. Among the Flaviviridae members, pestivirus and flavivirus possess a viral structural protein Erns or a non-structural protein 1 (NS1) as secretory glycoproteins, respectively, while Hepacivirus inclu...
results based on our results, mab against recombinant erns was produced and reacted successfully with recombinant and natural antigens. conclusions with regards to the role of erns in the identification of pi animals, it appears that erns recombinant antigen and the specific monoclonal antibodies produced against it may be suitable for developing bvdv laboratory diagnostic assays. objectives er...
BACKGROUND: Alcoholism is characterized by impaired decision-making (i.e., choosing intoxication in the face of mounting negative consequences). This impairment may involve a reduced brain response to the negative consequences of behavior, which supports an inclination to engage in risky behaviors. The feedback error-related negativity (F-ERN) is hypothesized to reflect the valence attached to ...
A call from the EU for the set-up of European Reference Networks (ERNs) is expected to be launched in the first quarter of 2016. ERNs are intended to improve the care for patients with low prevalent or rare diseases throughout the EU by, among other things, facilitating the pooling and exchange of experience and knowledge and the development of protocols and guidelines. In the past, for example...
Erns is a structural glycoprotein of pestiviruses found to be attached to the virion and tomembraneswithin infected cells via its COOH terminus, although it lacks a hydrophobic anchor sequence. The COOH-terminal sequence was hypothesized to fold into an amphipathic -helix. Alanine insertion scanning revealed that the ability of the Erns COOH terminus to bind membranes is considerably reduced by...
BACKGROUND Bovine viral diarrhea (BVD) is an economically important cattle disease with a worldwide distribution. Detection and elimination of animals persistently infected (PI) with bovine viral diarrhea virus (BVDV) is essential for the control of BVD and eradication of BVDV. There are usually no pathognomonic clinical signs of BVDV infection. Diagnostic investigations therefore rely on labor...
