Recombinant Nipah F Proteins and Their Use

Nipah virus is an emerging pathogenic paramyxovirus responsible for sporadic and isolated outbreaks of severe respiratory and neurologic disease in Southern Asia. As a zoonotic virus, disease can manifest in both animals and human with indigenous fruit bats acting as natural reservoirs of the virus. The effects of viral infection vary from acute respiratory distress to fatal encephalitis. There are currently no approved therapeutics or vaccines against the virus, and growing concerns that this highly pathogenic infection has the potential to cause larger epidemics capable of inflicting significant mortality burden.Like the RSV fusion (F) glycoprotein, the Nipah fusion glycoprotein is a target of neutralizing antibodies that mediate protection against infection. Previous studies of prefusion-stabilized F glycoproteins from pneumoviruses and other paramyxoviruses (e.g. RSV and PIVs) have shown they elicit higher titers of neutralizing antibodies in both animals and humans than post-fusion F proteins.Researchers at the Vaccine Research Center (VRC) of the National Institute of Allergy and Infectious Diseases (NIAID) designed disulfide, cavity-filling and other mutations that stabilize the Nipah F glycoprotein in the prefusion conformation and bind prefusion-specific antibodies. These mutations also increase protein expression yields up to 50-fold making the recombinant proteins easy to manufacture and amenable to the use of genetic immunization using nucleic acid or vector-based...

The polymeric materials present in the biofilm architecture hinder the entry of antimicrobial compounds through the surface of bacterial cells which are embedded as well as enclosed beneath the biofilm matrix. Recent and past studies explored the alternative approaches to inhibit ...

This study assessed the prevalence, risk factors, and co-infectivity of CTBP such as piroplasms, rickettsiae, Coxiella burnetii, hepatozoa, hemotropic mycoplasmas, and Borrelia spp., using PCR and phylogenetic analyses. Of the 510 dogs tested, three CTBP, including Anaplasma phagocytophilum 16S rRNA (13; 2.6%), Hepatozoon canis 18S rRNA (2; 0.4%), and Mycoplasma haemocanis 16S rRNA (1; 0.2%) were detected. PCR adapted to amplify A. phagocytophilum msp2 and groEL genes generated amplicons thereof in two out of 13 positive dogs. One shelter dog was co-infected with A. phagocytophilum and M. haemocanis. However, Ehrlichia spp...

HofmeesterAbstractCattle grazing has been suggested to reduce the risk for Lyme borreliosis by decreasing the density of questing Ixodes ricinus infected with Borrelia burgdorferi sensu lato. We tested the hypotheses that cattle grazing used in woodland management decreases the density of questing I. ricinus, and that it decreases the nympal infection prevalence of B. burgdorferi sensu lato. We further expected the nympal infection prevalence of tick-borne pathogens that ...

Authors: Babaer D, Zheng M, Ivy MT, Zent R, Tiriveedhi V Abstract Previous phase I DNA-vaccine based clinical trials using Mammaglobin-A (Mam-A), a human breast tumor associated antigen (TAA), demonstrated that this agent was safe and efficient at treating patients with stage IV breast cancer. The long-term success of cancer vaccines is limited by the diminished expression of human leukocyte antigen (HLA) class I molecules in the tumor microenvironment. The current study assessed the impact of various selenocompounds on the expression of HLA class I molecules in THP-1 cells, an apparent proficient antigen that pres...
