Ebolavirus Chimerization for the Development of a Mouse Model for Screening of Bundibugyo-Specific Antibodies.

Summary of "Ebolavirus Chimerization for the Development of a Mouse Model for Screening of Bundibugyo-Specific Antibodies."

Screening of monoclonal antibodies against ebolaviruses requires small-animal models. Wild-type mice require adaptation of ebolaviruses, whereas immunodeficient mice are still resistant to nonadapted Bundibugyo ebolavirus. Swapping of Ebola virus glycoprotein with that from Bundibugyo virus resulted in a replication-competent chimeric virus, which caused 100% lethal infection in STAT1 knockout mice. Monoclonal antibody BDBV223 isolated from a human survivor of Bundibugyo virus infection protected mice from challenge with the chimeric virus. These data demonstrate the suitability of the approach for in vivo screening of antibodies and suggest the greater contribution of internal Ebola proteins in pathogenesis compared to Bundibugyo virus proteins.

Medical and Biotech [MESH] Definitions

One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

A mouse substrain that is genetically predisposed to the development of systemic lupus erythematosus-like syndrome, which has been found to be clinically similar to the human disease. It has been determined that this mouse strain carries a mutation in the fas gene. Also, the MRL/lpr is a useful model to study behavioral and cognitive deficits found in autoimmune diseases and the efficacy of immunosuppressive agents.

An inbred strain of mouse. Specific substrains are used in a variety of areas of BIOMEDICAL RESEARCH such as DBA/1J, which is used as a model for RHEUMATOID ARTHRITIS.

Testing or screening required by federal, state, or local law or other agencies for the diagnosis of specified conditions. It is usually limited to specific populations such as categories of health care providers, members of the military, and prisoners or to specific situations such as premarital examinations or donor screening.

A genus in the family FILOVIRIDAE consisting of several distinct species of Ebolavirus, each containing separate strains. These viruses cause outbreaks of a contagious, hemorrhagic disease (HEMORRHAGIC FEVER, EBOLA) in humans, usually with high mortality.
