Abstract:
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.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
