recombinant proteins were evaluated as smallpox and monkeypox vaccines because of their perceived safety compared with live vaccinia virus. Previously, we showed that three or more injections of Ribi adjuvant-type with a triple combination of the outer membrane of intracellular proteins (L1 proteins) and extracellular (A33 and B5 protein) form of vaccinia virus protected mice against lethal intranasal challenge with vaccinia virus. Here, we compare some adjuvants and Hapten Conjugates Proteins found that QS-21, and to a lesser extent alum + oligodeoxynucleotides CpG accelerated and improved neutralizing antibody responses against a mixture of L1 and A33 protein, provided the highest ratio of IgG2a response of isotype IgG1, and mice are protected against disease and death after only two immunizations three weeks. In addition, the monkeys were immunized with recombinant vaccinia virus proteins and QS-21 developed neutralizing antibodies against monkeypox virus a...
Recombinant anti-vascular endothelial growth factor fusion protein efficiently suppresses choridal neovasularization in monkeys.
OBJECTIVE KH902 is a fusion protein that combines the ligand binding elements derived from the extracellular domain of vascular endothelial growth factor (VEGF) receptors 1 and 2 and the Fc portion of IgG1. This study was designed t o test the Cat Recombinant Proteins inhibitory effect of KH902 in a monkey model of choroidal neovascularization (CNV). METHOD Affinity binding to VEGF was measured using ELISA kits of human VEGF, and the effect of the biological activity of KH902 tested by in vitro inhibition experiments on human umbilical vein endothelial cell proliferation induced by VEGF. The experimental CNV induced by laser injury perimacular cause in the eyes of rhesus monkeys and confirmed by fluorescence fundus angiography (FFA), optical coherence tomography (OCT) and multifocal Electroretinograms (mf-ERG) 20 days after suffering from injury Laser. KH902 delivered to the animal via intravitreal injection at various doses. The monkeys were observed four weeks after injec...
