Human cytomegalovirus (HCMV) is the leading cause of congenital viral infection, and developing a prophylactic vaccine is of high priority to public health. We recently reported a replication-defective human cytomegalovirus with restored pentameric complex glycoprotein H (gH)/gL/pUL128-131 for prevention of congenital HCMV infection. While the quantity of vaccine-induced antibody responses can ...
INTRODUCTION Population surveys for the presence of adenovirus complement-fixing (C.F.) and neutralizing antibodies suggest that certain serotypes, particularly types 1 and 2, are endemic. Huebner, Rowe, Ward, Parrott & Betts (1954) estimated that, of children in Washington in the age group 6-11 months, over 50 % had antibodies against one or more serotypes and 30 % had antibody against type 1 ...
Background: VP4 protein is as spikes on rotavirus outer capsid shell which is responsible for virus attachment to the host. VP4 induces production of neutralizing antibodies which could be used for serotyping of different isolates. Methods: Simian rotavirus SA11 gene 4 cDNA was cloned into a cloning plasmid pDONRTM by recombination reaction using clonase II enzyme mix. The resulting clone was c...
As part of an effort to engineer ricin antitoxins and immunotherapies, we previously produced and characterized a collection of phage-displayed, heavy chain-only antibodies (VHHs) from alpacas that had been immunized with ricin antigens. In our initial screens, we identified nine VHHs directed against ricin toxin's binding subunit (RTB), but only one, JIZ-B7, had toxin-neutralizing activity. Li...
Elicitation of antibodies with potent and broad neutralizing activity against HIV by immunization remains a challenge. Several monoclonal antibodies (mAbs) isolated from humans with HIV-1 infection exhibit such activity but vaccine immunogens based on structures containing their epitopes have not been successful for their elicitation. All known broadly neutralizing mAbs (bnmAbs) are immunoglobu...
Lymphocytic choriomeningitis virus (LCMV) is a murine arenavirus whose glycoprotein consists of a transmembrane subunit (GP-2) and a receptor-binding subunit (GP-1). LCMV-neutralizing antibodies (nAbs) are directed against a single site on GP-1 and occur 1 month after the infection of cytotoxic-T-lymphocyte (CTL) deficient mice. In wild-type mice, however, CTLs control early infection, and weak...
UNLABELLED HIV-1 envelope glycoprotein (Env) spikes are prime vaccine candidates, at least in principle, but suffer from instability, molecular heterogeneity and a low copy number on virions. We anticipated that chemical cross-linking of HIV-1 would allow purification and molecular characterization of trimeric Env spikes, as well as high copy number immunization. Broadly neutralizing antibodies...
We established an improved method for the generation of mouse monoclonal antibodies (MAbs) to gangliosides by immunizing mice with purified gangliosides. Using this method, we generated and characterized a large number of the MAbs specific for gangliosides. These MAbs enabled us to examine the distribution of ganglioside in the brain. Immunohistoand immunocyto-chemical studies suggested that th...
