Conformation Dependent Anti-major Outer Membrane Protein (MOMP) Monoclonal Antibody BD5

A murine hybridoma expressing mAb BD3 was found to react with a conformationally dependent epitope on the chlamydial Major Outer Membrane Protein (MOMP), a primary target of neutralizing antibodies and vaccine development. The BD3 neutralized the in vitro infectivity of C. trachomatis serovars B, Ba, D, E, L2. It is useful for verifying the correct conformation of MOMP in vaccines against chlamydia trachomatis, Serovars B, BA, D, E, AND L2.

Enhanced Tissue Clearing Solution, Clearing-Enhanced 3D (Ce3D), Compatible with Advanced Fluorescence Microscopy Imaging

NIH immunologists have created a solution, Clearing-enhanced 3D (Ce3D), that can be used to make entire organs extremely transparent (top right panel). This allows the tissue to be imaged using advanced fluorescence microscopy techniques (bottom panel). Unlike current tissue clearing solutions, the Ce3D tissue clearing solution is robustly compatible with a variety of staining methods, and preserves tissue morphology and reporter fluorescence. Ce3D enabled microscopy provides unprecedented insight into the spatial organization of cells within intact organs.

Mononegavirales Vectors expressing Chimeric Antigens

Human respiratory syncytial virus (RSV) continues to be the leading viral cause of severe acute lower respiratory tract disease in infants and children worldwide. A licensed vaccine or antiviral drug suitable for routine use remains unavailable. This invention relates to the use of murine pneumonia virus (MPV), a virus to which humans normally are not exposed to and that is not cross-protected with RSV, as a vector to express the RSV fusion (F) glycoprotein as an RSV vaccine candidate. The RSV F ORF was codon optimized.

Prefusion HPIV F Immunogens and Their Use.

Human parainfluenza virus (hPIV) is an RNA-based paramyxovirus that causes respiratory infections in children and adults. There are four serotypes that can result in a myriad of diseases of the respiratory tract including croup, bronchitis, and pneumonia (Mao et al., 2012). hPIV is a leading cause of respiratory tract infection and hospitalization among children under 5, only surpassed by the respiratory syncytial virus (RSV). Currently, there are limited treatment options and no approved vaccines.

Glycan-masked engineered outer domains of HIV-1 GP120 and Their Use

The VRC01-class of potent, broadly neutralizing antibodies (bnAbs) targets the conserved CD4-binding site (CD4bs) of HIV-1 Env which has been a major target of HIV-vaccine design. The current best priming immunogen to engage the VRC01-class germline precursors is the eOD-GT8 60mer, which elicits VRC01-class precursors in multiple transgenic mouse models. However, a large proportion of the antibodies elicited by eOD-GT8 60mer are non-CD4bs or “off-target” antibodies, undermining its effectiveness in eliciting the VRC01-class bnAb precursors.
