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.

The technology relates to a protein-based nanoparticle platform that allows presentation of immunogenic molecules such as influenza virus antigens. This protein platform is made up of hepatitis B capsid/core proteins. The core proteins contain immunogenic loop c/e1, where other antigens can be inserted and the chimeric protein retains the ability to form capsid-like particles. The technology describes the insertion of one or more copies of influenza epitopes derived from the globular head or the stem region of hemagglutinin protein into or around the c/e1 loop of the core protein.

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.

Coronaviruses (CoVs) can cause severe respiratory disease with high fatality rates in humans. The 2002-2003 SARS-CoV epidemic resulted in 8098 cases and 744 deaths, and MERS-CoV, which emerged in 2012, has resulted in 2144 cases and over 750 deaths as of March 2018. Currently, there are no effective prophylactic or therapeutic measures, and because other CoVs are poised to emerge as new human pathogens, there is a need to define a general CoV vaccine solution.
