Antigen Mixtures for Serological Detection of HHV-8 Infection

This invention describes a highly specific and sensitive serological test for human herpesvirus 8 (HHV-8) infection that uses the Luciferase Immunoprecipitation System (LIPS). A mixture of four virus-specific antigens, including K8.1, v-cyclin, ORF65 and LANA, was shown to provide more robust detection of HHV-8 infection than traditional methods due its ability to detect very low viral loads.

Simple, Quantitative Sensitive High-throughput Antibody Detection for Lyme Disease

This technology is for compositions and methods for diagnosis of Lyme disease. Currently, Lyme disease is diagnosed by clinical exam and a history of exposure to endemic regions. Although, laboratory tests may aid diagnosis, the best tests currently available are slow and labor intensive and require understanding of the test, and infection stage. A two-step antibody based test process is currently the recommended laboratory test. The first step is either an enzyme immunoassay (EIA), or an indirect immunofluorescence assay (IFA).

Recombinant NIE Antigen from Strongyloides stercoralis

Strongyloides stercoralis is an intestinal nematode endemic that affects an estimated 30 to 100 million people worldwide. Many of these individuals may be asymptomatic for decades. The present invention discloses a NIE recombinant antigen that can be used in improved assays and diagnostics for S. stercoralis infection. The NIE antigen is the only one that is non-cross-reactive with sera from humans with other related filaria infections. The NIE antigen can be utilized as a skin test antigen for immediate hypersensitivity as well as for use in ELISA or other assays.

Mouse Lacking the Chemokine Receptor CX3CR1

This mouse has been generated by targeted gene disruption. The mouse provides a model to investigate the function of the chemokine receptor CX3CR1, which is a proinflammatory receptor for the leukocyte chemoattractant CX3CL1 (aka fractalkine). As an example, the mouse is in use in the study of atherosclerosis. Further, the mouse may serve as a model study the role of the immune system during infection with pathogens as well as other immunologically mediated diseases and responses to tumors.

Mouse Anti-Mouse CXCL9 (Mig) Monoclonal Antibodies

This technology describes monoclonal antibodies against mouse chemokine (C-X-C motif) ligand 9 (CXCL9), also known as Monokine induced by gamma interferon (Mig). CXCL9 is a secreted protein that functions to attract white cells and increased expression of CXCL9 has been linked to several diseases. The inventors at the NIH generated over 100 anti-mouse CXCL9 antibodies from a CLXL9/Mig knockout mouse and further characterized several antibodies to show neutralization of CXCL9.
