Soluble Antigen-Based ELISA for the Detection of B. malayi Infections

The technology presented is a breakthrough in the diagnosis of lymphatic filariasis, specifically targeting the B. malayi pathogen. It encompasses a novel soluble antigen extract used in both IgG and IgG4-based ELISA tests, aimed at detecting the presence of the filarial infection. This innovation serves as a cornerstone for a CLIA-certified reference test, established and utilized in Dr. Nutman's laboratory since the late 1980s.

Polyclonal and Monoclonal Antibodies to Human Eosinophil Major Basic Protein, Eosinophil Peroxidase, Eosinophil Cationic Protein, and Eosinophil-Derived Neurotoxin

Reagents particularly useful in configuring multiplex assays for simultaneous measurement and quantification of multiple eosinophil granule proteins and for immunohistochemistry. Ultimately these reagents may be used as diagnostics for many eosinophil-mediated disorders.

Methods for Treating or Ameliorating Fibrosis by Inhibiting the Interaction between IL-21 Receptor (IL-21R) and IL-21

This invention includes methods for treating or ameliorating fibrosis by inhibiting the interaction between IL-21 Receptor (IL-21R) and IL-21 using either anti-IL-21R monoclonal antibodies (or binding fragments of anti-IL-21R mAbs), anti-IL-21 monoclonal antibodies (or binding fragments of anti-IL-21 mAbs) or soluble IL-21R (or binding fragments of IL-21R). It is believed that the TH2 immune response, induced by IL-21, plays a major role in the in the pathogenesis of tissue fibrosis.

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.

Tissue Clamp for Repeated Opening and Closure of Incisions/Wounds

Medical clamps currently available are not efficient nor are they sufficiently precise in closure and alignment of the edges of an incision or wound. Many available designs are difficult to use and handle, especially in situations where repeated opening and closure of an incision or wound is required. The functional short-comings of existing clamp designs may result in surgical complications, such as excess loss of fluids and pressure and hemostasis during some procedures.

3-o-sulfo-galactosylceramide Analogs for Targeting Lung Metastases

Summary:

Lung metastases represent a major clinical challenge in advanced cancer, with poor survival rates and no effective therapies to prevent their development. Researchers at the National Cancer Institute (NCI) have developed C24:2, a first-in-class synthetic 3-O-sulfo-galactosylceramide analog. After lysosomal processing by dendritic cells, C24:2 switches immune specificity to activate type I NKT cells, triggering a potent IFN-γ–mediated Th1 response.

Gene Therapy for Treatment of CRX-Autosomal Dominant Retinopathies

Mutations in the cone rod homeobox (CRX) transcription factor lead to distinct retinopathy phenotypes, including early-onset vision impairment in dominant Leber congenital amaurosis (LCA). Adeno-Associated virus (AAV) vector-mediated delivery of a CRX cDNA under the control of a CRX promoter region partially restored photoreceptor phenotype and expression of phototransduction genes in an in vitro model of CRX-LCA.

Induced Pluripotent Stem Cells Derived from Patients with CEP290-associated Ciliopathies and Unaffected Family Members

Approximately one-third of non-syndromic retinal dystrophies involve a defect in a ciliary protein. Non-syndromic retinal ciliopathies include retinitis pigmentosa, cone dystrophy, cone-rod dystrophy, macular dystrophy, and Leber-congenital amaurosis (LCA). Many CEP290-LCA patients also exhibit auditory and olfactory defects. Induced pluripotent stem cells (iPS) cells were derived from patients with LCA and unaffected relatives. 
The National Eye Institute (NEI) seeks research collaborations and/or licensees for the use of these iPS cells.
