ELISA-Based Biodosimeter for Measuring and Quantifying DNA Damage
Summary:
The National Cancer Institute (NCI) seeks co-development partners and/or licensees to further develop a novel ELISA-based biodosimeter.
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.
Mice Genetically Deficient in the Chemoattractant Receptor FPR (formyl peptide receptor)
The present research tool is a knockout mouse model (FPR-/-) that lacks the high affinity N-formylpeptide receptor (FPR), created by targeted gene disruption.
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.
Human CCR3 cDNA
A plasmid encodes human C-C motif chemokine receptor 3 (CCR3). It may contribute to the accumulation and activation of eosinophil and other inflammatory cells in the allergic airway.
Treatment and Prevention of Inflammatory Bowel Disease (IBD) using Mutant and Chimeric IL-13 Molecules
Ulcerative colitis (UC) is a chronic inflammatory disease of the colorectum and affects approximately 400,000 people in the United States. The cause of UC is not known, although an abnormal immunological response to bacterial antigens in the gut microflora is thought to be involved. Present treatments for UC include anti-inflammatory therapy using aminosalicylates or corticosteroids, as well as immunomodulators and diet.
Muramyl Dipeptide as a Therapeutic Agent for Inflammation
The nucleotide-binding oligomerization domain 2 (NOD2) protein plays a key role in innate immunity as a sensor of muramyl dipeptide (MDP), a breakdown product of bacterial peptidoglycan. Bacterial peptidoglycan promotes the innate immune response through the activation of Toll-like receptor 2 (TLR2), which ultimately provokes inflammation. Activation of NOD2 by MDP negatively regulates the activity of TLR2, and thus reduces inflammation.
High Relaxivity Mulitivalent Gadolinium on a Peptide Scaffold for Targeted MRI Applications in Disease Diagnosis
This technology includes a peptide containing alternating Alanine and Lys(DOTA-Gd) residues can be used to increase the MRI relaxivity of a peptide. The low molecular weight construct can be appended to proteins, antibodies and peptides to increase MRI signals. This approach offers advantages over previous dendrimeric constructs.
qPCR Assay for Detection of JC Virus
JC Virus causes a fatal disease in the brain called progressive multifocal leukoencephalopathy (PML) that occurs in many patients with immunocompromised conditions. For example, more than five percent (5%) of AIDS patients develop PML. Additionally, these conditions include, but are not limited to, cancers such as leukemias and lymphomas, organ transplants such as kidney, heart and autoimmune conditions with treatment that modulates the immune system such as Multiple Sclerosis (MS), rheumatoid arthritis, psoriasis, and systemic lupus erythematosus.
Monoclonal Antibodies that Bind Zika Virus Envelope Protein for Zika Diagnostics and Research
Zika virus infection during pregnancy can cause microcephaly and other severe birth defects. The CDC Zika MAC-ELISA (IgM antibody capture enzyme-linked immunosorbent assay) currently used for diagnosis detects antibodies produced to fight a Zika virus infection. However, reactivity of flavivirus antibodies (from exposure to other mosquito-borne infections such as dengue or West Nile virus) can complicate the interpretation of these results.
