Mouse Models of Cryopyrin-Associated Periodic Syndrome (CAPS) for Drug Discovery

This technology includes mouse models that express versions of mouse cryopyrin protein containing mutations associated with human CAPS disease. We engineered mutations associated with three specific CAPS phenotypes (familial cold autoinflammatory syndrome (FCAS); Muckle-Wells syndrome (MWS); and neonatal onset multisystem inflammatory disease (NOMID)) into the mouse cryopyrin gene (called Nlrp3) to examine the roles of IL-1 β and related cytokines, and better characterize inflammasome functions.

Modified Bacterial Strain for Otitis Media Vaccine

This invention relates to a strain of Moraxella catarrhalis containing a gene mutation that prevents endotoxic lipooligosaccharide (LOS) synthesis and potential use of the mutant for developing novel vaccines against the pathogen, for which there is currently no licensed vaccine. M. catarrhalis is one of the causative agents of otitis media (middle ear infection), sinusitis, and lung infections. The mutant is defective in the lpxA gene, whose enzyme product is relevant in lipid A biosynthesis (lipid A is part of the LOS).

Tristetraprolin (TTP) Knockout Mice

National Institutes of Health researchers have developed knockout mice that do not express Tristetraprolin (TTP). TTP is an AU-rich element (ARE) binding protein and the prototype of a family of CCCH zinc finger proteins. AREs were identified as conserved sequences found in the 3’ untranslated region (3’ UTR) of a variety of transiently expressed genes including early response genes, proto-oncogenes, and other growth regulatory genes. AREs function as instability sequences that target ARE-containing transcripts for rapid mRNA decay.

TTP as a Regulator of GM-CSF mRNA Deadenylation and Stability

The disclosed invention provides materials and methods to treat granulocytopenia (low white cell count in the blood) which is characterized by a reduced number of granulocytes (relative) or an absence of granulocytes (absolute). This condition is commonly associated with cancer chemotherapy, but is seen less frequently in a number of conditions including the use of propylthiouracil, radiotherapy for marrow ablation for bone marrow transplantation, aplastic anemia, systemic lupus erythematosus, AIDS and a variety of other situations.

Methods and Materials for Identifying Polymorphic Variants, Diagnosing Susceptibilities, and Treating Disease

This invention relates to materials and methods associated with polymorphic variants in two enzymes involved in folate-dependent and one-carbon metabolic pathways important in pregnancy-related complications and neural tube birth defects: MTHFD1 (5,10-methylenetrahydrofolate dehydrogenase, 5,10-methenyltetrahydrofolate cyclohydrolase, 10-formyltetrahydrofolate synthase) and methylenetetrahydrofolate dehydrogenase (NADP+ dependent) 1-like (MTHFD1L). These enzymes are extremely important in the promotion of DNA synthesis, a process that is critical for normal placental and fetal development.

Molecules for Studying Cellular Immune Responses to Vaccines and Therapeutics

HLA molecules are indispensable and invaluable tools for efficient vaccine research and development. Infectious diseases are the second leading cause of death among adults and the most prominent cause of death in infants and children worldwide. Thus, rapid availability of prophylactic vaccines for cancers and infectious diseases such as HIV, HPV, influenza and diarrheal and respiratory diseases is a world-wide health concern.

Model for Study of Glomerular Disorders: Conditionally-Immortalized Mouse Podocyte Cell Line with Tet-on-Regulated Gene Expression

Podocytes, cells of the visceral epithelium in the kidneys, are a key component of the glomerular filtration barrier. As such, they play a vital role in glomerular disorders, which are a major cause of chronic kidney disease. Examples of these disorders include focal segmental glomerulosclerosis, membranous glomerulonephritis, minimal change disease, and diabetic nephropathy.

Aquaporin 2 Polyclonal Antibodies

Aquaporins, also known as water channels, form pores in cell membranes and selectively transport water in and out of the cell. Aquaporins are involved in regulation of water balance and blood pressure, and thirteen different isoforms have been found in mammals. Aquaporin 2 (AQP2) is located in the collecting duct of the kidney, and is regulated by the peptide hormone vasopressin. AQP2 expression is increased in conditions where there is water retention, such as pregnancy and congestive heart failure, and mutations of AQP2 are associated with nephrogenic diabetes insipidus.

Mouse Monoclonal Antibody to the Nitrone Spin Trap 5,5-dimethyl-1-pyrroline N-oxide (DMPO)

Oxidative stress resulting in the formation of biological radicals has been implicated in a number of human diseases, such as cancer as well as aging. There is, however, a paucity of reliable methods for in vivo or ex vivo detection of radical formation. Until now the only general technique that allowed for the detection of these highly reactive species was electron spin resonance (ESR) using spin traps. One of the most popular of these spin traps is 5,5-dimethyl-1-pyrroline N-oxide (DMPO).
