Mouse Model for Study of Diabetic Nephropathy and Role of Soluble Epoxide Hydrolase

Diabetic nephropathy (DN) is the leading cause of renal failure and is characterized by proteinuria that progresses to renal inflammation and decline in the glornerular filtration barrier (GFB). Podocytes are specialized epithelia cells in the glomerular capsule that have a role in filtration of blood and maintaining the integrity of the GFB; dysfunction of these cells plays a significant role in the pathogenesis of DN. Soluble epoxide hydrolase (sEH) is a cytosolic enzyme whose inhibition has beneficial effects in inflammatory diseases.

Bag6 Polyclonal Antibodies That Recognize Human Bag6 Protein

Bag6 (BCL2 associated athanogene 6) is a multifunctional chaperone involved in tail anchored protein biogenesis, endoplasmic reticulum-associated protein degradation, and degradation of mislocalized membrane proteins. It is the central component of a stable three chaperone complex that also contains two cofactors-Ubl4A and Trc35. This complex acts in conjunction with the co-chaperone SGTA to channel proteins bearing an exposed hydrophobic segment in the cytosol to avoid protein aggregation.

Triazole Derivatives of 4,7-disubstituted 2 naphthoic acid (PPTN) as P2Y14 Receptor Antagonists

The Molecular Recognition Section of NIDDK announces the availability of a novel triazole-based probes, structures which act as antagonists at human P2Y14 receptors. Although the physiologic functions of this receptor remain undefined, recently it has been strongly implicated in immune and inflammatory responses. Prior work with a 4,7-disubstituted 2 naphthoic acid derivative (PPTN) established the ability to inhibit chemotaxis of human neutrophils in the lung and kidney.

Capsid-Free AAV Vectors for Gene Delivery and Their Use for Gene Therapy

The invention concerns novel capsid-free AAV vectors that can be used for gene delivery and gene therapy applications. The invention provides for a linear nucleic acid molecule comprising in this order: a first adeno-associated virus (AAV) inverted terminal repeat (ITR), a nucleotide sequence of interest, and a second AAV ITR, wherein said nucleic acid molecule is devoid of AAV capsid protein coding sequences. The said nucleic acid molecule can be applied to a host at repetition without eliciting an immune response.

Transgenic Mice Expressing CNO-sensitive Gq- or Gs-coupled Designer Receptors Selectively in Pancreatic Beta Cells

Impaired functioning of pancreatic beta cells is a key hallmark of type 2 diabetes. Beta cell function is modulated by the actions of different classes of heterotrimeric G proteins. The functional consequences of activating specific beta cell G protein signaling pathways in vivo are not well understood at present, primarily due to the fact that beta cell G protein-coupled receptors (GPCRs) are also expressed by many other tissues.

Polyvalent Influenza Virus-Like Particles (VLPs) and Use as Vaccines

Influenza virus is a major public health concern, causing up to 500,000 deaths annually. The current strategy of reformulating vaccines annually against dominant circulating strains leads to variable protective efficacy and is unlikely to protect against novel influenza viruses with pandemic potential. Thus, there is a great need for a vaccine that provides “universal” protection against influenza viruses.

Efficient mRNA-Based Genetic Engineering of Human NK Cells with High-Affinity CD16 and CCR7

A highly efficient method to genetically modify natural killer (NK) cells to induce expression of high affinity CD16 (HA-CD16) through mRNA electroporation, to potentiate NK cell-mediated antibody-dependent cellular cytotoxicity (ADCC). ADCC is mediated by CD16+ NK cells following adoptive NK cell transfer, but most humans express CD16 which has a relatively low affinity for IgG1 antibodies.

Pyrophosphate Analog HIV-1 Reverse Transcriptase Inhibitors

The invention relates to compounds that inhibit HIV-1 DNA synthesis mediated by reverse transcriptase (RT). HIV-1 DNA synthesis by RT utilizes deoxynucleoside 5’-triphosphate (dNTP) as substrate and like many other enzymes, the reaction is reversible. Pyrophosphate analogs like imidodiphosphate strongly promote reverse reaction dNTP products containing the imidodiphosphate group instead of the naturally occurring pyrophosphate group. This imidodiphosphate-containing dNTP was found to be a potent inhibitor of the forward RT reaction.

Development of a Transferrable Norwalk Virus Epitope and Detector Monoclonal Antibody

Noroviruses are now recognized as the major cause of non-bacterial gastroenteritis in all age groups, and efforts are underway to develop an effective vaccine. The lack of a robust cell culture system for human noroviruses has complicated vaccine development. Hence, norovirus virus like particles (VLPs) have played an important role in the understanding of virus structure, immune response, antigenic diversity, and vaccine design.

Novel Magnetic Resonance Spectroscopy (MRS) Technique to Quantify Brain Metabolites

With respect to quantification of metabolites in the brain, conventional methods of magnetic resonance spectroscopy (MRS) yield results that are highly variable and highly dependent on the sequence type being applied. This invention describes a novel MRS technique that involves preparing longitudinal steady states at different flip angles using trains of RF pulses interspersed with field gradients to quantify metabolites.
