A Novel Adeno-Associated Virus for Gene Therapy

Scientists at the NIH disclosed a novel adeno-associated virus (AAV) termed "44-9." AAV44-9 based vectors have high gene transfer activity in a number of cell types, including salivary gland cells, liver cells, and different types of neurons (e.g., cells of the cortex, olfactory bulb, and brain stem, and Purkinje cells of the cerebellum). These vectors can increase the transduction efficiency and decrease the potential of being neutralized by preexisting antibodies compared to the wild type AAV.

In-vivo System to Interrogate the Functions of Mucous Membranes and Identify Mucin/Glycan Mimetics and JAK/STAT Inhibitors for the Treatment of Diseases of the Oral Cavity and Digestive Tract

This technology includes a Drosophila mutant strain that can be used as an in vivo model for diseases of the oral cavity and digestive tract (Sjogren's syndrome, colitis, colon cancer, inflammatory bowel disease), where the mucous membrane is disrupted or non-functional. This mutant lacks a mucous membrane and displays epithelial cell damage, uncontrolled cell proliferation and the up-regulation of conserved signaling pathways (JAK/STAT).

Vitamin C renal leak as a clinical diagnostic tool in the detection, monitoring, and management of acute and chronic diseases

This technology includes a clinical diagnostic tool for measuring vitamin C elimination by human kidneys that can be used for detecting, monitoring, and managing acute and chronic diseases. Findings revealed significant associations between vitamin C renal leak status and clinical variables affecting renal function and blood glucose. The technology uses vitamin C depletion-repletion kinetics and pharmacokinetic models to establish a physiological vitamin C renal threshold.

Locally Delivered Alkaline Phosphatase for Treatment of Periodontal Disease

This technology includes a product for local delivery of alkaline phosphatase for the treatment of periodontal disease. Our laboratory has discovered that factors regulating phosphate metabolism and specifically the appropriate balance between phosphate (Pi) and pyrophosphate (PPi) at local sites are needed for formation (development), maintenance and regeneration of the tooth root surface (cementum), periodontal ligament (PDL) and surrounding alveolar bone, i.e., the periodontal apparatus.

Methods of Treating or Preventing Pruritis (Itch)

This technology provides a novel method of treating or preventing pruritis (itch) using natriuretic polypeptide b (Nppb) blocking agents. Itch (also known as pruritis) is a sensation that may be perceived as an unpleasant skin irritation and may drive an urge to scratch. Conditions such as, for example, psoriasis, atopic dermatitis, renal failure, liver cirrhosis and some cancers may cause persistent itch. Itch is triggered by somatosensory neurons expressing the ion channel TRPV1 (transient receptor potential cation channel subfamily V member 1).

A Novel Rapid Point-of Care Diagnostic Method for Infectious and Autoimmune Diseases

Rapid point-of-care, antibody-based testing is not available for the diagnosis of autoimmune and most infectious diseases. For detecting autoantibodies associated with most autoimmune conditions, fluid-phase immunoprecipitation assays are required. However, these assays usually involve radioactivity and are not feasible for point-of-care applications. The subject invention describes methods of using neodymium magnet for diagnosis of infectious and autoimmune diseases including lupus, Sjögren's syndrome, type I diabetes, HIV and Lyme disease.

Potential New Drugs for Treating or Preventing Pruritus

NIH scientists have identified new compositions that could potentially be used to treat or prevent pruritus (itchiness). The newly discovered compounds can block a newly identified itch pathway and might be effective for persistent itch caused by psoriasis, atopic dermatitis, renal failure, liver cirrhosis and chemotherapy. These compounds are different from commonly used antihistamines which induce drowsiness and sedation. These compounds have the potential to be used for human and animals.

KCNN4 Knockout Mice for Mechanistic Research

This technology includes a transgenic allele for a mouse knockout model for the KCNN4 gene. Secretion of fluids from these salivary glands requires the coordination of multiple water and ion channel proteins. Notably, the majority of these channels have been shown to be up-regulated by increased calcium concentrations. The relevant calcium-activated potassium channels are split into the small, intermediate, and large conductance channels (called the SK, IK, and BK channels). The KCNN4 gene plays a part in the IK and BK channels.

Polyclonal Antibodies to Apolipoprotein L1 for Use in Basic Science Research

This technology includes antibodies to apolipoprotein L1 (ApoL 1) to be used in basic science laboratory studies. ApoL 1 is a protein that is present within cells and circulates as component of high-density lipoprotein. Its functions are not well understood. Recently APOL 1 genetic variants have been shown to be highly associated with kidney disease in African Americans.
