Postnatal Stem Cells and Uses Thereof

Many individuals with ongoing and severe dental problems are faced with the prospect of permanent tooth loss. Examples of such dental problems include: dentinal degradation due to chronic dental disease (caries or periodontal); mouth injury; or through surgical removal, such as with tumors associated with the jaw. For many, a technology that offers a possible alternative to artificial dentures by designing and transplanting a set of living teeth fashioned from an individual's own pulp cells would greatly improve their quality of life.

Oral Treatment of Hemophilia

This invention portrays a simple method for treatment of antigen-deficiency diseases by orally administering to a subject a therapeutically effective amount of the deficient antigen, wherein the antigen is not present in a liposome. This method increases hemostasis in a subject having hemophilia A or B, by orally administering to the hemophiliac a therapeutically effective amount of the appropriate clotting factor, sufficient to induce oral tolerance and supply exogenous clotting factor to the subject.

Application of AAV44.9 Vector in Gene Therapy for the Inner Ear

This technology includes a novel AAV isolate (AAV44.9) to be used as gene therapy for the inner ear for the treatment of deafness. The ability of AAV vectors to transduce dividing and non-dividing cells, establish long-term transgene expression, and the lack of pathogenicity has made them attractive for use in gene therapy applications. Vectors based on new AAV isolates may have different host range and different immunological properties, thus allowing for more efficient transduction in certain cell types.

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).

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).

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.

Treatment of Periodontal Disease via ENPPI Inhibition

This technology focuses on enhancing cementum production, a key component in treating periodontal regression. The method involves inhibiting ectonucleotide pyrophosphatase phosphodiesterases (ENPP1), enzymes that play a significant role in mineralization processes. Pyrophosphate (PPi) is known to impede the growth of hydroxyapatite crystals, essential for mineralization. ENPP1 catalyzes the hydrolysis of ATP, generating PPi, which then hinders mineralization.
