Pyruvate Kinase M2 Activators for the Treatment of Cancer
This technology describes a series of small-molecule activators of the pyruvate kinase M2 isoform (PK-M2).
Identification and Use of 12/15-Lipoxygenase (LOX) Inhibitors for Post-Strike Treatment
This technology includes the identification and use of 12/15-lipoxygenase (LOX) inhibitors, including ML351 and related analogs, for post-stroke treatment. The 12/15-LOX directly oxidizes lipid membranes leading to their direct attack. After a stroke, the activity of 12/15-LOX is upregulated and is thought to contribute to increased neuronal loss and blood-brain barrier leakage. A high-throughput screen was undertaken to find inhibitors, which were then subjected to medical chemistry optimization.
SARS-CoV-2 Pseudotyping Plasmids for Cutting-Edge Studies
NIAID scientists have developed plasmids that allow for production of pseudoviruses expressing SARS-CoV-2 spike protein. As SARS-CoV-2 is a lethal airborne virus, it must be handled in high-containment Biosafety Level 3 (BSL-3) laboratories that require strict airflow, ventilation and decontamination procedures.
Transgenic Mouse Models for Studying HLA-B57:01 and HLA-B15:02 Linked Immune Responses and Hypersensitivity Reactions
Transgenic mouse models expressing human HLA-B57:01 and HLA-B15:02 molecules have emerged as invaluable tools for unraveling the intricacies of immune responses and hypersensitivity reactions. The major histocompatibility complex (MHC) encoded proteins play a pivotal role in the immune system by presenting peptide fragments to T lymphocytes, and HLA-B57:01 has been associated with severe hypersensitivity reactions triggered by abacavir, a widely used anti-retroviral drug.
Compounds and Methods for Treating Brain Injury
This technology includes MRS4322, which is an A3 agonist that is currently being evaluated for treatment of traumatic brain injury. Although its affinity in the receptor is in the micromolar range, it enters the brain in sufficient concentration to activate a protective CNS receptor, A3 adenosine receptor. Potential applications of such A3 agonists could also include neurodegenerative conditions.
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.
WNT1-Induced Secreted Protein-1 Knockout Mouse Model
WNT1-induced secreted protein-1 (WISP1) is expressed at high levels in osteoblasts and their precursors. WIPS1 plays an important role in various aspects of bone formation. Scientists at the NIH generated Wisp1-deficient (Wisp1-/-) mice. Deletion of Wisp1 resulted in a decrease in bone mineral density, total bone volume, bone thickness, and biomechanical strength.
Diagnostic Test and Therapeutic Target for Sjogren's Syndrome
Sjögren's syndrome is an autoimmune disease that attacks salivary glands resulting in chronic dry mouth and dry eyes. Currently, there is no single diagnostic test to confirm the presence of Sjögren's. Physicians presently reach diagnosis after conducting a series of blood and functional tests for tear and salivary production. Diagnosis is further complicated as Sjögren's symptoms frequently mimic those of other autoimmune diseases (e.g., lupus, rheumatoid arthritis, etc.) and is often overlooked as dryness associated with medications being taken by the patient.
A Mouse Model for Human Osteoarthritis
Osteoarthritis (OA) is the most common form of arthritis and affects more than 20 million Americans, costing billions of dollars in health care annually. Osteoarthritis is caused by the breakdown of joint cartilage, leading to a loss of the cartilage "cushion" between the bones of the joints. Risk factors associated with OA include age, obesity, traumatic injury and overuse due to sports or occupational stresses. There is no cure for OA and current treatments are directed at the symptomatic relief of pain, and at improving and maintaining joint function.
Regenerative Therapy for Cartilage Damage
The subject technology discloses a tissue engineering method for treating cartilage damage. Stem cells from bone marrow are attached to a novel scaffold, hyaluronic acid-coated fibrin microbeads, and transferred to a live host to form cartilage. The regenerated cartilage is stable and not hypertrophic, which has been problematic in the current regenerative methods.
