Background-Free Fluorescent Nanodiamond Imaging

Available for licensing and commercial development are intellectual property rights covering a method of imaging a biological specimen (e.g., human tissue) using fluorescent nanodiamonds implanted into the subject of interest, applying a magnetic field to said subject and producing a resultant image by a net juxtaposition of a second acquired image. This process suppresses the background and permits selective imaging of the nanodiamonds in the presence of background fluorescence that exceeds the signal from the nanodiamonds.

T Cell-Based Adoptive Transfer Immunotherapy for Polyomavirus-Associated Pathologies

Available for licensing are methods to generate T cells responsive to multiple polyomaviruses. The resulting T cell populations could be useful in treating immunosuppressed individuals with polyomavirus infections or polyomavirus-associated pathologies such as Merkel cell carcinoma (MCC), polyomavirus-associated nephropathy (PVAN), hemorrhagic cystitis, progressive multifocal leukoencephalopathy (PML), and trichodysplasia spinulosa (TS). The methods could also be used to restore polyomavirus-specific immunity in immunocompromised individuals.

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.

Use of the Intracellular Signaling Domain of Receptor CD28H as a Component of Chimeric Antigen Receptors to Overcome Inhibition of Cytotoxic Lymphocytes by Checkpoint Receptors

Engineered chimeric antigen receptors (CARs) that are expressed in cytotoxic T cells and natural killer (NK) cells have been used to specifically target tumor cells. However, CAR-T and CAR-NK cells are still subject to down regulation by their inhibitory receptors after injection into patients.

TRIAZOLE DERIVATIVES AS P2Y14 RECEPTOR ANTAGONISTS

The technology describes the composition of small molecule compounds that are antagonists of the P2Y14 receptor. Also provided are methods of using the compounds, including a method of treating a disorder, such as inflammation, diabetes, insulin resistance, hyperglycemia, a lipid disorder, obesity, a condition associated with metabolic syndrome, and asthma, and a method of antagonizing P2Y14 receptor activity in a cell.

The Use of Metarrestin for the Treatment of Pancreatic Cancer

This technology includes the use of the small molecule metarrestin (ML246) for the treatment of several types of pancreatic cancer. A subcellular structure called the perinucleolar compartment (PNC) is frequently found in metastatic tumors and cancer stem cells. Reduction of PNC prevalence followed by medicinal chemistry was used to identify metarrestin as a compound that reduces PNC prevalence without significantly impacting cell viability. In vitro and in vivo animal work have demonstrated desirable pharmacokinetic properties as well as a reduction in metastatic burden and extended survival.

Potentiating Antibody Therapy by Targeting Complement Deposited on Cancer Cells

Monoclonal antibodies (mAbs) have become a mainstay of therapy for many cancers. However, antibody therapy is not completely effective in some applications due to loss of the target surface antigen on cancer cells. Such mAb-induced “escape variants” are no longer sensitive to the therapeutic mAb therapy. It was observed that the escape variants carried covalently bound complement activation fragments, especially C3d. NIH inventors have generated several C3d-specific mouse and rabbit monoclonal antibodies to re-target cells that have escaped from mAb therapy.

Identification and Use of Heterocyclic Alcohol Compounds for the Treatment of SULT1A1-expressing Cancers

This technology includes the identification and use of heterocyclic alcohol compounds, including RITA and N-BIC, for the treatment of SULT1A1-expression cancers. A high-throughput screen (qHTS) was performed using >1,000 caner cell lines identified a compound called YC-1 (also called Lificiguat) that is effective across cancer cell types that express the phase 2 detoxifying enzyme SULT1A1.

Potency Assay for Membrane Transporter Protein-based Drugs Acting on Antioxidant, Redox, and Apoptosis Response Pathways

This technology includes a method of analyzing the potency of membrane transporter protein-based drugs acting on intracellular antioxidant and redox response pathways (and associated apoptosis pathways), wherein the drug delivery and activity is lipid associated. The present invention is a cell-based bioassay for measuring the bioactivity of drug substance and formulated drug product by determining the drug's dose-dependent inhibitory effects on 4 hydroxynonenal (4-HNE)-induced antioxidant response element (ARE) activity.

A Novel Oxygen-induced Expression Vector for Production of Recombinant Proteins in Escherichia Coli

This technology includes a new method to induce recombinant protein expression in E. coli through the activating the SoxS promoter by molecular oxygen. We previously discovered that the SoxRS regulon of E. coli is activated in response to elevated dissolved oxygen concentration mainly to protect the bacteria from possible oxygen damage. We hypothesized that the 16-fold increase in the expression of this regulon make it possible candidate for inducing the expression of recombinant proteins.
