Simian T-Cell Lymphotropic Virus Strain Type 3 (STLV-3) Subtype D Variant, a Highly Divergent STLV-3, for Development of Diagnostics, Therapeutics, Vaccines and Research Tools

Simian T-cell lymphotropic viruses (STLV) are nonhuman primate retroviruses closely related to the human T-lymphotropic virus (HTLV). Types I, II, and III of HTLV have been found in humans and are believed to have originated from cross-species transmission of STLV from infected nonhuman primates. The HTLV viruses are known to cause leukemia, lymphoma, and neurological disorders.

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.

P2Y14 Receptor Antagonists Containing A Biaryl Core

The technology discloses composition of compounds that fully antagonize the human P2Y14 receptor, with moderate affinity with insignificant antagonism of other P2Y receptors. Therefore, they are highly selective P2Y14 receptor antagonists. Even though there is no P2Y14 receptor modulators in clinical use currently, selective P2Y14 receptor antagonists are sought as potential therapeutic treatments for asthma, cystic fibrosis, inflammation and possibly diabetes and neurodegeneration.

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.

CRISPR-Mediated Gene Inhibition and Neuronal Differentiation in Human Induced Pluripotent Stem Cell (iPSC) Lines

This invention includes human induced pluripotent stem cell (iPSC) lines that harbor a single copy dCas9-BFP-KRAB at the CLYBL safe harbor locus (mediating CRISPR inhibition of human gene expression) and/or a single copy of dox-inducible NGN2 at the AAVS1 locus (enabling the differentiation of the iPSCs into neurons). The CRISPR-mediated inhibition of human gene expression is maintained into the differentiated neurons, permitting functional studies of targeted genes in neurons.

Murine Monoclonal Antibodies Effective To Treat Respiratory Syncytial Virus

Available for licensing through a Biological Materials License Agreement are the murine MAbs described in Beeler et al, "Neutralization epitopes of the F glycoprotein of respiratory syncytial virus: effect of mutation upon fusion function," J Virol. 1989 Jul;63(7):2941-2950 (PubMed abs). The MAbs that are available for licensing are the following: 1129, 1153, 1142, 1200, 1214, 1237, 1112, 1269, and 1243. One of these MAbs, 1129, is the basis for a humanized murine MAb (see U.S.

Hybridomas to Human Immunoglobulins for SARS-CoV-2 Diagnostics and Additional Indications

Immunoglobulins play a key role in the immune system. CDC has developed and tested hybridoma cell lines (monoclonal antibody (mAb) clones) for human IgG and other immunoglobulins. The mAbs generated from those hybridomas could be used as a reagent (second Ab) of anti-human immunoglobins in a diagnostic assay for SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), the virus that causes COVID-19 (coronavirus disease 2019) and other assays that detect antigen specific antibodies from human sera.

Highly Potent and Selective Deubiquitinating Enzyme Inhibitor

Available for licensing are inhibitors that target the USP1/ UAF1 deubiquitinating enzyme (DUB) complex. The FDA approval and commercial success of Velcade®, a small molecule proteasome inhibitor, has established the ubiquitin-proteasome system (UPS) as a valid target for anticancer treatment. However, proteasome inhibitors in general suffer from a narrow therapeutic index and acquired resistance. A promising alternative to proteasome inhibition has been to target the enzymes upstream of proteasome-mediated protein degradation, i.e.
