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.

During lung infection, bloodstream neutrophils (PMNs) responding to infection travel to the airspace lumen. Although successful arrival of microbicidal PMNs to the airspace is essential for host defense against inhaled pathogens, excessive accumulation of PMNs in the lung contributes to the pathogenesis of several prevalent lung disorders, including acute lung injury, bronchiectasis, and COPD. Unfortunately, there is no treatment for controlling PMN accumulation in the lung.

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.

Rotaviruses cause severe gastroenteritis in humans and animals globally. Currently, there are eight known serogroups (A-H) of rotaviruses. Group C rotavirus (GpC RV) causes sporadic cases and outbreaks of acute diarrhea in children and adults worldwide. GpC RV is also associated with diarrhea in swine. Currently, no simple and reliable diagnostic test exists for GpC RV, so disease prevalence remains unknown.

This invention includes the generation and use of two polyclonal antibodies that specifically recognizes the phosphorylation site pThr707 of Neuroligin 4 and pThr739 of Neuroligin 1. A peptide of the site around the phosphorylation site was generated and injected into rabbits to create an immune response. Serum was collected from the rabbits that was then affinity purified. The specificity of the resulting polyclonal antibodies was then determined using biochemical techniques.

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.

This technology includes a series of diphenylpropanamides as potent and selective RORgt inhibitors for the treatment of Th17-related autoimmune diseases. The retinoic acid-related orphan receptor RORgt plays an important role in the differentiation of thymocytes, lymphoid tissue inducer cells, and inflammatory T helper-expressing interleukin 17a (Th17) cells. Small molecule RORgt inhibitors may provide means to regulate Th17 mediated immune response. The novel molecules have potential to treat Th17-related autoimmune diseases.

This technology includes a strategy to generate antibodies of rabbit origin, both polyclonal and monoclonal, which have strong affinity to the TAT sequence and which enable specific immunocapture or immunodetection of TAT containing frataxin and analogs for quantitative or qualitative assays. In addition, antibodies that react with the FXN region have also been generated with this strategy. The HIV virus encoded a translational activator protein containing a 12 amino acid domain which permits transmembrane delivery of any therapeutic protein containing the sequence.
