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.

This technology includes the enablement of the nanoliter-scale transfer of biological liquids in array format from a microplate (source plate) containing cultured cells or other protein-containing mixtures onto a nitrocellulose membrane that has been mounted within a custom-designed target plate. Using this method and the prototype nitrocellulose target plate, reverse phase protein arrays can be generated in which protein levels from each well transferred onto the membrane can be detected and quantified.

This technology includes a precise measurement assay of cellular FMRP levels in patients, which can assist in the diagnosis and assess the severity of Fragile X syndrome (FXS). FXS is an X-linked disorder that produces intellectual disability, cognitive impairment, epilepsy, depression and anxiety. FXS is caused by mutations in the Fragile X Mental Retardation-1 (FMR1) gene that result in the absence or a loss of function of its protein product, FMRP.

The invention is a panel of five tests of patient sera for immune responses that may attack the brain and lead to the characteristic symptoms of pediatric acute neurologic syndrome (PANS). PANS is a condition defined by a sudden onset of obsessive-compulsive symptoms, eating restrictions, and other cognitive and/or behavioral symptoms. Currently, the diagnosis of PANS is made when other possible symptoms are ruled out, a diagnosis of exclusion.

The invention relates to rabbit antisera raised against purified human chymotrypsin and amylase. Both chymotrypsin and amylase are produced by the pancreas and play important roles in digestion. Abnormal levels of chymotrypsin and amylase have been known to occur with multiple pancreas-related disorders, including pancreatitis. Measuring levels of these two enzymes using these polyclonal antibodies can help determine if a pancreas is functioning correctly.

This technology relates to the generation and use of an antibody that recognizes the S1459 phosphorylated site of the GRIN2A gene, which encodes the GluN2A subunit of the NMDA receptor. This gene is widely accepted as an epilepsy-causative gene and has been implicated in autism spectrum disorder (ASD). The S1459 phosphorylation site was selected based on an identified mutation in an epilepsy patient. This antibody can be used to specifically visualize the localization of the phosphorylated version of the GRIN2A protein product in the brain.

This technology includes the generation and use of an antibody that can detect endogenous Neuroligin 4Y, NLGN4Y, a cell adhesion molecule on the X-chromosome. NLGN4Y is part of an X-Y pair with NLGN4X, which has been implicated with autism spectrum disorder (ASD) and intellectual disability. ASD has a sex bias etiology that is not well understood, affecting four times as many males as females. Previous work has revealed a potential pathogenic mechanism for male-bias based on mutations in NLGN4X and NLGN4Y. The use of the NLGN4Y antibody could be used to study potential mechanisms.

This technology includes the creation and use of a mouse anti-Atlastin-1 monoclonal antibody (3194, IgG1). Mutations in Atlastin-1 are commonly found in hereditary spastic paraplegia, SPG3A. In addition, this protein is conserved in all eukaryotes, and it mediates fusion of endoplasmic reticulum tubules in cells, giving it its characteristic polygonal appearance. Thus, this protein is of interest to both those interested in disease pathogenesis and those studying basic cell biology.
