NIH Inventors have recently discovered a novel Leucine-rich repeat and calponin homology domain-containing protein 4 (Lrch4) in a proteomic screen of the plasma membrane of lipopolysaccharide (LPS)-exposed macrophages. Expression data by RT-PCR revealed that all Lrch family members (1-4) are expressed in macrophages, but only Lrch4 was recruited into lipid rafts (signaling microdomains of the plasma membrane) by LPS. Lrch4 is the most highly expressed Lrch family member in mouse tissues. It is a predicted single-spanning transmembrane protein that is encoded by the Lrch4 gene in humans.

This molecular probe may serve as a companion tool to identify and stratify patient populations based on the prevalence of the target A₃ adenosine receptors.

Small molecule drugs, A₃AR-selective agonists, are currently in advanced clinical trials for the treatment of hepatocellular carcinoma, autoimmune inflammatory diseases, such as rheumatoid arthritis, psoriasis, and dry eye disease, and other conditions.

This technology provides novel antibodies and methods for diagnostics and treatment of disorders arising from dysregulation of the immune system using antibodies directed against glucocorticoid-induced tumor necrosis factor receptor family-related receptor ligand (GITRL). Also available are hybridomas producing anti-mouse GITRL monoclonal antibodies (clone 5F1).

This technology describes the use of novel mutated anthrax protective antigen (PA) protein variants to target tumor cells and tumor vasculature. NIH scientists have engineered two PA variants that selectively complement one another and combine to form active octamers that target tumor cells. This controlled oligomeric activation of the PA proteins makes the likelihood of toxicity to non-tumor cells very low since non-tumor tissue does not express certain cell-surface proteases required to activate the PA variants.

Due to the disorganized nature of blood vessels that run through tumors, chemotherapeutic agents often fail to penetrate tumors and kill cancer cells at the tumor’s center. This can lead to ineffective chemotherapeutic treatments, because tumors can quickly grow back if the entire tumor is not destroyed. NIH researchers have developed a therapeutic agent that solves this problem facing current chemotherapy treatments.

Our technology describes unique genetic signatures in patients with digestive diseases and liver disorders. Using comprehensive analysis of 735 microRNAs and 19,000 mRNAs, we have identified a unique set of microRNAs and/or mRNAs which predict disease phenotypes in patients with digestive and liver disorders. The identification of such point-of- care genetic signatures is significant for both personalized biomarkers and novel targeted biotherapeutics. These microRNAs and mRNAs function either together or separately thus modulating protein expressions in one or more signaling pathways.

Vaccines and therapies to prevent and treat Norovirus infections do not exist, despite the worldwide prevalence of Norovirus infections. Outbreaks of human gastroenteritis attributable to Norovirus commonly occur in group setting, such as hospitals, nursing homes, schools, dormitories, cruise ships and military barracks.

CDC researchers have developed methods of producing unlimited quantities of Group-C (GpC) rotavirus antigens. GpC rotaviruses are a major, worldwide cause of acute gastroenteritis in children and adults that is distinct from Group-A rotavirus. However, GpC rotaviruses cannot be grown in culture, resulting in a lack of tools for detection and treatment of GpC rotavirus disease.

CDC researchers have developed specific Respiratory Syncytial Virus (RSV) immunogens for use in the development of RSV-directed vaccines and therapeutics. RSV is the most common cause of serious respiratory disease in infants and young children and an important cause of disease in the elderly. To date, efforts to make a mutually safe and effective vaccine have been largely unsuccessful.

This CDC developed invention pertains to Streptococcus pneumoniae protein "pneumococcal fimbrial protein A (PfpA)," as well as the encoding pfpA gene. S. pneumoniae linked pneumococcal disease is prevalent among the very young, the elderly and also immunocompromised individuals. This invention covers the breadth of directly PfpA-related technology that might be employed for development of diagnostic tests for S. pneumoniae and/or vaccines directed against the pathogen.
