The global market for cancer therapeutics is over $40 billion and is anticipated to continue to rise in the future. There remains a significant unmet need for therapeutics for cancers that affect blood, bone marrow, and lymph nodes and the immune system, such as leukemia, multiple myeloma, and lymphoma. The proteasome inhibitor bortezomib, which may prevent degradation of pro-apoptotic factors permitting activation of programmed cell death in neoplastic cells dependent upon suppression of pro-apoptotic pathways, has been a successful mode of treatment for such cancers.

Monitoring an immune system that has been depleted by infection (e.g., HIV), chemotherapy, or progenitor cell transplantation is vital to assessing individual’s recovery status. This technology provides a new plasmid standard to be used as part of the existing TREC assay. This new plasmid has a shorter insert than the commercially available one, which means it now matches the PCR product generated in the qPCR reaction in the TREC assay. Additionally, the new plasmid is easier to grow up than the existing standard.

No vaccine candidates against Ebola virus (EBOV) or Marburg virus (MARV) are nearing licensure and the need to develop a safe and efficacious vaccine against filoviruses continues. Whereas several preclinical vaccine candidates against EBOV or MARV exist, their further development is a major challenge based on safety concerns, pre-existing vector immunity, and issues such as manufacturing, dosage, and marketability. The inventors have developed a new platform based on live or chemically inactivated (killed) rabies virus (RABV) virions containing EBOV glycoprotein (GP) in their envelope.

Early work by Hammond at al. showed gamma globulin to be effective for the prevention of poliomyelitis. Therefore, passive immunotherapy could be another way to treat chronic excretors. Even though prior attempts to use intravenous immunoglobulin (IVIG) and breast milk were unsuccessful, there is reason to think that higher doses of antipoliovirus antibodies could result in complete clearance of poliovirus from chronically infected individuals.

Cardiovascular disorders associated with endothelial dysfunction, like atherosclerosis, have decreased endothelial nitric oxide (NO) bioavailability. L-arginine, the primary substrate for endothelial nitric oxide synthase (eNOS), is important in the regulation of NO production. Arginase competes with eNOS for L-arginine and has been implicated in the endothelial dysfunction. NIH investigators have generated transgenic mice with human ArgII (hArgII) gene under control of endothelial-specific Tie2 promoter. In these mice, hArgII was expressed at very high levels in all tissues except liver.

TBEV causes serious illnesses from meningitis to meningo-encephalitis, totaling 3,000 cases of hospitalization in Europe and between 5,000-10,000 cases in Russia reported every year. The Far Eastern hemorrhagic TBEV strains are associated with a mortality rate (between 1-2%), higher than other strains isolated in the Siberia or Western Europe. There is a high proportion (up to 46%) of TBEV patients with temporary or permanent neurological sequelae.

The effort targeting the mosquito borne neglected tropical disease lymphatic filariasis for elimination through mass drug administration by 2020 will require accurate, cost effective methods for detecting early infections. The World Health Organization-recommended immunochromatographic test detects adult Wuchereria bancrofti (Wb) antigen in blood, but shows variable efficacy due to the complex life cycle of the parasites and cross reactivity with other organisms. This variability may hinder effective lymphatic filariasis elimination efforts.

Species of Bacillus, such as Bacillus anthracis, Bacillus cereus, and Bacillus subtilis, are attractive microorganisms for recombinant protein production in view of their fast growth rate, high yield, and ability to secrete produced products directly into the medium. Bacillus anthracis is also attractive in view of its ability to produce anthrax toxin and ability to fold proteins correctly. This application claims a B. anthracis strain in which more than one secreted protease is inactivated by genetic modification.

One of the primary means for treating HIV infection is the use of antiviral nucleotide or nucleoside analogs. These analogs work by inhibiting the activity of reverse transcriptase, the enzyme responsible for preparing the HIV genome for integration into the DNA of the host cell. Although these analogs do not have an effect on the polymerases responsible for replicating the human genome, the polymerase responsible for replicating the mitochondrial genome is sensitive to these analogs.

The invention is a STAT5 mutant mouse that can be used in research related to cancer, autoimmunity and infectious diseases as well as drug screening. The mouse model itself has multiple immunological defects resulting in formation of STAT5 dimers but not tetramers.
