Methods for Using Modulators of Extracellular Adenosine or an Adenosine Receptor To Enhance Immune Response and Inflammation

Local inflammation processes are crucially important in the host defense against pathogens and for successful immunization because proinflammatory cytokines are necessary for initiation and propagation of an immune response. However, normal inflammatory responses are eventually terminated by physiological termination mechanisms, thereby limiting the strength and duration of immune responses, especially to weak antigens. The inventors have shown that adenosine A2a and A3a receptors play a critical role in down-regulation of inflammation in vivo.

Minibody for Conditioning prior to Hematopoietic Stem Cell and Progenitor Cell Transplantation

Patient conditioning is a critical initial step in hematopoietic stem and progenitor cell (HSPC) transplantation procedures to enable marrow engraftment of infused cells. Conditioning regimens have traditionally been achieved by delivering cytotoxic doses of chemotherapeutic agents and radiation. However, these regimens are associated with significant morbidity and mortality, and cannot be used safely in elderly or subjects with comorbidities.

Single Scan Bright-blood and Dark-blood Phase Sensitive Inversion Recovery (PSIR) Late Gadolinium Enhancement (LGE) for Cardiovascular Magnetic Resonance (CMR) Imaging

This technology includes a technique to improves detection of myocardial scar compared with conventional bright-blood late gadolinium enhancement (LGE) techniques. Dark-blood late gadolinium enhancement (DB-LGE) improves tissue delineation with signal suppression of the blood pool based on T2-preparation pulse that is relatively independent from the blood flow velocities and improves scar detection in patients with known or suspected coronary artery disease.

Potentiating Antibody Therapy for the Treatment of Cancer

This technology includes a strategy to target tumor cells that lost antigen following reaction with a therapeutic antibody by targeting the complement component C3d that has been deposited on target cells by the primary antibody. We previously generated a C3d-specific mouse/human chimeric antibody called C8xi and obtained proof of principle for the approach in two preclinical models. Here we summarize the generation of a new set of C3d targeting antibodies.

Peptide Mimotope Candidates for Otitis Media Vaccine

This technology describes peptide mimotopes of lipooligosaccharides (LOS) from nontypeable Haemophilus influenzae (NTHi) and Moraxella catarrhalis that are suitable for developing novel vaccines against the respective pathogens, for which there are currently no licensed vaccines. The mimotopes not only immunologically mimic LOSs from NTHi and M. catarrhalis but will also bind to antibodies specific for the respective LOS. NTHi and M. catarrhalis are common pathogens that cause otitis media in children and lower respiratory tract infections in adults.

Enhanced Single-Component AMA1-RON2 Vaccine Candidates: A Breakthrough in Malaria Immunization

This technology focuses on the creation of single-component AMA1-RON2 (Apical membrane antigen 1-rhoptry neck protein 2) vaccine candidates. These candidates are based on a novel composition of matter designed to elicit a more effective immune response against the malaria parasite Plasmodium falciparum. The standout aspect of this technology is the Structure-Based Design 1 (SBD1) immunogen, engineered through a structure-based design that significantly enhances its ability to produce potent, strain-transcending neutralizing antibodies.

Transgenic Mouse Models for Studying HLA-B57:01 and HLA-B15:02 Linked Immune Responses and Hypersensitivity Reactions

Transgenic mouse models expressing human HLA-B57:01 and HLA-B15:02 molecules have emerged as invaluable tools for unraveling the intricacies of immune responses and hypersensitivity reactions. The major histocompatibility complex (MHC) encoded proteins play a pivotal role in the immune system by presenting peptide fragments to T lymphocytes, and HLA-B57:01 has been associated with severe hypersensitivity reactions triggered by abacavir, a widely used anti-retroviral drug.

Targeted Gene Mutation Technology for Studying Specific Cell Functions in Mice

This technology includes the development of transgenic mice with a targeted gene mutation that flanks exon 8 of the Ikzf2 (Helios) gene using loxP sites. These Ikzf2 fl/fl (floxed) mice allow researchers to selectively delete the Ikzf2 gene in specific tissues or cells by crossing them with mice that express Cre recombinase under tissue-specific promoters.

Advancements in Postexposure Prophylaxis: Evaluating High-Potency Rabies-Neutralizing Monoclonal Antibodies

This technology represents a significant advancement in the field of rabies prevention, focusing on the development of highly potent rabies-neutralizing monoclonal antibodies (mAbs) for use in postexposure prophylaxis (PEP). With two mAbs, F2 and G5a, displaying exceptional neutralizing titers of 1154 and 3462 International Units (IUs) per milligram, respectively, these antibodies have the potential to offer enhanced protection against rabies when administered alongside rabies vaccines.

High Density Lipoprotein Targeting Protease Inhibitor Peptide for the Treatment of Alpha-1-antitrypsin (A1AT) Deficiency

This technology includes a novel concept and design for a lipoprotein targeting protease inhibitor for the treatment of Alpha-1-antitrypsin (A1AT) deficiency. A1AT deficiency occurs in about 1 in 2500 individuals in the United States and Europe, and people with this condition develop severe liver disease and emphysema/chronic obstructive pulmonary disease (COPD). Current treatment involves intravenous infusion of purified human A1AT protein, which is very expensive and only modestly effective.
