Truncated (N)-Methanocarba Nucleosides as Al Adenosine Receptor Agonists and Partial Agonists: Receptor Docking and Potent Anticonvulsant Activity for the Treatment of Various Conditions

This technology includes A1AR-selective agonists which are full or partial agonists of the A1AR and are being considered for treatment of various conditions: seizures, stroke, diabetes, pain, cardio-protection and arrhythmias. A1AR agonists are highly neuroprotective in ischemic and epileptic models. A1AR agonists are also being explored for antidepressant, antianxiety, and other neuropsychiatric effects, due to their presynaptic action to decrease the release of excitatory amino acids in the brain.

Figla-Cre Transgenic Mice Expressing Myristoylated EGFP in Germ Cells as a Model for Investigating Perinatal Oocyte Dynamics

This technology includes a transgenic mouse model which can be used to study perinatal oocyte dynamics. In the first two days after birth, the number of primordial ovarian follicles and their germ cells undergo a major decrease. The mechanism for this decrease was studied. Ablation of FIGLA (Factor in the germline, alpha), a basic helix-loop-transcription factor, results in massive perinatal oocyte loss. A transgenic mouse line was established, Figla-EGFP /Cre, in which EGFP and Cre recombinase are expressed just before birth in germ cells.

Vectors for the Treatment of Sickle Cell Disease and Beta Thalassemia

This technology includes lentivirus vectors to be used to treat sickle cell disease and beta thalassemia. (i) Lin28A or Lin28B vectors designed for erythroid-specific expression using EKLF1, SPTA1, or similar erythroid-specific regulatory elements will be used to transduce hematopoietic stem cells isolated from humans with sickle cell disease or beta-thalassemia syndromes.

Transgenic Mice with Conditionally Activated Islet Beta Cell M3 Muscarinic Acetylcholine Receptor for Improving Glucose Tolerance in High-fat Diet Obese Insulin-resistant Mice

This technology includes transgenic mice in which designer rat M3 muscarinic receptor mutants were expressed only in islet 13-cells (directed by rat insulin promoter II), were unable to bind acetylcholine (the endogenous ligand) but could be selectively activated by an otherwise pharmacologically inert compound (clozapine-N-oxide (CNO)). The R-q receptor contained a Y148C point mutation, which enabled CNO to selectively activate G proteins of the Gq/11 family. The R-5 receptor contained an A238G mutation, which enabled CNO to selectively activate G proteins of the G5 family.

Identification and Characterization of the Wild Mouse Gut Microbiome as the Optimal Standard for Laboratory Mice

This technology includes identification of the wild mouse microbiome as a method to increase resistance to lethal viral infection. We establish that the gut microbiome of barrier-raised C57BL/6 mice is dysbiotic compared to that of their outbred, wild-living progenitors, Mus musculus domesticus. We find that the multigenerational offspring of pregnant germfree C57BL/6 mice reconstituted with the gut microbiome of wild mice exhibit a less inflammatory response and increased survival following influenza A virus infection.

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.

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.

Detection of Mutational Frequency in Human Bone Marrow

To date there have been no adequate methods to determine the frequency of mutations in humans. This invention discloses a method of measuring the mutational frequency of a mitochondrial DNA sequence by sequencing mitochondrial DNA from clonally expanded single cells such as CD34+ human stem cells. Sequencing for mitochondrial DNA polymorphisms and mutations may also be useful as a general method to detect minimal residual disease in leukemia. The mitochondrial genome is particularly susceptible to mutations and these may be used to measure genomic mutagenesis by virtue of comparison.
