Stable, Early-stage Biomarker for Diagnosis of Bacillus anthracis Infection and Anthrax Vaccine Development

This invention comprises monoclonal antibodies, proteins, and related nucleic acid coding sequences that identify all or part of the antigenic anthrose oligosaccharide of Bacillus anthracis, the causative agent of anthrax toxicity in humans. It is imperative to identify virulent B. anthracis with speed and specificity, however there presently is substantial difficulty in early-stage recognition and diagnosis of anthrax inhalation.

CD40 Ligand: Adjuvant for Enhanced Immune Response to Respiratory Syncytial Virus

CDC researchers have developed methods and adjuvants for enhancing a subject's immune response to respiratory syncytial virus (RSV) by inclusion of a CD40 binding protein. RSV has long been recognized as a major respiratory tract pathogen of infants, as well as older children and the elderly. Established, successful methods for preventing RSV are currently unavailable. CD40 ligand (CD40L, also known as CD154) is an important costimulatory molecule found on the T-cell and is critical for the development of immunity.

Novel Targets to Prevent Borrelia burgdorferi Infection and Lyme Disease

B. burgdorferi-infected ticks can cause Lyme disease in mammalian hosts. This technology relates to the use of B. burgdorferi outer surface proteins (BBA64 and BBA66) as Lyme disease vaccine candidates. In vivo animal studies demonstrate these outer surface proteins inhibit tick-to-host B. burgdorferi transmission. Presently, there is no vaccine approved for Lyme disease.

Genome Wide DNase I Hypersensitive Sites Detection in Formalin-Fixed Paraffin-Embedded Single Cells

A method of detecting DNase I hypersensitive sites ((DHS) in a single cell or very small number of cells, including cells recovered from formalin-fixed paraffin-embedded (FFPE) tissue slides of patient samples. DHS has revealed a large number of potential regulatory elements for transcriptional regulation in various cell types. The application of DNase-Seq techniques to patient samples can elucidate pathophysiological mechanisms of gene function in a variety of diseases as well as provide potentially important diagnostic and prognostic information.

2,2'-Bipyridyl, a Ferrous Chelator, Prevents Vasospasm in a Primate Model of Subarachnoid Hemorrhage

Subarachnoid hemorrhage (SAH) occurs in 28,000 people per year in North America. Symptomatic vasospasm occurs in the majority of individuals suffering SAH and is the most common cause of morbidity and mortality in patients reaching neurological care. Specifically, vasospasm causes cerebral ischemia or stroke, and the prevention of vasospasm could prevent stroke and death as well as allow physicians more freedom in scheduling surgery when the operative risks are lower.

Fluorescent Nanodiamonds as Fiducial Markers for Microscopy

The invention relates to fluorescent nanodiamonds (FNDs) and their uses as fiducial markers for microscopy. FNDs are bright fluorescent probes that do not blink or bleach and have broad fluorescence excitation and emission peaks. The fluorescence intensity can be readily controlled by the size of the FND, the number of fluorescent centers produced in the nanodiamonds, or in situ through the application of a weak magnetic field.

Clones Encoding Mammalian ADP-Ribosylarginine Hydrolases

ADP-ribosylation of arginine residues in proteins may be involved in cell adhesion and is crucial for the action of cholera toxin and E. coli heat-labile enterotoxin, agents involved in the pathogenesis of cholera and traveller's diarrhoea, respectively. ADP-ribosylation is reversed by ADP-ribosylarginine hydrolases, which cleave the ADP-ribose-arginine bond. ADP-ribosylarginine hydrolases from a variety of mammalian species and tissues were isolated, and the coding regions for the hydrolases were cloned and expressed.

Cell Expansion System For Use In Neural Transplantation

Cell transplantation therapy typically involves transplanting primary cells or immortalized cells into patients. The promising but still inconsistent data stemming from those clinical trials using primary cells in Parkinson's disease are believed to be due to an insufficient number, function and uniformity of the transplanted cells. In an effort to overcome these problems an improved method for isolating, growing and differentiating precursor cells into dopaminergic neurons has been developed.

Vitamin D Receptor Antagonists for Treating Breast Cancer

Vitamin D receptor (VDR) is a nuclear receptor that is activated by calcitriol, the active form of vitamin D. It is best known for regulating dietary calcium uptake necessary for bone growth, but it also affects cell proliferation and differentiation. Therefore, it was thought that treatment with calcitriol or its derivatives could be useful to treat the uncontrolled proliferation typical of cancer cells. However, this approach has been unsuccessful to date because it leads to toxic levels of calcium in the blood.

Specific Inhibition of Gene Expression by Small Double Stranded RNAs

Double-stranded RNA (dsRNA) has been shown to trigger sequence-specific gene silencing in a wide variety of organisms, including plant, nematode and invertebrate species. Recent intense work in the field has shown that small dsRNAs mediate sequence specific RNA degradation in the process known as RNA interference (RNAi).

This invention provides for synthetic dsRNAs (20-25 nucleotides in length) and methods that can inhibit gene-specific expression in mammalian cells.
