Many potential nucleic acid therapeutics have not transitioned from the research laboratory to clinical application in large part because delivery technologies for these therapies are not effective. Most nucleic acid delivery technologies are lipid-based or positively charged and require chemical or physical conjugation with the nucleic acid. These delivery systems are often therapeutically unacceptable due to toxicity or immune system reactivity.

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.

The invention pertains to the use of glucan encapsulated non-immunostimulatory small interfering RNAs (siRNAs) to treat type-2 diabetes. Endocannabinoids (EC) are lipid signaling molecules that act on the same cannabinoid receptors that recognize and mediate the effects of endo- and phytocannabanoids. EC receptor CB1R activation is implicated in the development of obesity and its metabolic consequences, including insulin resistance and type 2 diabetes.

This invention relates to synthetic immunoreactive peptides, which are portions of the M proteins of the most prevalent Group A Streptococcus (GAS) serotypes in the United States. These peptides may be useful in development of a flexible, multivalent GAS vaccine. They can be recognized by M type-specific antibodies and are capable of eliciting functional opsonic antibodies. Additionally, the peptides or isolated antibodies raised in response to the peptides may be useful for GAS diagnostics.

This Intranasal Dry Powder Inhaler (DPI), developed with Creare, Inc., allows low-cost delivery of powder vaccines. Nasal delivery has numerous advantages compared to traditional injected vaccines, including: 1) safe, needle-less administration by minimally-trained staff or patient; 2) better protection due to mucosal and cross-protection; and 3) decreased biohazard waste.

Intranasal delivery is a simple, inexpensive and needle-free route for administration of vaccines and therapeutics. This intranasal delivery technology, developed with Creare LLC., includes low-cost, disposable drug cartridges (DDCs) that mate with a durable hand-held device. The rechargeable-battery-powered device transmits ultrasonic energy to the DDC to aerosolize the drug and is capable of performing for eight hours at 120 vaccinations per hour. Potential applications for this platform technology include intranasal vaccination (e.g.

This invention relates to methods of rapidly detecting influenza, including differentiating between type and subtype. Unlike culture and serological tests requiring 5 to 14 days for completion, CDC researchers developed a rapid, accurate assay, which is easily adapted to kit form. This assay also requires less labor input than immunoassays. These methods can be used to quickly identify a broad variety of influenza types and subtypes, including viruses that may be involved in pandemics (such as H5N1, for example).

Progressive multifocal leukoencephalopathy (PML) is a rare, fatal demyelinating disease of the brain caused by the polyomavirus JC (JCV) under immunosuppressive conditions. It is pathologically characterized by progressive damage of white matter of the brain by destroying oligodendrocytes at multiple locations. Clinically, PML symptoms include weakness or paralysis, vision loss, impaired speech, and cognitive deterioration. The prognosis of PML is generally poor. No effective therapy for PML has been established.

This invention relates to rotavirus vaccine compositions and methods of vaccination. Rotaviral infection is the most commonly occurring gastrointestinal illness of children world, affecting both developed and developing economies. Additionally, rotavirus infections can affect livestock (especially calves and piglets), and resulting mortality/morbidity cause major economic losses for farmers and nations each year.

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.
