Differential Expression of Molecules Associated With Intra-Cerebral Hemorrhage

Description of Technology: Stroke affects 15 million people worldwide each year, and is the number three leading cause of morbidity in the United States. Although most forms of stroke are ischemic in nature, approximately 10-15% of strokes are hemorrhagic. At present, clinical applications for distinguishing between these two forms of stroke do not exist.

The present invention describes a highly predictive, cost-effective diagnostic assay capable of detecting whether an individual has suffered from an intracerebral hemorrhagic stroke and the likelihood of neurological recovery. It comprises a rapid screening device for measuring differential expression patterns of nucleic acid molecules or proteins of at least four hemorrhagic stroke-related genes. Accurate prediction of hemorrhagic stroke will improve rapid diagnosis and aid in determining early treatment regimens.


1. Gene expression profile assay for determining hemorrhagic stroke victims.

2. Means of differentiating between hemorrhagic stroke and ischemic stroke thereby optimizing patient response to stroke therapies.


1. Annually, fifteen billion people suffer from strokes worldwide, and an estimated 700,000 individuals have first-time or recurrent strokes each year in the United States alone.

2. Almost three-fourth of all strokes occur in individuals over 65 years of age.

3. In 2006, the projected indirect and direct costs of stroke are $57.9 billion.

Development Status: This technology requires clinical validation studies.

Diagnosis and Prognosis of Fabry Disease by Detecting Neuronal Apoptosis Inhibitor Protein (NAIP) Expression

Description of Technology: Fabry disease is a severe metabolic disorder that affects the vascular system of multiple tissues and organs. An estimated 1 in 40,000 individuals inherit this rare disease, and suffer from various complications including stroke, renal failure, and cardiac arrest. At present, molecular markers that directly measure cellular dysfunction to not exist, thus, prognosis for Fabry disease therapy can not be assessed.

Available for licensing and commercial development is a rapid diagnostic assay to identify individuals with Fabry disease and an effective mechanism of evaluating enzyme replacement therapy. It provides a quick, inexpensive device for determining expression patterns of the neuronal apoptosis inhibitor protein (NAIP). Peripheral blood white cells of Fabry disease patients are analyzed for elevated levels of the marker NAIP, which is over-expressed in patients suffering from acute strokes. These elevated levels have been found in children with Fabry disease and point to the need for preventive therapies. Additionally, this test can be routinely utilized for evaluation of specific and non-specific therapies that aid in minimizing the complications associated with Fabry disease.


1. Rapid diagnostic test to identify person at risk for Fabry disease.

2. Reliable diagnostic test to identify subject response to Fabry disease therapy.

Market: Individuals genetically susceptible to Fabry disease.

Development Status: This technology requires analytic validation.

Inventors: Raphael Schiffmann (NINDS) et al.

Novel Treatment of Vascular Cognitive Impairment

Description of Technology: Available for licensing are methods and formulations for treating or preventing Vascular Cognitive Impairment (VCI) through mucosal administration of E-selectin, an inducible adhesion molecule on endothelial cells. Vascular dementia is defined as the loss of cognitive function resulting from ischemic, ischemic-hypoxic, or hemorrhagic brain lesions as a result of cerebrovascular diseases and pathologic Start Printed Page 52803changes. Presently no adequate medical treatment exists for VCI.

Cerebrovascular disease causes proinflammatory cytokines such as IL-1 and TNF to induce the expression of E-selectin on human endothelium. E-selectin mediates the adhesion of various leukocytes, including neutrophils, monocytes, eosinophils, natural killer cells, and a subset of T cells to the activated endothelium. Activation of vascular endothelial cells by proinflammatory cytokines is believed to be involved in conversion of the luminal surface of endothelium from anticoagulant and anti-inflammatory to procoagulant and pro-inflammatory. These vascular changes are thought to underlie the development of VCI.

Mucosally administered antigens can inhibit immune responses in an antigen specific fashion by inducing a subset of lymphocytes to produce anti-inflammatory cytokines in the presence of the antigen. This type of tolerance has been termed “bystander suppression”. In an animal model of VCI, intranasal administered E-selectin suppressed activation of vessel segments beginning to express E-selectin and thus prevented the development of VCI. Immunosuppression via antigen-specific modulation of the immune response (mucosal tolerance) should have no systemic immunosuppressive effects.

Use of LCAT To Reduce Cholesterol and Prevent Atherosclerosis

Description of Technology: Available for licensing and commercial development is a method of decreasing accumulation of cholesterol in arteries of humans by administering lecithin-cholesterol acyltransferase (LCAT). This method is useful for the therapeutic treatment of subjects at risk for developing atherosclerosis.

High plasma concentration of HDL cholesterol is associated with reduced risk of cardiovascular diseases (such as ischemic stroke and myocardial infarction). In contrast, low levels of HDL are associated with increased risk of atherosclerotic diseases. The plasma protein enzyme LCAT plays a critical role in the metabolism of HDL and it facilitates the removal of cholesterol from the body. Individuals with a mutation in the LCAT gene have low HDL plasma levels and exhibit an increased risk for atherosclerosis.

Therefore, upregulation of LCAT function has been proposed as an HDL-C increasing therapy, and may have atheroprotective effects. This invention provides for several methods of administering LCAT polypeptide to decrease cholesterol accumulation in arteries.

Development Status: Animal data available.

Devices for Aseptic Lyophilization of Biological Samples

Description of Technology: Biological materials are often lyophilized and stored in small aliquots for long-term preservation as a means of improving stability and expanding shelf life. At present, sterility of solutions cannot be preserved throughout the lyophilization process, and reconstituted samples must be filtered to remove contaminants such as fungi or bacteria, resulting in considerable loss of expensive sample via absorption by the filter. Thus, there exists a need for a device that eliminates microbial contamination throughout the lyophilization process and provides materials that are ready to use following lyophilization.

This technology offers a functional method to prevent microbial contamination during lyophilization and a simple means to prevent contamination. It affords a convenient system for gas venting and exchange utilizing a microcentrifuge tube fitted with a cap incorporating a filter membrane. In a related technology, a unique, cost-effective multi-well plate assembly provides for simultaneous lyophilization of small sample volumes for high-throughput operations. Thus, these technologies are well-suited for researchers concerned about contamination during the lyophilization process. Given the spillage often occurring within centrifugal freeze-dryers, these technologies are also useful even when sterility is not needed, as they prevent contamination from the often-dirty interiors of laboratory centrifugal freeze-dryers, as well as cross-contamination between samples undergoing lyophilization. In addition, by extending shelf-lives, these technologies enable researchers to purchase expensive biomolecules and pharmaceuticals in money-saving bulk quantities. Furthermore, these technologies permit cells to be grown and stored axenically, in small quantities, with or without lyophilization.


1. Maximizes the shelf-lives of expensive biomolecules and pharmaceuticals.

2. Makes practical the bulk purchase of expensive biomolecules and pharmaceuticals by extending shelf-lives.

3. Makes possible the axenic storage of cells via aseptic freeze-drying.

4. Makes possible the production and use of small, sterile aliquots of precious materials by eliminating unnecessary filtration steps.

5. Makes possible the sterile growth of cells in small volumes.


1. Researchers worldwide who utilize sterile, labile compounds.

2. Researchers who utilize microbial, plant, or animal cell cultures.
