Development and Characterization of the SLC46A3 Knockout Mouse Line

Summary:

The NCI is seeking licensees for the SLC46A3 knockout mouse line.

Description of Technology:

Nonalcoholic fatty liver disease is caused by several factors including 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), an environmental contaminant. TCDD causes lipid accumulation in humans by inducing the Solute Carrier Family 46 Member 3 (SLC46A3) gene expression. To effectively study TCDD-mediated lipid accumulation, research tools such as SLC46A3 knockout cells and animal models are required.

qPCR Assay for Detection of JC Virus

JC Virus causes a fatal disease in the brain called progressive multifocal leukoencephalopathy (PML) that occurs in many patients with immunocompromised conditions. For example, more than five percent (5%) of AIDS patients develop PML. Additionally, these conditions include, but are not limited to, cancers such as leukemias and lymphomas, organ transplants such as kidney, heart and autoimmune conditions with treatment that modulates the immune system such as Multiple Sclerosis (MS), rheumatoid arthritis, psoriasis, and systemic lupus erythematosus.

A Novel Strategy to Produce 6-cys Proteins Based on Pfs230D1 Domain Fusions

The Plasmodium parasite has a complex lifecycle during human infection and in the mosquito vector. Most advanced malaria vaccine candidates can confer only partial, short-term protection in malaria-endemic areas. A means of breaking the transmission of malaria to subsequent individuals could prevent a significant amount of human disease.

The primary embodiments of this technology are novel compositions of matter that produce enhanced transmission-blocking responses over current transmission blocking vaccines:

SARS-CoV-2 Virus Specimen and Material Sharing

The Centers for Disease Control and Prevention (CDC) and the National Institute for Allergy and Infectious Diseases (NIAID) have been rewarded for their partnership from the 2021 Federal Laboratory Consortium (FLC) awards. The CDC and NIAID had already developed a new approach to sharing samples during a Public Health Emergency of International Concern (PHEIC) during the Zika pandemic, which enabled them to respond quickly and efficiently to access and share samples of SARS-CoV-2 early in the outbreak.

Rapid Sharing of SARS-CoV-2 Prefusion Stabilized Spike Proteins and Plasmids

Within hours of the public release of the viral genome sequence, scientists at the Vaccine Research Center (VRC) of the National Institute of Allergy and Infectious Diseases (NIAID) and their collaborators engineered a key protein from SARS-CoV-2, the virus that causes COVID-19, to enable its study as a vaccine candidate and for research applications.

Mast Cell Line for Research on Allergies and Inflammatory Diseases

Reactive mast cells are the culprit in allergic diseases and have also been implicated in other diseases ranging from autoimmune disorders to cancer to atherosclerosis. These immune sentinel cells normally defend against parasites and bacteria, but sometimes they overreact to harmless intruders, such as pollens or plant oils, releasing granules loaded with inflammation-inciting molecules, such as histamine, as well as various proteases and cytokines that cause allergic and inflammatory reactions. 

Innovative Techniques and Reagents for Improved Genetic Engineering

The development of restriction enzyme technology in the 1970s was a breakthrough in molecular biology research. For the first time, scientists were able to cut DNA at specific sites, and insert sequences with matching ends. However, the technology was limited to insertion at particular sites in the host vector, and the size of the inserted DNA quickly became a limiting factor.
