Plasmid Useful in Transplantation Therapy for Age-Related Eye Disease

Researchers have developed a green fluorescent protein (GFP) based plasmid that can be used to detect differentiated retinal pigment epithelium (RPE) cells. RPE is a layer of cells located behind the eye that becomes damaged in age-related macular degeneration (AMD). Current cell based therapies for treating AMD focus on generating RPE cells from stem cells. This GPF-based plasmid can be inserted into growing stem cells, and the fluorescence marker can be used to detect and purify stem cells differentiating into RPE cells.

SIRT2 Inhibitors as Novel Therapeutics for Myocardial Infarction and Ischemic Stroke and to Prevent Necrosis

Sirtuin 2 (SIRT2) inhibitors to reduce necrosis and, thereby, as novel therapeutics to treat ischemic stroke and myocardial infarction. Accumulating evidence indicates that programmed necrosis plays a critical role in cell death during ischemia-reperfusion. NIH investigators have shown that the NAD-dependent deacetylase SIRT2 binds constitutively to receptor-interacting protein 3 (RIP3) and that deletion or knockdown of SIRT2 prevents formation of the RIP1-RIP3 complex in mice.

Stapled Peptides for Treatment of Cardiovascular Diseases and Inflammation

The invention is directed to small molecule mimetics of apolipoproteins that have an inter-helical hydrocarbon bond, which stabilizes helix formation.

Apolipoproteins facilitate the transport of lipids and cholesterol in the body. Mimetics of apolipoproteins have been used to treat cholesterol-related disorders. However, these mimetics are susceptible to degradation in biological fluids and as a result, their ability to bind cholesterol becomes diminished over time.

Isolated Lyssavirus Nucleic Acid and Protein Sequences

A novel strain in the rabies family of viruses, the Shimoni bat virus (SHIBV), has been discovered. Phylogenic and antigenic patterns identify SHIBV as a new species of Lyssavirus. Phylogenic reconstructions of SHIBV and monoclonal antibody typing were used to demonstrate a distinct genetic antigenic pattern. This unique genetic information may be used to create antigens or vaccines against SHIBV and provides opportunity for the development of new diagnostics, therapeutics, and prophylactic therapies for viral infection.

Immunogenic Hepatitis E Virus Polypeptides for Vaccine and Diagnostics Development

This technology comprises specific hepatitis E virus (HEV) antigenic polypeptides. HEV causes epidemic and sporadic cases of hepatitis outbreaks with a mortality rate as high as 20% for pregnant women. In order to address this problem, CDC scientists carried out thorough HEV antigen screenings and subsequently developed recombinant proteins that efficiently model major HEV neutralization epitope(s). These recombinant proteins may be considered as candidates for the development of an HEV subunit vaccine, as well as for the development of highly sensitive and specific diagnostic tests.

Real-time PCR Assays for Human Bocavirus Detection and Diagnosis

CDC researchers have developed a real-time PCR assay for the detection and viral-load quantitative estimations of human bocavirus (HBoV) from clinical specimens. At present, there have been few reports on the epidemiology, geographic distribution or clinical features of HBoV infection. Additionally, symptoms affiliated with bocavirus infections overlap with numerous other respiratory illnesses. This CDC assay provides sensitive, specific, and quantitative detection of HBoV in patients with respiratory illness by a method of real-time PCR targeting the HBoV NS1 and NP-1 genes.
