Myosin-Based Protein-Protein Interaction Assay

Investigators at the National Institute on Deafness and Other Communication Disorders (NIDCD) have developed an assay for the detection of protein-protein interactions in living cells. This assay uses readily-available reagents and straightforward techniques that avoid the difficulty of purifying proteins or generating antibodies required for other binding studies. Proof-of-concept for this assay has been demonstrated, and a manuscript is in preparation for publication.

A VSV-EBOV-Based Vaccine Against COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of for coronavirus disease 2019 (COVID-19). COVID-19 is characterized by fever, cough, difficulty breathing, loss of taste and smell, nausea, and sore throat. As of the fourth quarter 2020, COVID-19 is responsible for over 1.17 million deaths worldwide. As the pandemic continues to surge, the importance of a safe, affordable, and efficacious vaccine is of urgent importance.

Astrocyte Differentiation of Neural Stem Cells with StemPro Embryonic Stem Cell Serum Free Medium for Research and Potential Therapeutic Use

This technology includes an innovative method for differentiating astrocytes from neural stem cells (NSCs). The process involves using Life Technologies StemPro embryonic stem cell serum-free medium to initially guide NSCs towards a neuronal lineage. Over a period of 28-35 days, as the cells are continually passaged, neurons gradually die off, leading to the proliferation of astrocytes. By the end of this differentiation protocol, approximately 70% of the cells exhibit markers characteristic of mature astrocytes, specifically GFAP.

Construction of Recombinant Baculoviruses Carrying the Gene Encoding the Major Capsid Protein, VP1, From Calicivirus Strains (Including Norovirus Strains Toronto, Hawaii, Desert Shield, Snow Mountain, and MD145-12)

The noroviruses (known as "Norwalk-like viruses") are associated with an estimated 23,000,000 cases of acute gastroenteritis in the United States each year. Norovirus illness often occurs in outbreaks, affecting large numbers of individuals, illustrated recently by well-publicized reports of gastroenteritis outbreaks on several recreational cruise ships and in settings such as hospitals and schools. Norovirus disease is clearly important in terms of medical costs and missed workdays, and accumulating data support its emerging recognition as important agents of diarrhea-related morbidity.

Devices for Improved Tissue Cryopreservation and Recovery

Problem: Cryopreservation is a process where living biological materials like cells, tissues, and cell therapies (which are susceptible to damage caused by unregulated chemical kinetics) are preserved by cooling to very low temperatures in the presence of specific cryopreservation media that protects the biological material from damage. In order to be used, the biological material ideally should be thawed in a controlled manner that minimizes damage and desirably brings the material back to a viable state.

A Neural Stem Line from a Niemann Pick C (NPC) Type 1 Patient for Therapy Development

This technology includes a neural stem cell (NSC) line derived from a Niemann Pick C (NPC) patient, aimed at advancing research and drug development for NPC, an inherited neurodegenerative disorder characterized by the accumulation of cholesterol in neurons. The NSCs, which serve as a crucial intermediate cell type, can be differentiated into any neuronal or glial cell of the brain or spinal cord under appropriate culture conditions. These cells originate from fibroblasts reprogrammed into induced pluripotent stem cells.

Neural Stem Cells from an iPSC Line Ubiquitously Expressing Green Fluorescent Protein for Basic Science Research and Cell Line Tracking

This technology involves neural stem cells (NSCs) derived from pluripotent stem cells (PSCs) that can differentiate into neurons and glia. The key feature of this technology is the CY2 EEF1A1 GFP iPSC line, which includes a green fluorescent protein (GFP) expressed under the EEF1A1 promoter, leading to its ubiquitous expression in cells. This characteristic makes the NSCs and the neural cells differentiated from this line exhibit green fluorescence. Such cells, when transplanted into animal models like mice and rats, can be easily tracked due to their fluorescence.
