Efficient mRNA-Based Genetic Engineering of Human NK Cells with High-Affinity CD16 and CCR7

A highly efficient method to genetically modify natural killer (NK) cells to induce expression of high affinity CD16 (HA-CD16) through mRNA electroporation, to potentiate NK cell-mediated antibody-dependent cellular cytotoxicity (ADCC). ADCC is mediated by CD16+ NK cells following adoptive NK cell transfer, but most humans express CD16 which has a relatively low affinity for IgG1 antibodies.

Development of a Transferrable Norwalk Virus Epitope and Detector Monoclonal Antibody

Noroviruses are now recognized as the major cause of non-bacterial gastroenteritis in all age groups, and efforts are underway to develop an effective vaccine. The lack of a robust cell culture system for human noroviruses has complicated vaccine development. Hence, norovirus virus like particles (VLPs) have played an important role in the understanding of virus structure, immune response, antigenic diversity, and vaccine design.

Direct Reading Detection Kits for Surface Contamination by Anti-Neoplastic (Anti-Cancer) Drugs

Anti-neoplastic drugs, also known as anti-cancer drugs or chemotherapy, are used in the treatment of many types of cancer. However, these drugs are harmful to healthy cells as well as the cancerous cells. Exposure of healthcare workers to anti-neoplastic drugs from contaminated surfaces and drug vials in hospitals and pharmacies is a continuing problem as the drugs can cause both acute and long-term effects. Although there are sensitive techniques to evaluate contamination, results from these tests take time and must be performed in a laboratory.

Pyrophosphate Analog HIV-1 Reverse Transcriptase Inhibitors

The invention relates to compounds that inhibit HIV-1 DNA synthesis mediated by reverse transcriptase (RT). HIV-1 DNA synthesis by RT utilizes deoxynucleoside 5’-triphosphate (dNTP) as substrate and like many other enzymes, the reaction is reversible. Pyrophosphate analogs like imidodiphosphate strongly promote reverse reaction dNTP products containing the imidodiphosphate group instead of the naturally occurring pyrophosphate group. This imidodiphosphate-containing dNTP was found to be a potent inhibitor of the forward RT reaction.

Neutralizing Antibodies to Influenza HA and Their Use and Identification

The effectiveness of current influenza vaccines varies by strain and season, in part because influenza viruses continuously evolve to evade human immune responses. While the majority of seasonal influenza infections cause relatively mild symptoms, each year influenza virus infections result in over 500,000 hospitalizations in the United States and Europe. Current standard of care for individuals hospitalized with uncomplicated influenza infection is administration of neuraminidase inhibitors.

Real-Time PCR Assay for Detection of Carbapenem Antibiotic Resistance Genes of the IMP-type

Antibiotic resistance is one of the world's most pressing health concerns. ß-lactamases, such as carbapenemases, are enzymes produced by bacteria that provide resistance to multiple ß-lactam antibiotics (e.g., penicillins, cephamycins, and carbapenems) by breaking down the antibiotic molecules and deactivating their antibacterial properties. Carbapenems are broad-spectrum antibiotics often prescribed to treat serious infections in hospitalized patients, and infections with carbapenem-resistant Enterobacteriaceae (CRE) have become a challenge in healthcare settings.

Real-Time RT-PCR Assay for the Rapid Detection of Rabies and Other Lyssaviruses

Rabies occurs in more than 150 countries and territories, resulting in at least 55,000 human deaths per year worldwide according to World Health Organization estimates. Rabies is a vaccine-preventable viral disease caused by numerous lyssaviruses that are found in a variety of animal species throughout the world. Rabies virus infects the central nervous system, causing disease in the brain with almost 100% mortality once clinical symptoms manifest.

West Nile/Zika Virus Chimeras for Inactivated Zika Vaccine and Diagnostic Assay Development

Zika virus (ZIKV) is a flavivirus primarily transmitted by infected Aedes mosquitoes. Infection with ZIKV during pregnancy can affect the fetus causing microcephaly, neurological complications, and other birth defects. Adults are also at risk of developing Guillain-Barre syndrome and other neurological disorders from ZIKV infection. In response to the 2015-2016 Zika outbreak, CDC researchers developed new Zika virus chimeras that can be used for inactivated Zika vaccine candidates and faster Zika antibody (Ab) neutralization assay testing.

Personalized Cancer Evaluation (PERCEVAL) Method and Software

Cancer represents the leading cause of morbidity and mortality worldwide, with approximately 14 million new cases and 8.2 million cancer related deaths in 2012. This number is predicted to rise by approximately 70% over the next two decades according to the World Health Organization. Prognosis depends heavily on both early detection and frequent monitoring of the patient's response to treatment. Cancerous tumors shed nucleic acids into blood, which can be detected by ultra-deep sequencing of mitochondrial DNA (mtDNA).
