Generation of Safe-harbor Gene Targeting Donor Plasmids

This technology includes two safe harbor gene targeting donors, specifically designed for applications in the study of induced pluripotent stem cells (iPSC). These include the pAAVS1D-CMV.RFP-EF1a.copGFPpuro and pAAVS1-iCLHN donors. A key feature of these donors is their ability to integrate various transgenes into specific loci through homologous recombination, facilitated by sequences homologous to safe harbor loci. When paired with TALENs targeting these loci, these plasmids enable precise and efficient genome engineering in human cells.

Generation of AAVS1 and C13 “Safe Harbor” Transcription Activator-life Effector Nucleases (TALENs) for Drug Screening or Gene Therapy Development

This technology includes AAVS1 and C13 “safe harbor” transcription activator-life effector nucleases (TALENs) for drug screening or gene therapy applications. TALENs are engineered sequence-specific DNA endonucleases that can significantly enhance genome-editing efficiency by >100-1000 folds. “Safe harbor” such as AAVS1 safe harbor and C13 safe harbor is genome locus that allows robust and persistent transgene expression with no or minimal interference of endogenous gene expression and cell properties.

Monoclonal Antibodies for the Detection of Antiretroviral Integrase Inhibitors

Pre-exposure prophylaxis (PrEP) is a critical component in the fight against HIV but is only effective if persons prescribed PrEP are adhering to the regimens to maintain appropriate drug levels. As PrEP regimens have moved from daily pills to longer lasting injections, the ability to quickly measure and monitor the circulating drug levels of PrEP drugs has increased importance.

Multi Protein Nanoparticle Monkeypox Vaccine

In 2022, the World Health Organization declared an atypical outbreak of monkeypox (Mpox), which has caused approximately 30,000 cases of Mpox infection within the United States as of April 2023. Mpox represents a current threat to public health, and there is an immediate need for an effective vaccine. To address this, NIAID has developed a vaccine approach comprising virus-like nanoparticles coated with modified Mpox proteins.

Novel Methods for Reducing Inflammation and Treating Diseases such as Parkinson's and Alzheimer's Disease

Microglia activation leads to inflammation mediated dopaminergic degeneration in the brain of patients with Parkinson and Alzheimer's Disease. Thus Identification of drugs that reduce microglia activation could prevent or reverse neuronal degeneration in these diseases and other degenerative CNS disorders.

Agonist Epitopes for Renal Cell Carcinoma

Approximately 30,000 patients are diagnosed with renal cell carcinoma (RCC) each year in the United States, and an estimated 12,000 patients die of this disease. Most patients are diagnosed with advanced local disease or metastatic disease. Metastatic RCC carries a poor prognosis with median survivals in the range of 10-12 months. Drugs that inhibit VEGF receptor tyrosine kinases such as Sorafenib and Sunitinib have recently been approved by the FDA to treat metastatic RCC.

High Level Expression and Purification of Untagged and Histidine-tagged Human Immunodeficiency Virus Type-1 Reverse Transcriptase

Human immunodeficiency virus type-1 reverse transcriptase (HIV-1 RT) gene encodes 560 amino acids. In the virus, however, HIV-1 RT occurs as a dimer of two related polypeptides, p66 and p51 subunits at a molar ratio of 1:1. The p51 subunit is derived from a C-terminal proteolytic cleavage of the p66 subunit. This invention describes a simplified protocol to purify large quantities of histidine-tagged and untagged heterodimeric forms of human immunodeficiency virus type-1 reverse transcriptase (HIV-1 RT) from Escherichia coli.

The Use of alpha-4 beta-7 integrin Inhibitors to Inhibit HIV Transmission and Infection

This invention involves the use of inhibitors of alpha-4 beta-7 (a4b7) integrin to inhibit HIV transmission/infection, as a prophylactic to inhibit onset of the acute stage of HIV infection or to treat HIV infection. The a4b7 integrin inhibitors were previously developed for use in other diseases, such as multiple sclerosis or inflammatory bowel disease.
