Prevention or Treatment of Viral Infections by Inhibition of the Histone Methyltransferases EZH1/2

Herpes simplex viral infections, including herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), are exceptionally common worldwide. These viruses establish lifelong persistent infections with cycles of lytic reactivation to produce recurrent diseases including oral and genital lesions, herpetic keratitis/blindness, congenital-developmental syndromes, and viral encephalitis. Infection with HSV-2 increases the rate of human immunodeficiency virus (HIV) transmission in coinfected individuals. DNA replication inhibitors are typically used to treat herpesvirus infections.

FRugally Optimized DNA Octamer (FRODO): DNA Vector and Uses Thereof For Detecting HIV and SIV

Quantitative polymerase chain reactions (qPCRs) are commonly employed to enumerate genes of interest among particular biological samples. Insertion of PCR amplicons into plasmid DNA is a mainstay for creation of known quantities of target sequences to standardize quantitative PCRs. Typically, one amplicon is inserted into one plasmid construct, the plasmid is then amplified, purified, serially diluted, and then quantified to be used to enumerate target sequences in unknown samples.

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.

Anti-Puromycin Antibodies Illuminate the World of Cellular Protein Translation

The Ribopuromycylation (RPM) technology, developed by Dr. Jon Yewdell and Dr. Alexandre David, offers a powerful and universal method for visualizing and studying protein translation within cells. RPM involves the use of puromycin, a molecule that mimics a tyrosyl-tRNA and terminates translation by becoming covalently incorporated into the nascent protein chain's C-terminus within the ribosome's A site. This technique enables the immobilization of puromycylated nascent protein chains on ribosomes when chain elongation inhibitors like cycloheximide or emetine are utilized.

Hybridoma Cell Lines 2A4 And 5B12 Against Puromycin

Protein translation is a central cellular function attracting increasing attention from cell biologists as they integrate gene product specific information into a systems view of cellular function. Scientists at NIAID developed the puromycin-specific antibodies that allow for the specific detection of puromycin-containing nascent polypeptides via standard immunofluorescence or flow cytometry.

Francisella Lipids as Broad Anti-inflammatory Therapeutics

Anti-inflammatory treatments, particularly those used in the context of viral infection, have been shown to greatly inhibit the overall immune response, which can result in poor immunity and failure to control or clear the infection. Novel alternatives that can effectively attenuate inflammation without the more serious side effects of steroid medications (e.g., global immune suppression, muscle weakness, etc.) may have substantial use across a wide range of disease areas.

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.

Broadly Neutralizing Human Anti-HIV Monoclonal Antibody 10E8 and Related Antibodies Capable of Neutralizing Most HIV-1 Strains

The uses for human anti-HIV monoclonal antibody 10E8 and its variants include passive immunization, therapeutic vaccination, and the development of vaccine immunogens. 10E8 is one of the most potent HIV-neutralizing antibodies isolated and it neutralizes up to 98% of diverse HIV-1 strains. 10E8 is specific to the membrane-proximal external region (MPER) of the HIV envelope protein gp41 and 10E8 is orthogonal to other anti-HIV antibodies. In combination with other antibodies 10E8 may provide an antibody response that neutralizes nearly all strains of HIV-1.
