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.

Recombinant Sulfated HIV Envelope Protein and Methods for Making Protein

This technology comprises sulfated recombinant gp120 proteins and peptides. Also included are methods for producing sulfated recombinant gp120 proteins. The focus of this technology is on sulfation of two tyrosines in the V2 loop of the HIV major envelope glycoprotein, gp120, which increase the stability of gp120 and promote the synthesis of gp120 protein in its native "closed" conformation. Gp120 in its native form is highly sulfated; however, recombinant gp120 produced for vaccines or structural analyses typically display low levels of V2 tyrosine sulfation.

Dual-Germline Antibody Engager Chimeric HIV–1 Immunogens

Despite four decades of intensive research, a safe and effective HIV-1 vaccine remains elusive due to the extreme difficulty in eliciting broadly neutralizing antibodies (bNAbs), which recognize and block HIV-1 from entering healthy cells. Only rare natural HIV-1 envelopes (Envs) promote the activation and expansion of naive B cells expressing unmutated germline antibodies of various bNAb lineages, but they typically do so for a single lineage for the same neutralization site.

Epstein-Barr Virus (EBV)-feeder Cell Line

This technology includes irradiated Epstein-Barr virus-transformed lymphoblastoid cell lines (EBV-LCL) as feeder cells for the ex vivo expansion of natural killer (NK) cells. EBV-LCL feeder cells, altered by radiation to prevent uncontrolled growth, provide a supportive environment for NK cells to multiply effectively. This method addresses the challenge of obtaining sufficient quantities of functionally active NK cells, which are crucial components of the immune system known for their ability to target and destroy tumor cells and virally infected cells.

Synthetic Bacterial Nanoparticles as Drug and Vaccine Delivery Vehicles

Bacterial spores can be modified to display molecules of interest, including drugs, immunogenic peptides, antibodies and other functional proteins of interest (such as enzymes).  The resulting engineered bacterial spores can provide many useful functions such as the treatment of infections, use as an adjuvant for the delivery of vaccines, and the enzymatic degradation of environmental pollutants.

Human Monoclonal Antibodies that Broadly Target Coronaviruses

An abstract for this invention was published in the Federal Register on June 10, 2022. The family of coronaviruses cause upper respiratory tract disease in humans and have caused three major disease outbreaks in recent history: the 2003 SARS outbreak, the 2012 MERS outbreak, and the current SARS-CoV-2 pandemic. There is an urgent need for strategies that broadly target coronaviruses, both to deal with new SARS-CoV-2 variants and future coronavirus outbreaks.

TACSTD2 in HCV Infection and Hepatocellular Carcinoma: Transcriptomics Insights

This technology involves studying the role of the Tumor-Associated Calcium Signal Transducer 2 (TACSTD2) gene in Hepatitis C Virus (HCV) infection and hepatocellular carcinoma. Researchers perform transcriptomics analysis on liver specimens from HCV-infected patients, identify TACSTD2 as a key gene, and create a stable cell line that overexpresses TACSTD2 to investigate its impact on HCV infection and replication. This technology aims to provide insights into the molecular mechanisms of HCV infection and its association with liver cancer.
