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.

Targeted Gene Mutation Technology for Studying Specific Cell Functions in Mice

This technology includes the development of transgenic mice with a targeted gene mutation that flanks exon 8 of the Ikzf2 (Helios) gene using loxP sites. These Ikzf2 fl/fl (floxed) mice allow researchers to selectively delete the Ikzf2 gene in specific tissues or cells by crossing them with mice that express Cre recombinase under tissue-specific promoters.

Immunotherapy for Treating HER2-Positive Breast Cancer

This technology includes a novel immunotherapy approach designed to target HER2-positive breast cancer cells. It leverages a specific mechanism to enhance the immune system's ability to identify and destroy these cancer cells. The technology demonstrated significant potential in pre-clinical in vivo studies, suggesting it could improve treatment outcomes for patients with HER2-positive breast cancer

Enhanced Stability and Efficacy of Pfs48/45 Domain III Protein Variants for Malaria Vaccine Development Using SPEEDesign Technology

The technology includes modifying the Plasmodium falciparum Pfs48/45 Domain III protein sequence to enhance its stability and efficacy to aid in malaria vaccine development. This approach successfully overcomes previous production challenges by increasing the thermostability of the antigen and eliminating the need for additional modifications that could impair vaccine effectiveness. Crucially, the technology maintains the essential neutralizing epitope of Pfs48/45, ensuring its effectiveness in preventing malaria transmission as a transmission-blocking vaccine.

Nanobodies Neutralizing Lassa Virus

Lassa Hemorrhagic Fever (LHF) is a serious disease caused by infection with Lassa virus (LASV) – highly prevalent in West Africa and spreading globally. LASV is associated with high morbidity and mortality rates, annually infecting 100,000 to 300,000 individuals and causing 5,000 deaths. Developing prophylactics and treatment for LASV is difficult due to challenges in inducing neutralizing antibodies and producing their target, the LASV glycoprotein trimer (GPC).

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.

Human Monoclonal Antibodies That Target the RH5 Complex of Blood-Stage Plasmodium Falciparum

249 million people were afflicted with malaria in 2022. There are five Plasmodium parasite species that cause malaria in humans. Of the five, Plasmodium falciparum causes most of the incidence of human disease. Most advanced malaria vaccine candidates can confer only partial, short-term protection in malaria-endemic areas. The pathogenesis of malaria is associated with blood-stage infection and antibodies specific to the parasite blood-stage antigens may be able to control parasitemia.

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.

 

Human Monoclonal Antibodies That Target Plasmodium Falciparum Sporozoites

Malaria is one of the worlds deadliest infectious diseases, causing an estimated 249 million cases and 608,000 deaths annually, with children in the regions of Africa and South Asia being most vulnerable. Approx 2,000 cases of malaria are reported in the United States each year, by travelers from malaria-risk countries. Malaria is a mosquito-borne parasitic disease transmitted through the bite of infected female mosquitoes, which introduces Plasmodium sporozoites into the bloodstream of the human host.

Novel System for HIV-1 Vaccine Development

The available technologies describe specific immunogenic peptides, peptide modifications and methods for identifying additional immunogens against HIV-1 surface proteins, gp120 and gp41. Additionally, detailed methods for use of the described immunogenic peptides in the development of vaccines and diagnostics for HIV-1 are disclosed. The current technologies further include a comprehensive system for immunogen design, comprising in silico design coupled to feedback from X-ray crystallography, antigenic analysis, and immunization.
