Construction of Recombinant Baculoviruses Carrying the Gene Encoding the Major Capsid Protein, VP1, From Calicivirus Strains (Including Norovirus Strains Toronto, Hawaii, Desert Shield, Snow Mountain, and MD145-12)

The noroviruses (known as "Norwalk-like viruses") are associated with an estimated 23,000,000 cases of acute gastroenteritis in the United States each year. Norovirus illness often occurs in outbreaks, affecting large numbers of individuals, illustrated recently by well-publicized reports of gastroenteritis outbreaks on several recreational cruise ships and in settings such as hospitals and schools. Norovirus disease is clearly important in terms of medical costs and missed workdays, and accumulating data support its emerging recognition as important agents of diarrhea-related morbidity.

Soluble Antigen-Based ELISA for the Detection of B. malayi Infections

The technology presented is a breakthrough in the diagnosis of lymphatic filariasis, specifically targeting the B. malayi pathogen. It encompasses a novel soluble antigen extract used in both IgG and IgG4-based ELISA tests, aimed at detecting the presence of the filarial infection. This innovation serves as a cornerstone for a CLIA-certified reference test, established and utilized in Dr. Nutman's laboratory since the late 1980s.

Diagnostic Assays and Methods of Use for Detection of Filarial Infection

The effort targeting the mosquito borne neglected tropical disease lymphatic filariasis for elimination through mass drug administration by 2020 will require accurate, cost effective methods for detecting early infections. The World Health Organization-recommended immunochromatographic test detects adult Wuchereria bancrofti (Wb) antigen in blood, but shows variable efficacy due to the complex life cycle of the parasites and cross reactivity with other organisms. This variability may hinder effective lymphatic filariasis elimination efforts.

Antibodies and Methods for the Diagnosis and Treatment of Epstein-Barr Virus Infection

According to the World Health Organization, over 90% of the worldwide population is infected with Epstein-Barr virus by adulthood. In most cases, the disease accompanying initial infection is subclinical though some individuals who are infected as adolescents or adults do experience infectious mononucleosis. However, once infected, individuals carry latent EBV for their remaining lifespan. In such individuals, immune suppression can result in reactivation of the EBV and consequently, EBV-associated lymphoproliferative disease.

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).

A Key Advancement for Human Norovirus Research and Reverse Genetics

The HEK293T/T7 cell line is a novel development in virology research, particularly for studying human noroviruses. This cell line expresses the T7 RNA polymerase, a key enzyme used in reverse genetics systems. Unlike existing technologies, the HEK293T/T7 cell line offers the unique advantage of being able to produce functional T7 RNA polymerase, which is essential for driving transcription from T7 promoters.

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 S10-3 Cell Line for Advanced Hepatitis E Virus Research and Therapeutic Development

The Huh-7 cell line underwent a detailed sub-cloning process to enhance its effectiveness for Hepatitis E Virus (HEV) infection studies. This involved diluting and culturing cells in 96-well plates until confluent monolayers formed, followed by selection and expansion of the most suitable cells. The sub-clone S10-3, derived from this process, was identified as the most efficient for transfection and infection by HEV.

Simple, Quantitative Sensitive High-throughput Antibody Detection for Lyme Disease

This technology is for compositions and methods for diagnosis of Lyme disease. Currently, Lyme disease is diagnosed by clinical exam and a history of exposure to endemic regions. Although, laboratory tests may aid diagnosis, the best tests currently available are slow and labor intensive and require understanding of the test, and infection stage. A two-step antibody based test process is currently the recommended laboratory test. The first step is either an enzyme immunoassay (EIA), or an indirect immunofluorescence assay (IFA).
