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.

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.

 

Transgenic Mouse Models for Studying HLA-B57:01 and HLA-B15:02 Linked Immune Responses and Hypersensitivity Reactions

Transgenic mouse models expressing human HLA-B57:01 and HLA-B15:02 molecules have emerged as invaluable tools for unraveling the intricacies of immune responses and hypersensitivity reactions. The major histocompatibility complex (MHC) encoded proteins play a pivotal role in the immune system by presenting peptide fragments to T lymphocytes, and HLA-B57:01 has been associated with severe hypersensitivity reactions triggered by abacavir, a widely used anti-retroviral drug.

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.

Replicative-Defective Mutant Human Cytomegalovirus: Potential Applications in Vaccinology and Cancer Immunotherapy

The potential applications of a replicative-defective mutant form of human cytomegalovirus (HCMV) are significant in the fields of vaccinology and cancer immunotherapy. This innovative approach involves engineering a mutant HCMV that can selectively target specific cells. Firstly, it holds promise as a vaccine candidate for protecting against HCMV infection, given the success of a similar strategy against herpes simplex virus in animal models.

Development of a High-Throughput Screening Tool for RSV Inhibition Using Engineered RSV Expressing GFP and Luciferase Genes

The technology involves the genetic engineering of Respiratory Syncytial Virus (RSV) to express two additional genes, green fluorescent protein (GFP) and Renilla luciferase, from different positions within the viral genome. GFP serves as a visual marker for RSV infection, allowing researchers to monitor and track infected cells using fluorescence microscopy, while luciferase functions as a highly sensitive reporter gene that enables quantitative assessment of viral replication through enzymatic assays.
