The technology involves genetically engineering Human Metapneumovirus (HMPV) to express enhanced green fluorescent protein (GFP), enabling the monitoring of virus infection and gene expression through GFP fluorescence. This system serves as a sensitive and versatile tool for virology research, antiviral drug screening, and diagnostic applications.
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.
Rotavirus is a major cause of severe diarrhea and dehydration in infants and young children. Vaccines that cover the most important rotavirus serotypes could help reduce serious illness worldwide.
Researchers at NIAID’s Laboratory of Infectious Diseases developed a multivalent human-bovine reassortant rotavirus vaccine using vaccine strains created by combining selected genes from human and bovine (cow) rotaviruses. This approach targets the most important rotavirus serotypes at once, including G1, G2, G3, and G4, with the potential to expand coverage to G5, G9, and G10.
Cancer immunotherapy has transformed treatment for some patients, but many tumors still do not respond well to current options, including checkpoint inhibitors. Researchers at NIAID’s Laboratory of Immune System Biology (LISB) have developed new antibodies designed to help the immune system fight tumors. These lab-made antibodies, called pan-anti-HLA monoclonal antibodies, block signals that can limit immune cell activity.
This technology includes an innovative method for differentiating astrocytes from neural stem cells (NSCs). The process involves using Life Technologies StemPro embryonic stem cell serum-free medium to initially guide NSCs towards a neuronal lineage. Over a period of 28-35 days, as the cells are continually passaged, neurons gradually die off, leading to the proliferation of astrocytes. By the end of this differentiation protocol, approximately 70% of the cells exhibit markers characteristic of mature astrocytes, specifically GFAP.
