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).

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.

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.

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

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.

Toxoplasma gondii is the zoonotic causative agent of toxoplasmosis, a disease of significant concern for pregnant persons and livestock. A member of the phylum Apicomplexa, Toxoplasma gondii can infect almost any cell type found in mammals and birds. There are multiple transmission pathways, including consumption of undercooked meat from infected animals, consumption of unwashed plants, contaminated water supplies, blood transfers, and congenital transfer. Felines are considered the definitive host of Toxoplasma gondii.

The pork tapeworm, Taenia solium, is endemic in most of Asia, Latin America, and Sub-Saharan Africa. The risk of infection is increased in regions where pigs are raised in closed proximity to humans, with migration from endemic regions being directly proportional to the prevalence of infection in high-income countries. Human infection by T. solium occurs following oral ingestion of eggs passed in human feces from an infected carrier. The larvae can travel anywhere in the human body.
