SARS-CoV-2 Pseudotyping Plasmids for Cutting-Edge Studies
NIAID scientists have developed plasmids that allow for production of pseudoviruses expressing SARS-CoV-2 spike protein. As SARS-CoV-2 is a lethal airborne virus, it must be handled in high-containment Biosafety Level 3 (BSL-3) laboratories that require strict airflow, ventilation and decontamination procedures.
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.
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.
Stable Cell Line Technology for Enhanced Production of Varicella-Zoster Virus Vaccines
This technology includes a stable cell line engineered to have reduced expression of the pro-apoptotic protein Bim when exposed to doxycycline. This reduction in Bim expression allows for significantly higher yields of the Varicella-Zoster Virus (VZV), which is used in the production of live, attenuated VZV vaccines. The enhanced viral production makes this cell line particularly useful for vaccine manufacturing.

Methods for Producing Stem Cell-Like Memory T Cells for Use in T Cell-Based Immunotherapies
T cells currently employed for T cell-based immunotherapies are often senescent, terminally differentiated cells with poor proliferative and survival capacity. Recently, however, scientists at the National Cancer Institute (NCI) identified and characterized a new human memory T cell population with stem cell-like properties. Since these T cells have limited quantities in vivo, the scientists have developed methods by which high numbers of these cells can be generated ex vivo for use in T cell-based immunotherapies.
