INF-gamma Release ELISpot Assay

Bio-Protocol, 2012
IFN-γ (Interferon-gamma) is produced mainly by activated T cells and NK cells. Production of IFN-γ (Interferon-gamma) by helper T cells as well as cytotoxic T cells is a hallmark of the TH1-type phenotype, thus, high-level production of IFN-γ (Interferon-

Diagnostic Performance of a Novel CXCL10 mRNA Release Assay for Mycobacterium tuberculosis Infection

Frontiers in Microbiology, 2022
One-fourth of the world’s population has been infected with Mycobacterium tuberculosis (M.tb). Although interferon-gamma release assays (IGRAs) have been shown to be valid methods for identifying M.tb infection and auxiliary methods for diagnosis of ...

Determining Mycobacterium tuberculosis infection among BCG-immunised Ugandan children by T-SPOT.TB and tuberculin skin testing. [PDF]

, 2012
BACKGROUND: Children with latent tuberculosis infection (LTBI) represent a huge reservoir for future disease. We wished to determine Mycobacterium tuberculosis (M.tb) infection prevalence among BCG-immunised five-year-old children in Entebbe, Uganda, but

Hemodialysis acutely altered interferon-gamma release assay test result and immune cell profile

Journal of Microbiology, Immunology and Infection, 2022
Patients receiving hemodialysis (HD) are at risk of TB development. IGRA-positive patients showed significant decrease in quantitative IGRA result with alterations in CD3+CD4+CD45RO+, NK cell, and monocyte subsets immediately upon HD procedure.
