A quarter of the world's population is estimated to be infected with Myobacterium tuberculosis (Mtb). Infection is detected by immune response to M. tuberculosis antigens using either tuberculin skin test (TST) and interferon gamma release (IGRA's), tests which have low sensitivity in immunocompromised. IL-7 is an important cytokine for T-cell function with potential to augment cytokine release in in-vitro assays. This study aimed to determine whether the addition of IL-7 in interferon-gamma release assays (IGRAs) improves its diagnostic performance of Mtb infection.

Resistance to latent Mycobacterium tuberculosis (M.tb) infection, identified by persistently negative tuberculin skin tests (TST) and interferon-gamma release assays (IGRA), after close contact with p...
Since the second half of the 20th century the incidence of tuberculosis has been declining in Poland. Despite this, current epidemiological data still support the need for the continued mass BCG vacci...
We previously reported increased unstimulated blood levels of interferon-gamma in persons with latent tuberculosis infection (LTBI) in the United States, suggesting enhanced immune activation in LTBI....
Tuberculosis (TB) in animals is a re-emerging disease with a wide range of hosts that causes large economic losses in livestock. Goats are particularly susceptible to TB and, in endemic areas, vaccina...
New blood tests have become available to detect either latent or active tuberculosis. These tests - which according to the CDC can replace the tuberculin skin test - measure the production...
This study will evaluate the lung's immune response to mycobacterium tuberculosis (Mtb) infection and will modulate that response with interferon-gamma.
The purpose of this research study is to test the safety and effectiveness of inhaled Interferon gamma-1b (IFN-g 1b), when administered for 48 weeks and in combination with oral antibiotic...
To examine the effectiveness of subcutaneous gamma interferon in reducing severity of Mycobacterium avium- intracellulare (MAI) bacillemia episodes in AIDS patients in an open-label dose-r...
When administered simultaneously, interferon-alpha 2b + interferon-gamma result in dramatic antiviral synergy.Ribavirin has shown to enhance interferon-gamma levels in patients with chroni...
The assay of INTERFERON-GAMMA released from lymphocytes after their exposure to a specific test antigen, to check for IMMUNOLOGIC MEMORY resulting from a previous exposure to the antigen. The amount of interferon-gamma released is usually assayed by an ENZYME-LINKED IMMUNOSORBENT ASSAY.
A type II interferon produced by recombinant DNA technology. It is similar to the interferon secreted by lymphocytes and has antiviral and antineoplastic activity.
The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.
An interferon regulatory factor that recruits STAT1 PROTEIN and STAT2 PROTEIN heterodimers to interferon-stimulated response elements and functions as an immediate-early protein.
A multimeric complex that functions as a ligand-dependent transcription factor. ISGF3 is assembled in the CYTOPLASM and translocated to the CELL NUCLEUS in response to INTERFERON signaling. It consists of ISGF3-GAMMA and ISGF3-ALPHA, and it regulates expression of many interferon-responsive GENES.
Immunoassay - ELISA
Immunoassays are quick and accurate tests to detect specific molecules. Immunoassays rely on an antibody to bind to the specific structure of a molecule. Antibodies are proteins generated by animals in response to the invasion of a foreign molecule (anti...
Tuberculosis (TB) is an infectious disease caused by bacteria belonging to the Mycobacterium tuberculosis complex. Over nine million new cases of TB, and nearly two million deaths from TB, are estimated to occur around the world every year, and new inf...
