Interferon gamma (IFNG or IFN-γ) is a dimerized soluble cytokine that is the only member of the type II class of interferons. [5] The existence of this interferon, which early in its history was known as immune interferon, was described by E. F. Wheelock as a product of human leukocytes stimulated with phytohemagglutinin, and by others as a product of antigen-stimulated lymphocytes. [6]
C-X-C motif chemokine ligand 10 (CXCL10) also known as Interferon gamma-induced protein 10 (IP-10) or small-inducible cytokine B10 is an 8.7 kDa protein that in humans is encoded by the CXCL10 gene. [ 5 ] [ 6 ] C-X-C motif chemokine 10 is a small cytokine belonging to the CXC chemokine family.
The human interferon-gamma receptor complex consists the heterodimer of two chains: IFNGR1 and IFNGR2. [2] [3] In unstimulated cells, these subunits are not preassociated with each other but rather associate through their intracellular domains with inactive forms of specific Janus family kinases (Jak1 and Jak2). Jak1 and Jak2 constitutively ...
Interferon gamma (IFN-gamma) also significantly stimulates the MHC II-dependent presentation of antigens. Higher MHC I expression increases presentation of viral and abnormal peptides from cancer cells to cytotoxic T cells , while the immunoproteasome processes these peptides for loading onto the MHC I molecule, thereby increasing the ...
T-SPOT.TB counts the number of antimycobacterial effector T cells, white blood cells that produce interferon-gamma, in a sample of blood.This gives an overall measurement of the host immune response against mycobacteria, which can reveal the presence of infection with Mycobacterium tuberculosis, the causative agent of tuberculosis (TB).
The vaccinia virus interferon (IFN)-gamma receptor (IFN-gammaR), which is a 43 kDa soluble glycoprotein that is secreted from infected cells early during infection. IFN-gammaR from vaccinia virus, cowpox virus and camelpox virus exist naturally as homodimers , whereas the cellular IFN-gammaR dimerises only upon binding the homodimeric IFN-gamma.
Interferon-γ (IFN-γ) release assays rely on the fact that T-lymphocytes will release IFN-γ when exposed to specific antigens. These tests are mostly developed for the field of tuberculosis diagnosis , but in theory, may be used in the diagnosis of other diseases that rely on cell-mediated immunity, e.g. cytomegalovirus and leishmaniasis and ...
Gamma-interferon-inducible protein Ifi-16 (Ifi-16) also known as interferon-inducible myeloid differentiation transcriptional activator is a protein that in humans is encoded by the IFI16 gene. [ 5 ] [ 6 ] [ 7 ]
