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]
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 ...
CXCL10 is secreted by several cell types in response to IFN-γ.These cell types include monocytes, endothelial cells and fibroblasts. [5] CXCL10 has been attributed to several roles, such as chemoattraction for monocytes/macrophages, T cells, NK cells, and dendritic cells, promotion of T cell adhesion to endothelial cells, antitumor activity, and inhibition of bone marrow colony formation and ...
They include interleukin-1 (IL-1), IL-6, IL-12, and IL-18, tumor necrosis factor alpha (TNF-α), interferon gamma (IFNγ), and granulocyte-macrophage colony stimulating factor (GM-CSF) and play an important role in mediating the innate immune response. Inflammatory cytokines are predominantly produced by and involved in the upregulation of ...
The interferon-gamma receptor (IFNGR) protein complex is the heterodimer of two chains: IFNGR1 and IFNGR2. It binds interferon-γ , the sole member of interferon type II . Structure and function
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 ...
The T h cells receiving both signals of activation and proliferation will then become T h 0 (T helper 0) cells that secrete IL-2, IL-4 and interferon gamma (IFN-γ). The T h 0 cells will then differentiate into T h 1 or T h 2 cells depending on cytokine environment. IFN-γ drives T h 1 cell production while IL-10 and IL-4 inhibit T h 1 cell ...
In molecular biology, the guanylate-binding proteins family is a family of GTPases that is induced by interferon (IFN)-gamma.GTPases induced by IFN-gamma (Interferon-inducible GTPase) are key to the protective immunity against microbial and viral pathogens.
