Interferons (IFNs, / ˌ ɪ n t ər ˈ f ɪər ɒ n / IN-tər-FEER-on [1]) are a group of signaling proteins [2] made and released by host cells in response to the presence of several viruses. In a typical scenario, a virus-infected cell will release interferons causing nearby cells to heighten their anti-viral defenses.
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]
Cellular immunity protects the body through: T-cell mediated immunity or T-cell immunity: activating antigen-specific cytotoxic T cells that are able to induce apoptosis in body cells displaying epitopes of foreign antigen on their surface, such as virus-infected cells, cells with intracellular bacteria, and cancer cells displaying tumor antigens;
Interleukin 6 (IL6), also referred to as B-cell stimulatory factor-2 (BSF-2) and interferon beta-2, is a cytokine involved in a wide variety of biological functions. [20] It plays an essential role in the final differentiation of B cells into immunoglobulin-secreting cells, as well as inducing myeloma/plasmacytoma growth, nerve cell ...
[22] Estrogen has been shown to promote healing by decrease the production of various proinflammatory cytokines like IL-6, [ 23 ] TNF-α, [ 24 ] and macrophage migration inhibitory factor ( MIF ). Increased MIF levels are often found at the site of chronic non-healing ulcers, with those levels dropping significantly with successful healing.
