What are the canonical receptors for IL-6?
The molecular mechanism of IL6 signaling is mediated by IL6 receptor α (IL6-Rα) through the signaling protein IL6ST (also known as gp130). Canonical IL6 signaling involves binding of IL6 to an IL6-Rα/IL6ST complex at the plasma membrane (5).
What is the function of IL-6?
Interleukin 6 (IL-6), promptly and transiently produced in response to infections and tissue injuries, contributes to host defense through the stimulation of acute phase responses, hematopoiesis, and immune reactions.
What is an interleukin-6 IL-6 receptor antagonist?
Interleukin (IL)-6 is a pleiotropic, proinflammatory cytokine produced by a variety of cell types, including lymphocytes, monocytes, and fibroblasts. Infection by SARS-CoV induces a dose-dependent production of IL-6 from bronchial epithelial cells.
What does IL-6 stimulate?
IL-6 is responsible for stimulating acute phase protein synthesis, as well as the production of neutrophils in the bone marrow. It supports the growth of B cells and is antagonistic to regulatory T cells.
Where are IL-6 receptors?
“The human interleukin-6 receptor alpha chain gene is localized on chromosome 1 band q21”.
Is IL-6 proinflammatory and anti inflammatory?
In models of chronic inflammatory diseases, such as collagen-induced arthritis, murine colitis, or experimental autoimmune encephalomyelitis, IL-6 is proinflammatory [28, 29], whereas in models of acute inflammation IL-6 exhibits an anti-inflammatory profile [10].
What drugs are interleukin-6 inhibitors?
Four pharmacologic inhibitors (sometimes termed blockers) of IL-6 are commercially available for clinical use: tocilizumab, sarilumab, and satralizumab, which are all monoclonal antibodies directed against the IL-6 receptor (IL-6R), and siltuximab, a monoclonal antibody specific for IL-6.
Where is interleukin-6 produced?
Interleukin (IL)-6 is produced at the site of inflammation and plays a key role in the acute phase response as defined by a variety of clinical and biological features such as the production of acute phase proteins.
Is IL-6 inflammatory or anti-inflammatory?
What is normal range of IL-6?
Results: The reported values for IL-6 in the blood of healthy donors varied between 0 and 43.5 pg/ml.
What happens if there’s an excessive production of interleukin-6?
IL-6 is implicated in a host of chronic disease conditions associated with inflammation. Interleukin-6 is also suspected to cause increased susceptibility to diabetes mellitus, as well as to the systemic form of juvenile rheumatoid arthritis.
Does TNF induce IL-6?
TNF-α induces IL-6 expression through the p65 phosphorylation at Ser 276, but not at Ser 529 or Ser 536 in murine fibroblasts [5].
