What is the function of IL-17 in the innate immune response?

What is the function of IL-17 in the innate immune response?

Interleukin-17 (IL-17, also known as IL-17A) is a key cytokine that links T cell activation to neutrophil mobilization and activation. As such, IL-17 can mediate protective innate immunity to pathogens or contribute to the pathogenesis of inflammatory diseases, such as psoriasis and rheumatoid arthritis.

What is the role of IL-17?

Interleukin-17 (IL-17) induces the production of granulocyte colony-stimulating factor (G-CSF) and chemokines such as CXCL1 and CXCL2 and is a cytokine that acts as an inflammation mediator.

How do I lower my Th17?

The anti-inflammatory properties of flavonoids are increasingly elucidated in vitro and in animal models of arthritis, as flavonoids have been shown to inhibit cyclooxygenase, to reduce the production of inflammatory cytokines, to suppress p38 MAPK, to inhibit Th17 cells, and to increase Tregs.

Is IL-17 a proinflammatory cytokine?

IL-17 (IL-17A, IL-17F) is a proinflammatory cytokine, essential for host defense against bacteria and fungi. However its importance in autoimmune disease pathogenesis has recently been uncovered, both in patients and in animal models. IL-17 is produced by a subset of activated CD4 T cells under inflammatory conditions.

What does Interleukin 18 indicate?

Interleukin-18 (IL-18) is a potent proinflammatory cytokine that has been reported to be associated with multiple components of metabolic syndrome and to predict the development of type 2 diabetes (7,8).

How do I balance my Th1 dominance?

If Th1 is dominant, he will use Th2 stimulating compounds to raise the level of Th2, and vice versa….Th1 Stimulating Compounds:

  1. Astragalus.
  2. Echinacea.
  3. Medicinal Mushrooms (Maitake and Beta-Glucan are common)
  4. Glycyrrhiza (found in licorice)
  5. Melissa Oficinalis (Lemon balm)
  6. Panax Ginseng.
  7. Chlorella.
  8. Grape Seed Extract.

What is Th1 dominant?

Th1 and Th2 cells are known to antagonize each other in a variety of ways [18, 19], and several chronic inflammatory autoimmune diseases such as multiple sclerosis (MS), diabetes and rheumatoid arthritis (RA) have been described as Th1 dominant diseases [20], while atopy and allergy are Th2 dominant diseases [21].

Is Interleukin 2 anti-inflammatory?

Recent studies, including those coming from our groups, show that several major pro- inflammatory cytokines and chemokines, including IFN-, IL-2, CCL2, and CXCL12, may also function as anti-inflammatory mediators and therefore, may have potential as anti-inflammatory drugs.

Is IL-2 pro or anti-inflammatory?

IL-10 is the most important anti-inflammatory cytokine found within the human immune response. It is a potent inhibitor of Th1 cytokines, including both IL-2 and IFN- g. This activity accounts for its initial designation as cytokine synthesis inhibition factor.

Is IL-18 pro or anti inflammatory?

Interleukin-18 (IL-18) IL-18 is a pro-inflammatory cytokine that was first characterized in the mid-1990s and originally named interferon-γ (IFN-γ) inducing factor [92].

What is the half life of IL-6?

It really looks like it is a difficult question to find the answer for. From what I understand from the links you suggested, it seems as the half-life of IL-6 is somewhere between 2 and 6h. The 15h suggestion is based on an in vivo response and there is probably a sustained production of this cytokine.

Can a naive T cell produce IL-22?

The prototypical IFN-γ producing Th1 cells can produce IL-22 without additional growth factors during effector function. However, naive T cells require the presence of transforming growth factor-β (TGF-β) to drive either the formation of Th17 cells, which can then produce IL-22, and/or T regulatory cells (Tregs; Littman and Rudensky, 2010 ).

Where is IL-22 expressed in the human body?

IL-22 is expressed by inflammatory cells in a number of tissues in the body including the lungs, liver, kidneys, thymus, pancreas, breast, gut, skin, and synovium, reviewed in Dudakov et al. (2015). The focus of this review article is on the distinct roles of IL-22 within the intestine.

When was Interleukin 22 discovered in the intestine?

Interleukin (IL)-22 is a member of the IL-10 family of cytokines that has been extensively studied since its discovery in 2000. This review article aims to describe the cellular sources and signaling pathways of this cytokine as well as the functions of IL-22 in the intestine.
