What is Al 17A?

Interleukin 17A (IL-17A) is one of the currently known six members of the IL-17 cytokine family and is implicated in immune responses to infectious pathogens and in the pathogenesis of inflammatory autoimmune diseases like psoriasis.

What is an IL-17A inhibitor?

Abstract. Secukinumab, ixekizumab and brodalumab are monoclonal antibody therapies that inhibit interleukin (IL)-17 activity and are widely used for the treatment of psoriasis, psoriatic arthritis and ankylosing spondylitis.

What are Th22 cells?

Th22 cells are abundant in human skin and play important roles in epidermal wound healing (15). These cells are tissue homing CD4+T cells and exhibit anti-inflammatory, antibacterial and antiviral activities.

Does Th17 produce IL-23?

Th17 cells expressed increased levels of IL-17, IL-17F, IL-26, and IL-23R. In contrast, IL-22 production was downregulated in the presence of TGF-β (49). In their study, Volpe et al.

Is Humira an IL-17?

MADRID — In patients with psoriatic arthritis, the combined end point of skin clearance and reduced disease activity was better with ixekizumab (Taltz, Eli Lilly), an interleukin (IL)-17 inhibitor, than with adalimumab (Humira, AbbVie), a TNF inhibitor, early results from the SPIRIT-H2H (NCT03151551) trial show.

What is the IL-17 receptor family?

The IL-17 receptor family now consists of 5 members (IL-17RA, RB, RC, RD and RE), all of which, like their ligands, share sequence homology ( Fig. 1 ). IL-17RA is ubiquitously expressed on a wide range of tissues and cell types.

What are the signaling pathways of the IL-17 cytokines?

Of the IL-17 family cytokines, the signaling pathways activated by IL-17A and IL-17E/IL-25 are the most fully characterized. Binding of IL-17A to its receptor complex leads to the recruitment of the ACT1 adaptor protein, which interacts with the IL-17 receptor through their shared SEFIR domains.

What is il-17e/il-25?

IL-17E/IL-25 is the most divergent member of the IL-17 cytokine family and promotes biological effects that are distinct from those induced by other IL-17 family members. IL-17E signals through a receptor complex consisting of IL-17B R/IL-17RB and IL-17RA.

What is the mechanism of action of Il 17F?

IL-17F is able to induce several cytokines, chemokines and adhesion molecules in bronchial epithelial cells, vein endothelial cells, fibroblasts and eosinophils. IL-17F utilizes IL-17RA and IL-17RC as its receptors and activates the MAP kinase-related pathway.
