Background

Interleukin-13 (IL-13) is a pleiotropic type 2 cytokine discovered in 1993 as a product of activated T helper 2 (Th2) cells, crucial for orchestrating allergic inflammation and immune responses. Signals through a heterodimeric receptor complex comprising IL-13Rα1 and IL-4Rα (type II IL-4 receptor). IL-13 binds IL-13Rα1 with moderate affinity (KD = 30 nM), recruiting IL-4Rα to activate downstream pathways. Activation of JAK1 and JAK2/TYK2 tyrosine kinases, leading to STAT6 phosphorylation, dimerization, and nuclear translocation to regulate gene transcription.

Great production
Color: Cream White
It’s very comfy and doesn’t take too much space like those gaming chairs which I like a lot. I also like the back of the chair is not all the way up but it’s supporting the waist and the back very well. Easy to assemble and very pretty ivory faux leather and wood combination.

Backrest does not adjust in and out
Color: Black
Very comfortable but I wish the back rest was adjustable. It’s too far back to offer any support.

Very good chair, comfortable and high quality.
Color: Black
I had my doubts, yet after a couple months I really love this chair. Its a very good quality. Comfortable and sturdy. It allows for me to lean back too, which is a big plus! It looks really great and I am glad I purchased this chair. If you are looking, then just buy it because it is as good as it looks in the pictures.
