Interleukin 33 (IL-33) is a protein that in humans is encoded by the IL33 gene. [5] Interleukin 33 is a member of the IL-1 family that potently drives production of T helper-2 (Th2)-associated cytokines (e.g., IL-4). IL33 is a ligand for ST2 , an IL-1 family receptor that is highly expressed on Th2 cells, mast cells and group 2 innate ...
Interleukin 10 (IL-10) is a protein that inhibits the synthesis of a number of cytokines, including IFN-gamma, IL-2, IL-3, TNF, and GM-CSF produced by activated macrophages and by helper T cells. In structure, IL-10 is a protein of about 160 amino acids that contains four conserved cysteines involved in disulphide bonds. [33]
IL-33 combined with IL-2, IL-7 or TSLP also stimulates cell proliferation. The effector cytokine which is secreted from IL-33- and STAT5 activator-stimulated Th2 cells is IL-13, which is NF-κB dependent. IL-13 is very similar to IL-4 in amino acid sequence and structure. They also used the same type II IL-4 receptor to activate STAT6. [38]
The inflammasome was discovered by the team of Jürg Tschopp, at the University of Lausanne, in 2002. [17] [18] In 2002, it was first reported by Martinon et al. [17] that NLRP1 (NLR family PYD-containing 1) could assemble and oligomerize into a structure in vitro, which activated the caspase-1 cascade, thereby leading to the production of pro-inflammatory cytokines, including IL-1β and IL-18.
Epithelial cells in the lung express the cytokines IL-33 and IL-25, or TSLP, in response to various allergens, fungi, and viruses. These cytokines activate ILC2s, and therefore, an increased number of ILC2s, and type-2 cytokines (IL-4/5/13) are present in patients with allergic asthma. [ 3 ]

Brooke Walker grew up in an Arizona church community. Families, side by side, in communion with God and each other. But the church, she says, was actually a cult. Walker spent her formative years ...
Thermal ellipsoid plots quickly became the de facto standard used in the display of X-ray crystallography data, and are still in wide use today. [6] The first practical use of molecular graphics was a simple display of the protein myoglobin using a wireframe representation in 1966 by Cyrus Levinthal and Robert Langridge working at Project MAC.
