Description : | Interleukin-33 (IL-33) is a proinflammatory cytokine that belongs to the IL-1 family. IL-33 is expressed in a variety of cells, including epithelial and endothelial cells, smooth muscle cells, macrophages and fibroblasts. The primary receptors for IL-33 are ST2 and IL-1 receptor accessory protein (IL-1RAcP), both of which belong to the IL-1 receptor family. IL-33 is localized to the nucleus of resting cells where it binds to chromatin in the H2A-H2B histone complex as a transcriptional suppressor. IL-33 is secreted by cells during injury which induces a T-helper 2 type inflammatory response. Evidence suggests IL-33 plays a role in autoimmune disease. IL-33's interaction with ST2 can drive allergic pathology and IL-33 has been reported to play a role in the development of rheumatoid arthritis and systemic lupus erythematosus. |

Q&As (6)
Ask a questionIt can be used to detect immune cells such as macrophages and dendritic cells.
This protein applied in immunology, drug research, life science and other fields.
Regulates the activity of immune cells by binding to receptors to stimulate the production of inflammatory factors such as interferon and TNF-α.
IL33 can also be used to treat a variety of inflammatory diseases, such as inflammatory bowel disease, psoriasis and so on.
The preparation of IL33 requires first cloning the IL33 gene into the expression vector, and then the expression vector is expressed and purified in the cell culture medium.
Treating asthma with recombinant IL33 takes several weeks to several months to be effective, depending on the severity of the condition and the individual patient.
