Description : Interleukin 9, also known as IL-9, is a cytokine (cell signalling molecule) belonging to the group of interleukins. IL-9 is a cytokine that acts as a regulator of a variety of hematopoietic cells. This cytokine stimulates cell proliferation and prevents apoptosis. It functions through the interleukin 9 receptor (IL-9R), which activates different signal transducer and activator (STAT) proteins and thus connects this cytokine to various biological processes. Genetic studies on a mouse model of asthma demonstrated that this cytokine is a determining factor in the pathogenesis of bronchial hyperresponsiveness. IL-9 is a key molecule that affects differentiation of TH17 cells and Treg function. IL-9 predominantly produced by TH17 cells, synergizes with TGF-β1 to differentiate naïve CD4+ T cells into TH17 cells, while IL-9 secretion by TH17 cells is regulated by IL-23. Interestingly, IL-9 enhances the suppressive functions of FoxP3+ CD4+ Treg cells in vitro, and absence of IL-9 signaling weakens the suppressive activity of nTregs in vivo, leading to an increase in effector cells and worsening of experimental autoimmune encephalomyelitis. The mechanism of IL-9 effects on TH17 and Tregs is through activation of STAT3 and STAT5 signaling. Our findings highlight a role of IL-9 as a regulator of pathogenic versus protective mechanisms of immune responses.

Q&As (6)

Ask a question
How is the clinical trial of IL9 progressing? 09/05/2022

Several clinical trials are currently underway to evaluate the safety and effectiveness of IL9 in treating conditions such as asthma and allergies. However, the research is still in its early stages and more data are needed.

How to obtain IL9? 03/13/2022

IL9 can be synthesized in the laboratory by biotechnological methods. Before clinical use, it needs to go through strict quality control and testing.

What is the action mechanism of IL9? 09/22/2021

By binding to specific receptors, IL9 can activate relevant signaling pathways and regulate the development and function of immune cells. It can affect the activity of a variety of immune cells, such as T cells and macrophages.

Howthe relationship between IL9 and other related cytokines? 05/02/2020

IL9 has cross-action with other cytokines, which can regulate the expression and function of each other. For example, IL9 can promote the production of IL4 and IL13, and IL4 and IL13 can also promote the secretion of IL9.

What are the clinical applications of IL9? 09/26/2019

IL9 can be used to treat certain inflammatory diseases, such as asthma and skin allergies. It can regulate the response of the immune system and reduce the symptoms of related diseases.

What is the mechanism of action of IL9 in the treatment of asthma? 01/11/2019

The mechanism of action of IL9 in asthma treatment is not fully understood, but studies have shown that it can reduce the infiltration of inflammatory cells and the release of inflammatory mediators, thereby reducing the symptoms of asthma.

    Widely used, IL-9 is related to the occurrence of many diseases, such as asthma, esophageal cancer, colon cancer, fatty liver, etc., and has a wide range of research and application prospects. -


      In tumor therapy, IL-9 has immunoenhancement and anti-tumor effects, which can induce tumor cell apoptosis, inhibit tumor cell proliferation, and promote the killing effect of immune cells. -


        Because IL-9 is associated with many immune cells, its therapeutic properties exhibit lower toxic side effects compared to other immunotherapy approaches. -
