Background:
Interleukin-17A (IL-17A) is a pro-inflammatory cytokine that has gained a lot of attention because of its involvement in respiratory diseases. Interleukin-17 cytokine family includes six members, out of which, IL-17A participates towards the immune responses in allergy and inflammation. It also modulates the progression of respiratory disorders.
Objective:
The present review is an insight into the involvement and contributions of the proinflammatory cytokine IL-17A in chronic respiratory diseases like Idiopathic Pulmonary Fibrosis (IPF), Chronic Obstructive Pulmonary Distress (COPD), asthma, pneumonia, obliterative bronchiolitis, lung cancer and many others.
Conclusion:
IL-17A is a major regulator of inflammatory responses. In all the mentioned diseases, IL- 17A plays a prime role in inducing the diseases, whereas the lack of this pro-inflammatory cytokine reduces the severity of respective respiratory diseases. Thereby, this review suggests IL-17A as an instrumental target in chronic respiratory diseases.
