Inflammasomes driven inflammation in lung cancer revisited: a short review

Abstract

Lung cancer is the leading cause of cancer-related deaths worldwide. The main risk factor for lung cancer is exposure to chemicals present in cigarettes and atmospheric pollutants, which, among other mechanisms, can increase the risk of cancer by inducing pulmonary inflammation. Among the complex features of inflammatory processes, the role of inflammasomes has attracted increasing attention due to their role in different stages of carcinogenesis. Inflammasomes are intracellular multiprotein complexes that when activated promote the maturation of interleukin-1beta (IL-1β) and IL-18, pro-inflammatory cytokines involved in the promotion, progression, epithelial-mesenchymal transition, metastasis, and resistance to therapy of lung cancer. In this way, this review summarizes the recent findings of inflammasome research in different stages of lung cancer, with a focus on non-small cell lung carcinoma (NSCLC), and highlights these multiprotein complexes as promising targets for cancer therapy.
