Chai et al. (2020) have depicted the effect of curcumin on ALI/ARDS using cecal ligation and puncture (CLP)-induced ALI mouse model. In this study, curcumin noticeably attenuates lung injury by inducing the differentiation of regulatory T cells (Tregs) and upregulating IL-10 production. Similar effects have been observed in the neuropathic model, colitis model, and other inflammatory diseases. Therefore, in the context of inflammation, curcumin can act as a double-edged sword, downregulating pro-inflammatory cytokines, and upregulating anti-inflammatory IL-10 (Chai et al., 2020). Here, IL10 is linked to acute respiratory distress syndrome.
