A novel fluorinated triazole derivative suppresses macrophage activation and alleviates experimental colitis via a Twist1-dependent pathway.

Hyperactivated macrophages play a key role in the initiation and perpetuation of mucosal inflammation in Crohn's disease (CD). Increasing evidence suggests that the basic helix-loop-helix (bHLH) repressor Twist1 can suppress activation of nuclear factor-κB (NF-κB) and the subsequent production of TNF-α, which are both essential elements of macrophage activation. Thus, developing novel therapeutic strategies to enhance Twist1 expression and to inhibit macrophage activation may be beneficial for CD treatment.

Macrophage migration inhibitory factor promotes osteosarcoma growth and lung metastasis through activating the RAS/MAPK pathway.

Emerging evidence suggests that the tumour microenvironment plays a critical role in osteosarcoma (OS) development. Thus, cytokine immunotherapy could be a novel strategy for OS treatment. In this study, we explored the role of macrophage migration inhibitory factor (MIF), an important cytokine in OS progression, and investigated the anti-tumour effects of targeting MIF in OS.
