Targeting cGAS-STING pathway for reprogramming tumor-associated macrophages to enhance anti-tumor immunotherapy.

The cyclic GMP-AMP synthase (cGAS)-stimulator interferon genes (STING) signaling pathway plays a crucial role in activating innate and specific immunity in anti-tumor immunotherapy. As the major infiltrating cells in the tumor microenvironment (TME), tumor-associated macrophages (TAMs) could be polarized into either anti-tumor M1 or pro-tumor M2 types based on various stimuli. Accordingly, targeted reprogramming TAMs to restore immune balance shows promise as an effective anti-tumor strategy.

WBP1 regulates mitochondrial function and ferroptosis to modulate chemoresistance in colorectal cancer.

Chemoresistance continues to pose a significant challenge in managing colorectal cancer (CRC), resulting in unfavorable outcomes for patients. Recent findings indicate that ferroptosis, an innovative type of regulated cell death, might influence chemoresistance. In this research, we explored how WW domain-binding protein 1 (WBP1) affects mitochondrial function, cell growth, ferroptosis, and chemoresistance in CRC cells.

Neutrophil-modulated Dicer expression in macrophages influences inflammation resolution.

The precise molecular mechanisms through which neutrophils regulate macrophages in the progression and resolution of acute inflammation remain poorly understood. Here, we present new findings on the role of Dicer in regulating macrophage phenotypic transitions essential for proper inflammatory progression and resolution, influenced by neutrophils. Using a zymosan A (Zym A)-induced self-limited mouse peritonitis model, we observed that Dicer expression in macrophages was significantly reduced by neutrophil-derived IFN-γ during the progression phase, but gradually returned to normal levels during the resolution phase following the engulfment of apoptotic neutrophils.
