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.

A Robust Network Sodium Carboxymethyl Cellulose-Epichlorohydrin Binder for Silicon Anodes in Lithium-Ion Batteries.

Silicon (Si), as an ideal anode component for lithium-ion batteries, is susceptible to substantial volume changes, leading to pulverization and excessive electrolyte consumption, ultimately resulting in a rapid decline in the cycle stability. Herein, a new sodium carboxymethyl cellulose-epichlorohydrin (CMC-ECH) binder featuring a three-dimensional (3D) network cross-linked structure is synthesized by a simple ring-opening reaction, which can effectively bond the Si anode through abundant covalent and hydrogen bonds to mitigate its pulverization. Benefitting from the merits of the CMC-ECH binder, the electrochemical performance is significantly enhanced compared to the CMC binder.
