Abstract

Neutrophil extracellular traps (NETs) are DNA networks released by neutrophils, first described as a defense response against pathogens but have since been associated with numerous inflammatory diseases. Diverse physical material properties have been shown to promote NET formation. Herein, we report the discovery that the charge of self-assembled peptide hydrogels predictably modulates the formation of NETs in vivo within the implanted material. Positively charged gels induce rapid NET release, whereas negatively charged gels do not. This differential immune response to our self-assembled peptide gels enabled the development of a material platform that allows rheostat-like modulation over the degree of NET formation with anatomical and locoregional control.

利用不同电荷的自组装水凝胶调节中性粒细胞胞外陷阱在体内的局部精确形成。
中性粒细胞胞外陷阱(NETs)是由中性粒细胞释放的DNA网络,最初被描述为对病原体的防御反应,但后来与许多炎症性疾病有关。不同的物理材料性质已被证明可以促进NET的形成。在此,我们报告发现自组装肽水凝胶的电荷可预测地调节植入材料体内NETs的形成。带正电荷的凝胶诱导快速NET释放,而带负电荷的凝胶则不会。这种对我们的自组装肽凝胶的差异免疫反应使材料平台的开发成为可能,该平台允许通过解剖和局部区域控制对NET形成程度进行变阻器样调节。

期刊介绍: ACS Central Science publishes significant primary reports on research in chemistry and allied fields where chemical approaches are pivotal. As the first fully open-access journal by the American Chemical Society, it covers compelling and important contributions to the broad chemistry and scientific community. "Central science," a term popularized nearly 40 years ago, emphasizes chemistry's central role in connecting physical and life sciences, and fundamental sciences with applied disciplines like medicine and engineering. The journal focuses on exceptional quality articles, addressing advances in fundamental chemistry and interdisciplinary research.
