A Transition Metal‐Free Approach for the Conversion of Real‐Life Cellulose‐Based Biomass into Formate

open access: yesAdvanced Science, EarlyView.
A visible‐light‐mediated method has been developed for the direct conversion of biomass into formate at ambient temperature and atmospheric pressure. This approach achieves the selective generation of hydroxyl radicals, which subsequently transform sugars, cellulose, and hemicellulose into formate.

IRF8 Drives Conventional Type 1 Dendritic Cell Differentiation and CD8+ T Cell Activation to Aggravate Abdominal Aortic Aneurysm Development

open access: yesAdvanced Science, EarlyView.
This study highlights the critical role of IRF8 in the development of AAA. IRF8 activation promotes the differentiation of cDC1s, which in turn recruit and activate CD8+ T cells, contributing to aortic wall degradation. The study identifies the IRF8‐cDC1‐CD8+ T cell axis as a key pathway in AAA progression, offering new potential therapeutic targets to
