Exosomes From Intestinal Epithelial Cells Promote Hepatic Differentiation of Liver Progenitor Cells in Gut‐Liver‐on‐a‐Chip Models

Advanced Science, EarlyView.
The effects of intestinal epithelial cells and their exosomes on the hepatic differentiation of HPCs are explored in a gut‐liver‐on‐a‐chip. Exosomes from intestinal epithelial cells improve liver fibrosis. Moreover, the miR‐371‐373 cluster in the exosomes may mediate this effect by regulating the hepatic differentiation of HPCs.

Upcycling of Waste Fluororubber to Photocurable High‐Performance Vinyl‐Terminated Liquid Fluororubber by Multifield Coupling One‐Pot Stepwise Reactions

Advanced Science, EarlyView.
Herein, waste fluororubbers undergo controlled oxidative degradation induced by alkali and hydrogen peroxide to yield carboxyl terminated liquid fluororubbers. Subsequently, condensation reaction system efficiently converts carboxyl groups into photoreactive vinyl groups.

Post‐Translational Modified Neoantigens in Autoimmune Diseases: Challenges of Immune Tolerance

Advanced Science, EarlyView.
Autoimmune diseases have a high incidence and disability rate. The pathogenesis of autoimmune diseases involves the interaction among genetic factors, environmental factors, and immune disorders. The post‐translational modified neoantigens are the key nodal of these three factors. And these post‐translational modified neoantigens, after being presented
