Exosome‐Like Nanoparticles From Lactobacillus rhamnosusGG Protect Against Alcohol‐Associated Liver Disease Through Intestinal Aryl Hydrocarbon Receptor in Mice

Zelin Gu, Fengyuan Li, Yunhuan Liu, Mengwei Jiang, Lihua Zhang, Liqing He, Daniel W. Wilkey, Michael Merchant, Xiang Zhang, Zhong‐Bin Deng, Shao‐Yu Chen, Shirish Barve, Craig J. McClain, Wenke Feng – 4 February 2021 – Alcohol‐associated liver disease (ALD) is a major cause of mortality. Gut barrier dysfunction–induced bacterial translocation and endotoxin release contribute to the pathogenesis of ALD. Probiotic Lactobacillus rhamnosus GG (LGG) is known to be beneficial on experimental ALD by reinforcing the intestinal barrier function.

Natural Killer Cells Regulate the Maturation of Liver Sinusoidal Endothelial Cells Thereby Promoting Intrahepatic T‐Cell Responses in a Mouse Model

Yanqin Du, Hu Yan, Shi Zou, Tanvi Khera, Jia Li, Meihong Han, Xiaoli Yang, Baoju Wang, Jia Liu, Shuilin Sun, Xin Zheng, Ulf Dittmer, Mengji Lu, Dongliang Yang, Heiner Wedemeyer, Jun Wu – 4 February 2021 – Functional maturation of liver sinusoidal endothelial cells (LSECs) plays an important role in intrahepatic T‐cell activation and control of viral infections. Natural killer (NK) cells have been reported to prompt the maturation of antigen‐presenting cells (APCs), especially for dendritic cells (DCs), but the interaction between NK cells and LSECs is elusive.
