这篇讲什么
本文揭示了小鼠肝脏再生过程中,位于中间小叶区的DPP4阳性肝细胞通过机械敏感离子通道PIEZO1感知组织张力,并激活IGFBP2驱动的增殖程序,从而协调肝脏的区带性再生。
原文开头
Ying Zhang, Yuzhuo Sun, Guangkui Xu, Yue Wu, Zhijun Shi, Zhuo Chang, Junjun Liu, Kaidan Pang, Siyu Liu, Han Wang, Weixin Rong, Zehua Shao, Xingqian Liu, Yu He, Yang Yan, Bin Zhou*, Zuyi Yuan*, Xu- Feng Zhang*, Stefan Offermanns*, Shengpeng Wang* INTRODUCTION: The liver can rapidly restore its mass after injury through zone- specific hepatocyte proliferation. However, the underlying mechanisms and whether physical forces are involved in the spatially patterned regenerative response remain unclear. RATIONALE: Although metabolic zonation across the liver lobule is well established, the determinants that mark mid- lobular hepato- cytes for regenerative expansion have yet to be identified. After injury, the remnant liver responds with immediate hepatocyte hypertrophy and increased tissue tension. …
