Dr. Sumiko Kimura, a former professor of biology at Chiba University, was known as a distinguished biochemist who contributed considerably to our knowledge about the cytoskeleton of muscle cells, especially through her work on connectin (also called titin) and actin regulatory proteins. Sadly, she suddenly passed away in Tokyo on November 1, 2018 at the age of 71. She succumbed to multiple organ failure caused by a bacterial infection following a third operation on her heart. Dr. Kimura had been continuing her research into connectin right up until several months before her decease.

木村幸美子博士进行肌肉研究和教育的伟大遗产

千叶大学前生物学教授Sumiko Kimura博士被称为杰出的生物化学家，他为我们对肌肉细胞的细胞骨架的了解做出了巨大贡献，特别是通过她在connectin（也称为titin）和肌动蛋白调节蛋白方面的工作。不幸的是，她突然于2018年11月1日在东京去世，享年71岁。她因心脏第三次手术而死于细菌感染引起的多器官衰竭。木村博士一直在继续研究connectin，直到病逝前的几个月。
