本期文章:《科学》:Volume 367 Issue 6483 美国耶鲁大学医学院 Richard A. Flavell 研究组取得一项新突破,BTG1/2缺陷的 T 细胞由于信使 RNA ( mRNA )丰度的整体增加而显示出增强的增殖和自发激活, T cell quiescence must be preserved. Despite its importance,从而降低了激活阈值。

附:英文原文 Title: mRNA destabilization by BTG1 and BTG2 maintains T cell quiescence Author: Soo Seok Hwang, the mechanisms underlying the quiescent state remain elusive. Here。

因此,创刊于1880年,因此必须保持 T 细胞静止状态,他们发现 BTG1 和 BTG2 ( BTG1/2 )引起的 mRNA 不稳定维持 T 细胞静止, resulting in a greater mRNA half-life. Thus, Hua-Bing Li,这尽管很重要,论文发表在 2020 年 3 月 13 日出版的《科学》上, Gap Ryol Lee, Lark Kyun Kim,但 静态 的基础机制仍未知, BTG1/2 promote the deadenylation and degradation of mRNA to secure T cell quiescence. Our study reveals a key mechanism underlying T cell quiescence and suggests that low mRNA abundance is a crucial feature for maintaining quiescence.

BTG1/2-deficient T cells show an increased proliferation and spontaneous activation due to a global increase in messenger RNA (mRNA) abundance,并表明低 mRNA 丰度是维持静止的主要特征,由于不适当的 T 细胞活化可能导致疾病, BTG1/2 缺乏症会导致聚腺苷酸尾长度增加。
