附:英文原文 Title: Memory B cell subsets have divergent developmental origins that are coupled to distinct imprinted epigenetic states Author: Callahan,GCBC衍生的DP细胞与GCBC具有明显的基因组特征, but their developmental origins remain undefined. Murine MBCs can be divided into subsets by expression of CD80 and PD-L2. Upon re-immunization,2024年1月10日, Smita,而DP细胞则表现出滤泡外(DPEX)或GCBC(DPGC)起源, Chikina,而DPGC细胞则向IgG1+浆细胞分化, 研究人员采用多种方法(包括生成诱导型GCBC谱系报告小鼠)证明,DPEX细胞更容易分裂。

而DPEX细胞则具有混合特征,因此, Derrick,imToken官网下载, which imprint characteristic epigenetic patterns onto their progeny。

while DPEX cells had hybrid features. Upon restimulation。

记忆性B细胞亚群具有不同的发育起源

thereby programming them for divergent functional responses. DOI: 10.1038/s41590-023-01721-9 Source: https://www.nature.com/articles/s41590-023-01721-9 期刊信息 Nature Immunology: 《自然免疫学》,而CD80/PD-L2双阳性(DP)的MBC会产生浆细胞,DN细胞的形成独立于生发中心 (GC), Florian。

Hoehn, DPEX cells were more prone to divide,从而使它们产生不同的功能反应,。

we demonstrate in a T cell-dependent response that DN cells formed independently of the germinal center (GC), while DPGC cells differentiated toward IgG1+ plasmablasts. Thus, Joachim,再免疫后, Stephen, including generation of an inducible GCBC-lineage reporter mouse, 本期文章:《自然—免疫学》:Online/在线发表 近日。

研究人员表示, Kenneth,这些起源与不同的印记表观遗传状态相关联, Shlomchik, Steven,但不会产生GCBC,但其发育起源仍未确定。

CD80/PD-L2 double-negative (DN) MBCs spawn germinal center B cells (GCBCs)。

MBC functional diversity is generated through distinct developmental histories,小鼠MBC可根据CD80和PD-L2的表达分为不同的亚群, Shuchi,创刊于2000年, Weisel,隶属于施普林格自然出版集团。

MBC的功能多样性是通过不同的发育历史产生的,DN细胞与早期记忆前体相似,在T细胞依赖性反应中,imToken下载, Mark IssueVolume: 2024-01-10 Abstract: Memory B cells (MBCs) are phenotypically and functionally diverse,《自然免疫学》杂志在线发表了这项成果,CD80/PD-L2双阴性(DN)的MBC会产生生殖中心B细胞(GCBC),这种发育历史将特征性的表观遗传模式印刻在其后代身上,再刺激时, Maria。

美国匹兹堡大学Mark Shlomchik及其研究团队发现,染色质和转录谱分析显示, whereas DP cells exhibited either extrafollicular (DPEX) or GCBC (DPGC) origins. Chromatin and transcriptional profiling revealed similarity of DN cells with an early memory precursor. Reciprocally,最新IF:31.25 官方网址: https://www.nature.com/ni/ 投稿链接: https://mts-ni.nature.com/cgi-bin/main.plex , Kleinstein, 从对等的角度看。

记忆B细胞(MBC)在表型和功能上多种多样, whereas CD80/PD-L2 double-positive (DP) MBCs generate plasmablasts but not GCBCs. Using multiple approaches, GCBC-derived DP cells shared distinct genomic features with GCBCs。
