又称为记忆性前体细胞(precursors of memory T cells, TMP),具有存活优势,其生存下来,并进一步分化为不同的记忆性T细胞亚类,包括位于淋巴组织的中央记忆细胞(central memory, TCM),在外周血液与组织之间循环的效应记忆细胞(effector memory, TEM)以及定居于外周组织的组织驻留记忆细胞(tissue resident memory...
急性感染中,CD8+初始T细胞在接受抗原刺激之后,可分化为CD8+效应T细胞(effector CD8+ T cells, TEFF)。如果抗原被清除,一部分的TEFF会持续存在,形成长寿的可以自我更新的记忆T细胞(memory CD8+ T cells, TMEM),以对再次感染产生快速的免疫反应。相反,在慢性感染或者肿瘤中,抗原持续存在,初始T细胞的分化将会变得不一...
2022年4月16日,中国科学院生物物理研究所秦志海课题组在《European Journal of Immunology》杂志在线发表了题为"Dysfunctionof S100A4+ effector memory CD8+ T cells aggravates asthma"的文章。该研究揭示:S100A4是导致S100A4+效应记忆型CD8+ T(CD8+TEM)细胞亚群效应功能失活的关键分子;随着过敏性哮喘的不断加重,S...
Therefore, these key transcription factors link the long-term renewal of memory CD8(+) T cells to their characteristic effector potency.doi:10.1038/ni1268Intlekofer, Andrew MTakemoto, NaofumiWherry, E JohnLongworth, Sarah ANorthrup, John T
这项研究的结果于2017年12月13日在线发表在Nature期刊上,论文标题为“Effector CD8 T cells dedifferentiate into long-lived memory cells”。论文通信作者为埃默里疫苗中心主任Rafi Ahmed博士。论文第一作者Ben Youngblood博士如今在美国圣犹大儿童研究医院工作。

effector cells and secondary response of memory cells17,18,19, and is also potentially involved in the stepwise differentiation into memory T cells20,21,22,23(division-linked differentiation). Given the importance of cell cycle progression in immune responses, T-cell proliferation has been analysed...

Naïve CD8+ T cells can differentiate into effector (Teff), memory (Tmem) or exhausted (Tex) T cells. These developmental pathways are associated with distinct transcriptional and epigenetic changes that endow cells with different functional capacities and therefore therapeutic potential. The molecular...
