小鼠常规αβ CD4+T细胞各亚群及其表面标记 传统的小鼠TCRαβCD4 + T 细胞可以通过按Time设门、散射光参数和排除粘连细胞/死细胞来圈出活的淋巴细胞,并对 CD3ε + 或 TCRβ + 细胞和 CD4 + CD8α - 细胞进行设门。使用 CD3ε 或 TCR-β 作为选择...
T Cell Development | 8.1 T Cell Development(T细胞发育)T细胞发育主要发生在胸腺(Thymus)1. 造血干细胞的迁移T细胞的前体细胞起源于骨髓中的造血干细胞(HSCs)。这些前体细胞会通过血液迁移到胸腺,在胸腺中开始T细胞的分化和发育。2. 双阴性阶段在胸腺中,前体细胞首先进入“双阴性”阶段(不表达CD4或CD8表面分子)。
2.有一些marker可以表征这种动态变化过程 根据表型,功能及转录因子,目前CD8+T细胞可以进一步分为以下不同的亚群: Tnaive CD44-CD62+ T SCM :干细胞记忆T细胞(Stem cell memory T cell) T EM:效应记忆T细胞(Effector memory T Cell):CD44+CD62L- T CM:中枢记忆T细胞(Central memory T Cell):CD44+CD62L+ T...
Memory T cellExtrathymic T cellAgingTransgenic mouseCD44(high)CD8 T cells in naive mice, which increase with age, and are often referred to as memory CD8 T cells. However, since thymus-independent CD8 T cells have also been shown to be CD44(high), the origin of the CD44(high)CD8 T ...
在小鼠中使用CD44、CD62L和CCR7等标记物来识别初始(Tn)、中央记忆(Tcm)和效应记忆(Tem)/效应(Teff)亚群,以及KLRG1和CD127,用于识别记忆前体效应细胞(MPEC)和短寿命效应细胞(SLEC)亚群。见下图,SPF 3个月大和18个月大的C57BL/6J小鼠的脾细胞,分别分析Tn、...

Infusion of CD8+ memory T cells after transplantation was able to eradicate the BCL1 lymphoma even after progressive growth without inducing severe GVHD. In conclusion, the memory CD8+ T-cell subset separated graft antilymphoma activity from GVHD more effectively than naive T cells, memory CD4+ ...
Non-Hematopoietic Antigen Blocks Early Memory Imprinting Of Graft-Versus-Host Reactive CD8 Cells Donor T cell alloreactivity can be co-opted to deliver a graft-versus-tumor (GVT) response following blood or bone marrow transplantation (BMT). However, the major reason for treatment failure following...
Graft versus host disease (GVHD) is triggered by host antigen-presenting cells (APCs) that activate donor T cells to proliferate and differentiate, but which APC-activated donor T-cell subsets mediate GVHD versus beneficial antitumor effects is not known. Using a CD8+ T cell–dependent mouse mod...
