使用EasySep™小鼠CD4+ T细胞分选试剂盒，通过免疫磁珠负选，可轻松高效地从脾细胞或其他组织的单细胞悬液中分选高纯度的小鼠CD4+ T细胞。EasySep™技术结合单克隆抗体的特异性和无柱磁分选系统的简便性，已在发表的研究中广泛应用超过20年。

在该EasySep™负选流程中，非目的细胞通过抗体复合物与磁珠标记。表达以下特异性标志物的非目的细胞将被靶向去除：CD11b、CD45R、Ter119、CD8a、CD49b、CD19、CD11c、TCRγδ和CD24。使用EasySep™磁极吸附后，通过简单地将目的细胞倾倒或吸取至一个新的试管中，即可将被磁珠标记的细胞与不带标记的目的细胞分离开来。在短至15分钟的磁珠分选后，目的CD4+ T细胞可立即用于流式细胞术、细胞培养、基于细胞的实验等下游应用。

An intestinal commensal symbiosis factor controls neuroinflammation via TLR2-mediated CD39 signalling Wang Y et al. Nature Communications 2014

Abstract

The mammalian immune system constitutively senses vast quantities of commensal bacteria and their products through pattern recognition receptors,yet excessive immune reactivity is prevented under homeostasis. The intestinal microbiome can influence host susceptibility to extra-intestinal autoimmune disorders. Here we report that polysaccharide A (PSA),a symbiosis factor for the human intestinal commensal Bacteroides fragilis,protects against central nervous system demyelination and inflammation during experimental autoimmune encephalomyelitis (EAE),an animal model for multiple sclerosis,through Toll-like receptor 2 (TLR2). TLR2 mediates tissue-specific expansion of a critical regulatory CD39(+) CD4 T-cell subset by PSA. Ablation of CD39 signalling abrogates PSA control of EAE manifestations and inflammatory cytokine responses. Further,CD39 confers immune-regulatory phenotypes to total CD4 T cells and Foxp3(+) CD4 Tregs. Importantly,CD39-deficient CD4 T cells show an enhanced capability to drive EAE progression. Our results demonstrate the therapeutic potential and underlying mechanism by which an intestinal symbiont product modulates CNS-targeted demyelination.

Cutting Edge: Nonobese Diabetic Mice Deficient in Chromogranin A Are Protected from Autoimmune Diabetes. Baker RL et al. Journal of Immunology 2016 JAN

Abstract

T cells reactive to β cell Ags are critical players in the development of autoimmune type 1 diabetes. Using a panel of diabetogenic CD4 T cell clones derived from the NOD mouse,we recently identified the β cell secretory granule protein,chromogranin A (ChgA),as a new autoantigen in type 1 diabetes. CD4 T cells reactive to ChgA are pathogenic and rapidly transfer diabetes into young NOD recipients. We report in this article that NOD.ChgA(-/-) mice do not develop diabetes and show little evidence of autoimmunity in the pancreatic islets. Using tetramer analysis,we demonstrate that ChgA-reactive T cells are present in these mice but remain naive. In contrast,in NOD.ChgA(+/+) mice,a majority of the ChgA-reactive T cells are Ag experienced. Our results suggest that the presence of ChgA and subsequent activation of ChgA-reactive T cells are essential for the initiation and development of autoimmune diabetes in NOD mice.

T-bet Regulates Natural Regulatory T Cell Afferent Lymphatic Migration and Suppressive Function. Xiong Y et al. Journal of Immunology 2016 MAR

Abstract

T-bet is essential for natural regulatory T cells (nTreg) to regulate Th1 inflammation,but whether T-bet controls other Treg functions after entering the inflammatory site is unknown. In an islet allograft model,T-bet(-/-) nTreg,but not induced Treg,failed to prolong graft survival as effectively as wild-type Treg. T-bet(-/-) nTreg had no functional deficiency in vitro but failed to home from the graft to draining lymph nodes (dLN) as efficiently as wild type. T-bet regulated expression of adhesion- and migration-related molecules,influencing nTreg distribution in tissues,so that T-bet(-/-) nTreg remained in the grafts rather than migrating to lymphatics and dLN. In contrast,both wild-type and T-bet(-/-) CD4(+) conventional T cells and induced Treg migrated normally toward afferent lymphatics. T-bet(-/-) nTreg displayed instability in the graft,failing to suppress Ag-specific CD4(+) T cells and prevent their infiltration into the graft and dLN. Thus,T-bet regulates nTreg migration into afferent lymphatics and dLN and consequently their suppressive stability in vivo.
