[Abstract]  The obesity epidemic is the underlying driver of the type 2 diabetes mellitus epidemic. A remarkable accumulation of various pro-inflammatory immune cells in adipose tissues is a hallmark of obesity and leads to pathogenesis of tissue inflammation and insulin resistance. Here, we describe a detailed protocol to isolate adipose tissue stromal vascular cells (SVCs), which enrich various immune cells of adipose tissues. These SVCs can be used to examine the population and activation status of immune cells by tracking their cell surface antigens, gene expression, and activation of specific signaling pathways. [摘要]  肥胖流行是2型糖尿病流行病的根本驱动因素。 脂肪组织中各种促炎免疫细胞的显着积累是肥胖的标志,并导致组织炎症和胰岛素抵抗的发病机制。 在这里,我们描述了分离脂肪组织基质血管细胞(SVCs)的详细方案,其丰富了脂肪组织的各种免疫细胞。 这些SVC可用于通过跟踪其细胞表面抗原,基因表达和特异性信号通路的激活来检查免疫细胞的群体和激活状态。
【背景】过去几十年来,肥胖现在已成为一种流行病,已成为胰岛素抵抗最常见的原因之一。胰岛素抵抗是代谢综合征发病机理的关键病因。代谢综合征的延长状态推动了2型糖尿病(T2DM)的发展(Romeo et al。,2012; Johnson and Olefsky,2013; Saltiel and Olefsky,2017)。
   慢性低度组织炎症伴随着增强的免疫细胞浸润,是啮齿动物和人类肥胖症的标志,并且是通过促进炎症状态和中断胰岛素信号传导来促进胰岛素抵抗的发病机制的主要因素(Romeo等2012年; Johnson和Olefsky,2013; Saltiel和Olefsky,2017)。浸润的免疫细胞如促炎性巨噬细胞和B细胞在调节肥胖相关脂肪组织炎症和胰岛素抵抗中起关键作用(Weisberg等,2003; ...

[Abstract]  To evaluate precisely the relative roles of different splenic phagocytic cells during an immune response, efficient methods for the depletion of specific populations are needed. Here, we describe the protocols for the depletion of splenic dendritic cells (DCs) by human diphtheria toxin (DTx) treatment in target mice (which express the human DTx receptor in all CD11c+ DCs) and for the specific depletion of MARCO+/MOMA-1+ marginal zone macrophages (MZMΦs) with clodronate liposomes (ClLip) treatment (when a small dose of ClLip is ministered, MZMΦs preferentially uptake ClLip, and clodronate is released inside those cells causing apoptosis-mediated cell death). These protocols are adaptations from previous works (Jung et al., 2002; McGaha et al ... [摘要]  为了准确地评估不同的脾吞噬细胞在免疫应答期间的相对作用,需要用于消耗特定群体的有效方法。 在这里,我们描述了通过人类白喉毒素(DTx)治疗在目标小鼠(其在所有CD11c + DC中表达人类DTx受体)中脾脏树突状细胞(DCs) 用氯膦酸脂质体(ClLip)处理(当小剂量的ClLip被分配时,MZMΦs优先摄取)的MARCO + /MOMA-1 + 边缘区巨噬细胞(MZMΦ) ClLip和氯膦酸盐在那些细胞内释放,引起凋亡介导的细胞死亡)。 这些方案是来自先前作品的改编(Jung等人,2002; McGaha等人,2011),并且用于评价DC和MZMΦ的各自的作用 在实验性血液阶段疟疾感染的急性期期间(Borges da Silva等人,2015)。
