[Abstract]  CD4+ T cell responses have been shown to be protective in many respiratory virus infections. In the respiratory tract, CD4+ T cells include cells in the airway and parenchyma and cells adhering to the pulmonary vasculature. Here we discuss in detail the methods that are useful for characterizing CD4+ T cells in different anatomic locations in mouse lungs. [摘要]  许多呼吸道病毒感染中CD4细胞反应已被证明是保护性的。在呼吸道中,CD4 + T细胞包括气道中的细胞和附着于肺血管的细胞和细胞。在这里,我们详细讨论了可用于表征小鼠肺不同解剖位置的CD4 + T细胞的方法。

背景 为了区分循环和组织中的记忆T细胞,已经开发了一种T细胞血管内染色的方法(Anderson等人,2012)。这种方法被广泛用于定义许多器官和组织(包括肺,脾和肠)的记忆T细胞。然而,呼吸道中的记忆T细胞位于三个独特的解剖位置,即气道,薄壁组织和肺血管。血管内染色不能区分气道和实质中的细胞,因为它们都是从循环中分离的,血管内施用的抗体不会污染这两个群体。我们设计了同时进行的鼻内/血管内抗体标记测定,可以使用最少量的抗体来标记和区分所有三个位置的细胞。

[Abstract]  Therapy-induced hypoxia drives changes in the tumor microenvironment that contribute to the poor response to therapy. Hypoxia is capable of driving the expression and/or activation of specific signaling cascades (e.g., c-Met, Axl, CTGF), the recruitment of tumor promoting immune cells, and the induction of cell survival pathways including autophagy (Phan et al., 2013; Hu et al., 2012; Ye et al., 2010). We have recently shown that anti-VEGF therapy-induced hypoxia can result in changes in the extracellular matrix that contribute to the aggressiveness of tumors post therapy (Aguilera et al., 2014). Importantly, therapies that induce hypoxia do not always increase epithelial plasticity and tumor aggressiveness (Ostapoff et al., 2013; ... [摘要]  治疗诱导的缺氧驱动肿瘤微环境中的变化,其导致对治疗的差的反应。缺氧能够驱动特异性信号级联(例如,c-Met,Axl,CTGF)的表达和/或活化,肿瘤促进免疫细胞的募集和细胞存活途径的诱导,包括自噬(Phan等人,2013; Hu等人,2012; Ye等人,2010)。我们最近已经显示,抗VEGF治疗诱导的缺氧可以导致细胞外基质的变化,其有助于治疗后肿瘤的侵袭性(Aguilera等人,2014)。重要的是,诱导缺氧的治疗不总是增加上皮可塑性和肿瘤侵袭性(Ostapoff等人,2013; Cenik等人,2013)。我们已经使用哌莫硝唑来评价肿瘤中的缺氧,并且在本文中为这种有用的工具提供详细的方案来询问体内缺氧水平。
Hypoxyprobe TM (哌莫硝唑盐酸盐)免疫组织化学分析方法的实用性允许评估不同组织以及细胞类型中的缺氧。哌莫硝唑是2-硝基咪唑,其在缺氧细胞中特异性地被还原活化,并与蛋白质,肽和氨基酸中的巯基形成稳定的加合物(Cenik等人,2013; Arnold等人。,2010; Raleigh和Koch,1990; Raleigh等人,1998)。此外,检测到的吡莫硝唑的量与肿瘤内的缺氧水平成正比
