Real-time in vivo Imaging of LPS-induced Local Inflammation and Drug Deposition in NF-κB Reporter Mice

[Abstract]  Wound, biomaterial, and surgical infections are all characterized by a localized and excessive inflammation, motivating the development of in vivo methods focused on the analysis of local immune events. However, current inflammation models, such as the commonly used in vivo models of endotoxin-induced inflammation are based on systemic, usually intraperitoneal, administration of lipopolysaccharide (LPS), causing endotoxin shock. Here, we describe a model of LPS-induced local inflammation in NF-κB-RE-Luc reporter mice. LPS, alone or with added therapeutic substances, is ... [摘要]  [摘要 ] 伤口,生物材料和外科手术感染均以局部和过度炎症为特征,从而推动了专注于分析局部免疫事件的体内方法的发展。然而,当前的炎症模型,例如内毒素诱导的炎症的常用体内模型,是基于系统性的,通常是腹膜内注射脂多糖(LPS),引起内毒素休克。在这里,我们描述了LPS诱导局部炎症的模型NF- κ 乙-RE-Luc报告小鼠。LPS单独或与其他治疗物质一起通过水凝胶局部递送, 沉积皮下,提供一个空间限定的环境中,使得能够在体内生物成像本地NF-的分析κ 乙活化。可以在同一只小鼠中纵向分析药物功效的评估,并且使用荧光标记的药物,可以同时分析局部药物沉积,并将其与炎症部位相关联。最后,该方案还可以用于研究药物从局部沉积的凝胶和其他生物材料的保留和系统释放。

[背景 ] 局部过度的TLR应答的原因,有时不相称的炎症,如在不同类型的伤口和生物材料感染的观察。这些伤口并发症延迟了正常的愈合,并增加了严重感染和败血症的风险。考虑到后者,已经开发了败血症和内毒素休克的几种实验模型,其研究了系统性炎症的发展(Lewis 等,2016)。然而,需要从机械学和治疗学角度解决局部炎症事件的模型。甲转录ctivation 因子NF- κ 乙是各种炎性病症的关键组成部分,因此,NF- κ 乙被认为是重要的治疗靶标(刘等人,2017) 。实时的,纵向体内NF-的成像κ 乙活化NF κ ...

House Dust Mite Extract and Cytokine Instillation of Mouse Airways and Subsequent Cellular Analysis

[Abstract]  Asthma is a complex disease of the airways primarily mediated by T helper 2 cells and innate lymphoid type 2 cells (Licona et al.,2013). Mice do not develop spontaneous asthma and therefore models have been developed for the assessment of key processes that underlie human pathology (Nial et al.,2008). Exposure to House Dust Mite (HDM) extract induces many key features of acute airway inflammation including elevated IgE levels, eosinophilia, goblet cell metaplasia, epithelial hypertrophy and airway hyperresponsiveness (AHR) in response to methacholine (Hammad et al., ... [摘要]  哮喘是主要由T辅助细胞2和先天淋巴2型细胞介导的气道的复杂疾病(Licona等人,2013)。小鼠不发展自发性哮喘,因此已经开发了用于评估作为人类病理学基础的关键过程的模型(Nial等人,2008)。暴露于房尘螨(HDM)提取物诱导急性气道炎症的许多关键特征,包括升高的IgE水平,嗜酸性粒细胞增多,杯状细胞化生,上皮肥大和响应乙酰甲胆碱的气道高反应性(AHR)(Hammad等人, ,2009; Dullaers等人,2012; Coquet等人,2015)。暴露于HDM的确切剂量和持续时间可以影响炎症的类型和程度。在我们的情况下,我们从在攻击时增加的低致敏剂量开始,而其他的在小鼠致敏期间使用不同的方案或更高的抗原浓度(Hondowicz等人,2016; Trompette < et="" al="" 。,2014; ="" zaiss="" et="" al="" 。,2015)。我们认为使用低敏感剂量更准确地分离初级和次级免疫应答,并降低致敏过程中给予的hdm继续刺激攻击期间的免疫应答的可能性(coquet等人,2015;="" plantinga="" et="" al="" 。,2013)。在这里,我们在文本,图片和视频中概述了如何通过鼻内途径施用hdm提取物或细胞因子,并简要地谈谈随后在气道中的炎症的分析[在han&="">
