摘要

虽然衰老与哮喘病理生理之间存在很强的相关性,但其潜在的机制尚未完全阐明。内质网(ER)已被证明是一个重要的细胞内细胞器,参与许多疾病的发病机制。本研究的目的是研究老龄卵清蛋白(OVA)致敏小鼠肺组织中的内质网应激标志物。将雄性BALB/C小鼠随机分为4组(每组10只):1)对照组,2)OVA致敏组(OVA), 3) d -半乳糖致敏组(D-gal), 4) OVA致敏组(OVA+D-gal)。用支气管肺泡灌洗液(BAL)计数白细胞总数和分化细胞数。通过Real - Time-PCR技术分析肺组织内质网应激标志物(ATF4、ATF6、GRP78、CHOP、XBP1)并进行组织病理学评估。数据显示,与对照组相比,OVA、D-gal和OVA+D-gal组的白细胞总数和差异细胞均显著增加,尤其是OVA+D-gal组。此外,结果显示,与对照组相比,OVA组、D-gal组和OVA+D-gal组内质网应激标志物(ATF4、ATF6、GRP78、CHOP和XBP1)的表达量增加显著高于对照组。有趣的是,在OVA+D-gal组中,CHOP、ATF4和XBP1的表达明显高于其他组。在老年ova致敏小鼠中,研究结果显示肺组织中存在适应性不良的内质网应激反应,其特征是CHOP、ATF4和XBP1表达水平升高。

Altered lung inflammation and expression of endoplasmic reticulum stress markers in male mice aged-asthma model.

Although there is a strong correlation between aging and asthma pathophysiology, the underlying mechanism has not been fully elucidated. The endoplasmic reticulum (ER) has been demonstrated to be a crucial intracellular organelle involved in the pathogenesis of numerous diseases. The aim of the current study was to investigate ER stress markers in the lung tissue of aged ovalbumin (OVA)-sensitized mice. Male BALB/C mice were randomly divided into the following four groups (10 in each): 1) control, 2) OVA-sensitized (OVA), 3) D-galactose-induced aging (D-gal), and 4) OVA-sensitized associated with D-galactose-induced aging (OVA+D-gal). Total WBCs and differential cells were counted using the bronchoalveolar lavage (BAL) fluid. Lung tissue was analyzed for ER stress markers (ATF4, ATF6, GRP78, CHOP, and XBP1) through Real Time-PCR technique as well as histopathological assessment. The data indicated a significant increase in both total WBCs and differential cells within the OVA, D-gal, and OVA+D-gal groups when compared to the control group, particularly evident in the OVA+D-gal group. Also, the results showed that the increased expression of ER stress markers (ATF4, ATF6, GRP78, CHOP, and XBP1) was significantly higher in the OVA, D-gal, and OVA+D-gal groups than in the control group. Interestingly, the increased expression of CHOP, ATF4, and XBP1 was observed in the OVA+D-gal group more than in other groups. In aged OVA-sensitized mice, the findings revealed a maladaptive ER stress response in their lung tissue, characterized by elevated levels of CHOP, ATF4, and XBP1 expression.

期刊介绍: Tissue and Cell is devoted to original research on the organization of cells, subcellular and extracellular components at all levels, including the grouping and interrelations of cells in tissues and organs. The journal encourages submission of ultrastructural studies that provide novel insights into structure, function and physiology of cells and tissues, in health and disease. Bioengineering and stem cells studies focused on the description of morphological and/or histological data are also welcomed. Studies investigating the effect of compounds and/or substances on structure of cells and tissues are generally outside the scope of this journal. For consideration, studies should contain a clear rationale on the use of (a) given substance(s), have a compelling morphological and structural focus and present novel incremental findings from previous literature.
