性别作为一个生物学变量在肺血管研究中的重要性。
性别差异影响着整个人类健康的疾病易感性、进展和治疗反应,但它们在生物医学研究中的系统整合仍然不平衡。在临床前研究中,经常只使用一种性别的动物,原代细胞的性别通常没有报告或记录不一致,实验很少被用于检测性别特异性的影响。这些限制在肺动脉高压(PAH)中尤其重要,PAH是一种以明显的两性异形为特征的疾病。多环芳烃对女性的影响更大,而男性的右心室功能和存活率更差,这可能涉及由性染色体、激素、遗传和表观遗传调控驱动的复杂生物学机制。基于性别的报告和分析中持续存在的差距继续阻碍着机制的洞察、可重复性和转化的进展。这一观点呼吁在肺血管研究中进行系统的转变,以严格整合性别作为一个生物学变量(SABV)。我们综合了新出现的证据,证明肺血管重构、右心室适应性、细胞外基质组成和细胞对机械和激素信号的反应存在性别依赖性差异。我们强调未报告的细胞、动物和生物试剂(如含激素的血清)的性别如何引入隐藏的偏见和限制可重复性。生物材料、遗传信息动物模型和激素感知实验系统的进步现在为从机制上研究SABV提供了新的机会。最后,我们提出了一个实用的框架来提高透明度,包括标准化的基于性别的元数据,性别分类数据共享,以及感知SABV的分析和计算方法。认识到性别是一个基本的生物学变量,将提高严谨性,加速发现,支持开发更精确、更有效的肺血管疾病治疗方法。

期刊介绍: The American Journal of Physiology-Lung Cellular and Molecular Physiology publishes original research covering the broad scope of molecular, cellular, and integrative aspects of normal and abnormal function of cells and components of the respiratory system. Areas of interest include conducting airways, pulmonary circulation, lung endothelial and epithelial cells, the pleura, neuroendocrine and immunologic cells in the lung, neural cells involved in control of breathing, and cells of the diaphragm and thoracic muscles. The processes to be covered in the Journal include gas-exchange, metabolic control at the cellular level, intracellular signaling, gene expression, genomics, macromolecules and their turnover, cell-cell and cell-matrix interactions, cell motility, secretory mechanisms, membrane function, surfactant, matrix components, mucus and lining materials, lung defenses, macrophage function, transport of salt, water and protein, development and differentiation of the respiratory system, and response to the environment.
