Abstract

Aging is interrelated with changes in red blood cell parameters and functionality. In this article, we focus on red blood cells (RBCs) and provide a review of the known changes associated with the characterization of RBC deformability in aging and related pathologies. The biophysical parameters complement the commonly used biochemical parameters and may contribute to a better understanding of the aging process. The power of the deformability measurement approach is well established in clinical settings. Measuring RBCs' deformability has the advantage of relative simplicity, and it reflects the complex effects developing in erythrocytes during aging. However, aging and related pathological conditions also promote heterogeneity of RBC features and have a certain impact on the variance in erythrocyte cell properties. The possible applications of deformability as an early biophysical biomarker of pathological states are discussed, and modulating PIEZO1 as a therapeutic target is suggested. The changes in RBCs' shape can serve as a proxy for deformability evaluation, leveraging single-cell analysis with imaging flow cytometry and artificial intelligence algorithms. The characterization of biophysical parameters of RBCs is in progress in humans and will provide a better understanding of the complex dynamics of aging.

衰老和相关病症中异质红细胞的变形性。
衰老与红细胞参数和功能的变化息息相关。在本文中,我们将重点关注红细胞(RBC),并对衰老和相关病症中与红细胞变形性特征相关的已知变化进行综述。生物物理参数是对常用生化参数的补充,有助于更好地了解衰老过程。变形性测量方法的威力已在临床环境中得到证实。测量红细胞的变形性具有相对简单的优点,而且能反映红细胞在衰老过程中产生的复杂影响。然而,衰老和相关病理条件也会促进红细胞特征的异质性,并对红细胞特性的差异产生一定影响。本文讨论了将变形性作为病理状态的早期生物物理生物标志物的可能性,并提出了将 PIEZO1 作为治疗靶点的建议。利用成像流式细胞仪和人工智能算法进行单细胞分析,红细胞形状的变化可作为变形性评估的替代指标。目前正在对人类红细胞的生物物理参数进行表征,这将有助于更好地了解衰老的复杂动态。
