Secondary human lymphoid tissue immune reactions take place in a highly coordinated environment with compartmentalization representing a fundamental feature of this organization. profiling methodologies are indispensable for the understanding of this compartmentalization. Here, we propose a complementary experimental approach aiming to reveal different aspects of this process. The analysis of human tonsils, using a combination of single cell phenotypic analysis based on flow cytometry and multiplex imaging and mass spectrometry-based methodologies, revealed a compartmentalized organization at the cellular and molecular levels. More specifically, the skewed distribution of highly specialized immune cell subsets and relevant soluble mediators was accompanied by a compartmentalized localization of several lipids across different anatomical areas of the tonsillar tissue. The performance of such combinatorial experimental approaches could lead to the identification of novel interactions and molecular targets for the manipulation of lymphoid organ, particularly the germinal center, immune reactions.
继发性人类淋巴组织免疫反应发生在高度协调的环境中,分区化是该组织的一个基本特征。分析方法对于理解这种分区化是必不可少的。在此,我们提出一种互补的实验方法,旨在揭示这一过程的不同方面。通过结合基于流式细胞术的单细胞表型分析、多重成像以及基于质谱的方法对人类扁桃体进行分析,揭示了细胞和分子水平上的分区化组织。更具体地说,高度专业化免疫细胞亚群和相关可溶性介质的偏态分布伴随着几种脂质在扁桃体组织不同解剖区域的分区化定位。这种组合实验方法的应用可能会导致识别出用于操纵淋巴器官,特别是生发中心免疫反应的新型相互作用和分子靶点。
