胸腺是T淋巴细胞发育的主要部位,在那里淋巴细胞祖细胞和胸腺基质细胞之间的相互诱导信号引导祖细胞沿着一个特征明确的分化程序进行分化。尽管包括胸腺上皮细胞(TECs)在内的胸腺基质细胞对T细胞介导的免疫的发育至关重要,但它们基础生物学的许多方面一直难以阐明,因为它们在胸腺细胞中所占比例很小,而且它们的分离需要酶消化,这会引起广泛的生理变化。这些障碍与细胞功能的代谢调节研究尤其相关,因为分离过程必然会破坏代谢稳态。与免疫应答过程中T细胞功能的代谢和细胞内信号传导之间已明确的关系相反,胸腺基质细胞功能的代谢调节是一个新兴的研究领域。在此,我们综述了三个不同但相互关联的领域的最新进展:mTOR信号传导的调节、活性氧(ROS)以及自噬,涉及它们在胸腺基质微环境的建立和维持中的作用。
The thymus is the primary site of T lymphocyte development, where mutually inductive signaling between lymphoid progenitors and thymic stromal cells directs the progenitors along a well-characterized program of differentiation. Although thymic stromal cells, including thymic epithelial cells (TECs) are critical for the development of T cell-mediated immunity, many aspects of their basic biology have been difficult to resolve because they represent a small fraction of thymus cellularity, and because their isolation requires enzymatic digestion that induces broad physiological changes. These obstacles are especially relevant to the study of metabolic regulation of cell function, since isolation procedures necessarily disrupt metabolic homeostasis. In contrast to the well-characterized relationships between metabolism and intracellular signaling in T cell function during an immune response, metabolic regulation of thymic stromal cell function represents an emerging area of study. Here, we review recent advances in three distinct, but interconnected areas: regulation of mTOR signaling, reactive oxygen species (ROS), and autophagy, with respect to their roles in the establishment and maintenance of the thymic stromal microenvironment.
