澳大利亚研究人员发现与年龄相关的甲状腺细胞类型有助于免疫力减弱. Australian researchers identify age-related thymus cell types contributing to weakened immunity.

来自Walter和Eliza Hall研究所的澳大利亚研究人员发现了两种新的细胞类型,导致作为关键免疫器官的胸腺在人老时丧失功能。 Australian researchers from the Walter and Eliza Hall Institute discovered two new cell types causing the thymus, a key immune organ, to lose function as people age. 胸腺随着年龄变小,以脂肪组织取代T细胞生长区,导致免疫力减弱。 The thymus shrinks with age, replacing T cell growth areas with fatty tissue, resulting in weakened immunity. 科学家们的发现可能会导致新的方法来恢复胸腺的功能，并随着人们的年龄增长保持免疫水平，这可能会使免疫系统较弱的弱势患者受益。 The scientists' findings may lead to new ways to restore the thymus' function and maintain immunity levels as people age, potentially benefiting vulnerable patients with weakened immune systems.
