近日，eLife发表了中国科学院生物物理研究所朱明昭课题组题为Endothelial SIRPα signaling controls VE-cadherin endocytosis for thymic homing of progenitor cells的研究论文。
鸡免疫系统器官具体工作是什么？养鸡户可能还不清楚免疫器官具体是做什么的，今天来给大家介绍一下！免疫器官分为中枢免疫器官和外周免疫器官。中枢免疫器官是各类免疫细胞发生、分化、发育和成熟的场所。外周免疫器官是淋巴细胞和其他免疫细胞定居、增殖以及产生免疫应答的场所。

Immune clearance of highly pathogenic SIV infection Myeloid cell tropism enables MHC-E–restricted CD8+ T cell priming and vaccine efficacy by the RhCMV/SIV vaccine。
The human thymus is the organ responsible for the maturation of many types of T cells， which are immune cells that protect us from infection. However， it is not well known how these cells develop with a full immune complement that contains the necessary variation to protect us from a variety of pathogens. By performing single-cell RNA sequencing on more than 250，000 cells， Park et al. examined the changes that occur in the thymus over the course of a human life. They found that development occurs in a coordinated manner among immune cells and with their developmental microenvironment. These data allowed for the creation of models of how T cells with different specific immune functions develop in humans.
