Abstract

During brain inflammation, rigorous regulation of brain–body communication is required for sufficient, but not excessive, immune activation. As a crucial neuroimmune interface, the choroid plexus (ChP) epithelium serves as both a physical barrier between blood and cerebrospinal fluid (CSF) and a gateway allowing peripheral immune cell entry into the central nervous system (CNS). Recent years have witnessed increasing investigations of ChP events during brain inflammation. Here, we contextualize new findings with established ChP core functions, including CSF secretion and blood–CSF barrier regulation. We reason that the ChP is an organ where immune and nonimmune cells collaborate to defend the CNS. We discuss the pertinent mechanisms and the implications for neurologic disease etiology and treatment. Finally, we discuss outstanding questions for this rapidly expanding field and suggest key technologies and experimental steps to elucidate the full range of ChP functions during neuroinflammatory conditions, such as infection, injury, and aging.

脉络膜丛：炎症期间脑-体交流的指挥中心

在脑炎症期间，需要严格调节脑-体通讯，以充分而不是过度地激活免疫。脉络膜丛（ChP）上皮作为重要的神经免疫界面，既是血液和脑脊液（CSF）之间的物理屏障，也是外周免疫细胞进入中枢神经系统（CNS）的门户。近年来，对脑炎期间ChP事件的研究越来越多。在这里，我们将新发现与已建立的ChP核心功能联系起来，包括CSF分泌和血- CSF屏障调节。我们认为ChP是免疫细胞和非免疫细胞共同保护中枢神经系统的器官。我们讨论了相关的机制和神经系统疾病的病因和治疗的意义。最后，我们讨论了这一快速发展领域的突出问题，并提出了关键技术和实验步骤，以阐明在神经炎症条件下（如感染、损伤和衰老）ChP的全范围功能。

期刊介绍： Current Opinion in Immunology aims to stimulate scientifically grounded, interdisciplinary, multi-scale debate and exchange of ideas. It contains polished, concise and timely reviews and opinions, with particular emphasis on those articles published in the past two years. In addition to describing recent trends, the authors are encouraged to give their subjective opinion of the topics discussed. In Current Opinion in Immunology we help the reader by providing in a systematic manner: 1. The views of experts on current advances in their field in a clear and readable form. 2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. Current Opinion in Immunology will serve as an invaluable source of information for researchers, lecturers, teachers, professionals, policy makers and students. Current Opinion in Immunology builds on Elsevier''s reputation for excellence in scientific publishing and long-standing commitment to communicating reproducible biomedical research targeted at improving human health. It is a companion to the new Gold Open Access journal Current Research in Immunology and is part of the Current Opinion and Research(CO+RE) suite of journals. All CO+RE journals leverage the Current Opinion legacy-of editorial excellence, high-impact, and global reach-to ensure they are a widely read resource that is integral to scientists'' workflow.
