在小鼠的淋巴组织和体腔中存在着一小群B细胞,它们在发育、表型和功能上与大多数B细胞群(B-2)不同。这个群体最初被称为“Ly1”,现在被称为“B-1”,作为胎儿来源造血的先天样B细胞群体,负责天然抗体的产生和快速免疫反应,重新引起了人们的兴趣。分子分析已经开始定义胎儿和成人造血,而细胞命运定位研究已经揭示了B-1细胞复杂的发育起源。总之,这些研究提供了对B-1细胞调节和功能的更详细的了解。本综述概述了将B-1细胞定义为天然抗体和产生细胞因子的胎儿源性B细胞的研究,重点介绍了B-1细胞的早期先驱和共同发现者Randy Hardy所做的工作,他的开创性贡献增强了我们对这一神秘B细胞群体的理解。
A small population of B cells exists in lymphoid tissues and body cavities of mice that is distinct in development, phenotype and function from the majority (B-2) B cell population. This population, originally termed “Ly1” and now “B-1”, has received renewed interest as an innate-like B cell population of fetal-derived hematopoiesis, responsible for natural antibody production and rapid immune responses. Molecular analyses have begun to define fetal and adult hematopoiesis, while cell-fate mapping studies have revealed complex developmental origins of B-1 cells. Together the studies provide a more detailed understanding of B-1 cell regulation and function. This review outlines studies that defined B-1 cells as natural antibody and cytokine-producing B cells of fetal origin, with a focus on work conducted by Randy Hardy, an early pioneer and co-discoverer of B-1 cells, whose seminal contributions enhanced our understand of this enigmatic B cell population.
