  • 专业解析

    法氏囊(Bursa of Fabricius)是鸟类特有的免疫器官,位于泄殖腔(肛门)后上方,呈囊状结构。它由意大利解剖学家赫罗尼姆斯·法布里奇乌斯(Hieronymus Fabricius)于17世纪首次描述并命名。该器官在幼鸟的免疫系统发育中起关键作用,是B淋巴细胞(B细胞)分化成熟的主要场所。B细胞负责产生抗体,是适应性免疫应答的核心组成部分。

    研究表明,法氏囊的功能与哺乳动物的骨髓类似,但具有物种特异性。雏鸡在孵化后若被摘除法氏囊,会导致体液免疫功能严重缺陷,这为免疫学家理解B细胞发育机制提供了重要模型。现代免疫学研究证实,法氏囊基质细胞分泌的多种细胞因子(如BMP4、SCF)通过Notch信号通路调控B细胞的分化过程。
