  • 專業解析

    法氏囊(Bursa of Fabricius)是鳥類特有的免疫器官,位于洩殖腔(肛門)後上方,呈囊狀結構。它由意大利解剖學家赫羅尼姆斯·法布裡奇烏斯(Hieronymus Fabricius)于17世紀首次描述并命名。該器官在幼鳥的免疫系統發育中起關鍵作用,是B淋巴細胞(B細胞)分化成熟的主要場所。B細胞負責産生抗體,是適應性免疫應答的核心組成部分。

    研究表明,法氏囊的功能與哺乳動物的骨髓類似,但具有物種特異性。雛雞在孵化後若被摘除法氏囊,會導緻體液免疫功能嚴重缺陷,這為免疫學家理解B細胞發育機制提供了重要模型。現代免疫學研究證實,法氏囊基質細胞分泌的多種細胞因子(如BMP4、SCF)通過Notch信號通路調控B細胞的分化過程。
