肺除具有气体交换和代谢功能外,还是机体内环境与生活环境之间必不可少的一道生物屏障设施。本文旨在复习有关呼吸道之免疫应答的表现形式,以便了解此种机理在肺的防御作用以及免疫参与肺部疾病中所起的作用。一、呼吸道淋巴组织的特点Bienenstock等在动物和人支气管粘膜上皮之下所观察到的淋巴组织称为支气管相关连的淋巴组织(Bronchus associated lymphoidtissue,BALT)。家兔BALT滤泡的复盖上皮
In addition to the lungs with gas exchange and metabolic functions, or the body environment and living environment is essential between a biological barrier facilities. The purpose of this article is to review the manifestations of the respiratory response to the immune system in order to understand the role of this mechanism in the defense of the lungs and immune involvement in lung diseases. First, the characteristics of airway lymphoid tissue Bienenstock other animal and human bronchial epithelium observed under the lymphoid tissue known as bronchial lymphoid tissue (Bronchus associated lymphoid tissue, BALT). Rabbit BALT follicular covered epithelium
