肺结节病患者的支气管肺泡灌洗液(BAL)中的T淋巴细胞的研究已做了许多工作,但有关肺泡巨噬细胞的研究相对地进行较少,而后者在慢性肺间质炎症性疾病中起着重要作用。以往研究发现巨噬细胞表面类la(DR)抗原的表达,在巨噬细胞和致敏的T淋巴细胞之间的相互作用起关键作用,而且对许多巨噬细胞和淋巴细胞的免疫功能来说是必需的。以往研究还表明,巨噬细胞表面DR抗原的表达在以激活的T淋巴细胞为特征的疾病中是增加的。本文测定了正常不吸烟
Much work has been done on the study of T lymphocytes in bronchoalveolar lavage fluid (BAL) in patients with pulmonary sarcoidosis, but there are relatively few studies on alveolar macrophages, and the latter is relatively rare in chronic pulmonary interstitial inflammatory Disease plays an important role. Previous studies have found that the expression of macrophage surface-like la (DR) antigens plays a key role in the interaction between macrophages and primed T lymphocytes and that for the immune function of many macrophages and lymphocytes is compulsory. Previous studies have also shown that the expression of DR antigens on the surface of macrophages is increased in diseases characterized by activated T lymphocytes.
