肺肉瘤样病是一种肉芽肿样疾病,是由于活化T_4~+T 淋巴细胞在下呼吸道聚积而成。β_2-微球蛋白是一种与细胞膜上的HLA 抗原有关的低分子量(1.18KD)蛋白质。除成熟红细胞外,所有的细胞都可产生这种蛋白质。为了探讨β_2-微球蛋白与淋巴细胞之间的关系,作者对活动性肺肉瘤样病患者的支气管肺泡灌洗液(BAL)中β_2-微球蛋白水平、T 细胞亚群与病程的关系进行了研究.本研究包括131例肺肉瘤病患者,23例
Pulmonary sarcoidosis is a granulomatous disease that results from the accumulation of activated T 4 + T lymphocytes in the lower respiratory tract. β 2-microglobulin is a low molecular weight (1.18 kD) protein associated with the HLA antigens on the cell membrane. In addition to mature red blood cells, all cells can produce this protein. In order to investigate the relationship between β_2-microglobulin and lymphocytes, the authors investigated the relationship between β_2-microglobulin and T-cell subsets and duration of disease in patients with active pulmonary sarcoidosis in bronchoalveolar lavage fluid (BAL) The study included 131 patients with pulmonary sarcoidosis, 23 patients
