Abstract

Staphylococcus aureus strain Cowan I, Haemophilus influenzae, and Branhamella catarrhalis that stimulate human B lymphocytes, but not T lymphocytes, were used to study the B lymphocyte function in patients with hypogammaglobulinaemia. Lymphocytes from two patients with no circulating B cells were not stimulated to increased DNA synthesis by these bacterial mitogens. The lymphocytes of six patients with hypogammaglobulinaemia and normal numbers of circulating B cells responded to the bacterial mitogens but in five patients the response was decreased in comparison with healthy controls.

摘要

用能刺激人B淋巴细胞而不刺激T淋巴细胞的金黄色葡萄球菌考恩I株、流感嗜血杆菌和卡他布兰汉菌,来研究低丙种球蛋白血症患者的B淋巴细胞功能。两名无循环B细胞患者的淋巴细胞,未被这些细菌促有丝分裂原刺激而增加DNA合成。六名低丙种球蛋白血症且循环B细胞数量正常患者的淋巴细胞对细菌促有丝分裂原产生反应,但与健康对照相比,五名患者的反应减弱。
