Lymphocytes from uninfected, nonimmune mice can be stimulated to proliferate and produce antibody to diverse antigens in culture when exposed to the purified protein derivative of tuberculin or unheated tuberculin culture filtrate. Lymphocytes from numerous inbred strains of mice respond to tuberculin, but no true low responder strain has been found as yet. The evidence presented suggests that a subpopulation of B cells, which are distinct from those activated by lipopolysaccharide endotoxin, respond to tuberculin. The results of digestion experiments with insolubilized enzymes suggest that the nonspecific activating principles in tuberculin are protein.
当未感染、无免疫力的小鼠淋巴细胞暴露于结核菌素纯蛋白衍生物或未加热的结核菌素培养滤液时,可在培养物中被刺激增殖并产生针对多种抗原的抗体。许多近交系小鼠的淋巴细胞对结核菌素产生反应,但尚未发现真正的低反应品系。所提供的证据表明,与由脂多糖内毒素激活的B细胞不同的一个B细胞亚群对结核菌素产生反应。用不溶性酶进行的消化实验结果表明,结核菌素中的非特异性激活成分是蛋白质。
