美国人类基因组科学公司宣称,他们已发现一种可用于治疗各种疾病（包括癌症和艾滋病）的免疫系统刺激物。这种称为B淋巴细胞刺激物（BLyS）的蛋白能刺激B细胞产生抗体,并将抗体释放到血液中抵抗感染。该公司Haseltine说:“我们发现了能使B细胞分裂和生长并释放其抗体的信号,从而解决了免疫学中一个至今悬而未决的根本问题。”他指出,人体内约有1千万种B细胞,它们对特定病毒或细菌产生不同的抗体。当抗原进入,并被正确地提呈至某种B细胞时,这种B细胞就会迅速增加。
Human Genome Sciences, a U.S. company, claims it has found an immune system stimulator that can be used to treat various diseases, including cancer and AIDS. The protein, called B-lymphocyte stimulator (BLyS), stimulates B-cells to produce antibodies and release the antibodies to the bloodstream to fight the infection. Haseltine, the company, said: “We have uncovered a fundamental problem in immunology that has so far been unanswered in the immune system, signaling that we can divide and grow B cells and release their antibodies.” He notes that there are about 10 million B cells in the body , They produce different antibodies to specific viruses or bacteria. When the antigen enters and is correctly presented to some B cell, this B cell increases rapidly.
