淋巴细胞的B 细胞能产生抗体,激活免疫反应。它的增殖因子的基因,已由日本京都大学的本庶教授和瑞典卡罗林斯卡研究所的伊·斯培林斯克博士共同研究提取出来,并首次成功地阐明了整个基因的结构。他们把该基因产生的增殖因子命名为白细胞介素4。该物质在体内具有促进抗体产生的作用,如能应用于临床,可预期为癌症等多种疾病的治疗开辟新的途径。B 细胞能借助T 细胞所分泌的物质增殖,产生 Lymphocyte B cells produce antibodies that activate the immune response. The gene of its proliferation factor has been researched and researched by Professor Ben Shu of Kyoto University in Japan and Dr. I.Spelinowsk of the Karolinska Institute in Sweden, and for the first time successfully elucidated the structure of the entire gene. They named the gene for the proliferation factor interleukin-4. The substance has the role of promoting antibody production in the body and can be expected to open up new avenues for the treatment of a variety of diseases such as cancer if it can be used clinically. B cells can be generated by the proliferation of T cells secreted substances
