他认为免疫系统是由10~(12)淋巴细胞和10~(20)抗体组成,具有双重的特性,表现在(1)T、B 淋巴细胞的作用部份是协同的,部份是对抗的。(2)淋巴细胞识别抗原时的反应可以是正的(如增值、激活、抗体分泌)也可以是负的(如抑制和麻痹)。(3)抗体分子有识别和被识别的特性,它们不但有结合部位可以识别抗原,而且有抗原决定簇可以被其它抗体分子的结合部位所识别,这种抗体分子兼指循环抗体和淋巴细胞 He thinks the immune system is made up of 10-12 lymphocytes and 10-20 antibodies and has the dual characteristic that the effects of (1) T and B lymphocytes are partly synergistic and partly antagonistic . (2) The response of lymphocytes to antigen recognition may be positive (eg, value added, activation, antibody secretion) or negative (eg, inhibition and paralysis). (3) Recognition and identification of antibody molecules, they not only have binding sites that recognize antigens but also epitopes recognized by the binding sites of other antibody molecules, both circulating antibodies and lymphocytes
