免疫反应的遗传控制是一个难题,在10～15年前已提出此问题。做免疫学工作而不了解免疫的遗传调控,那是很困难的。因为机体的免疫功能是受遗传控制的,而且这种控制可以表现在不同的水平上。我们可以把这种不同水平的控制与交响乐队进行比较。整个交响乐队所有乐器的声调可以很高,也可以很低。就动物或人而言,对所有各种抗原可以有很高的反应,也可以有很低的反应。第二级水平的反应 Genetic control of the immune response is a problem that was raised 10 to 15 years ago. It is very difficult to do immunological work without understanding the genetic control of immunity. Because the body’s immune function is genetically controlled, and this control can be displayed at different levels. We can compare this different level of control with symphony orchestras. The tone of all the orchestra instruments can be high or low. In the case of animals or humans, all kinds of antigens can have a high response, but also have a very low response. The second level of response
