很多爱猫人都面临着进退两难的境地:他们想抱起猫咪紧紧搂着它们,但如果这样做的话,他们的眼睛就会肿起来,而且开始打喷嚏。医生可以治疗猫过敏的症状,但迄今为止还没有根治这种过敏的疗法。因此研究者们努力寻找着其他的解决途径。
Many cat lovers live with a dilemma: they want to pick up the animals and hold them close, but if they do, their eyes will swell up and they'll start sneezing. Doctors can treat the symptoms of cat allergies, but so far no cure is available. Researchers are, therefore, trying to look at the problem in different ways.
过敏是免疫系统对那些其实并不能伤害人体的物质做出的过度反应。目前根治过敏症的方法就是持续给患者注射一定剂量的过敏原,数年后就能让免疫系统对过敏原进行识别。但“问题是这就像小剂量的毒药一样,”洛杉矶加利福尼亚大学的博士安德鲁撒克逊对《卫报》如是说,身体要忍受“你自己发起的进攻所造成的伤害。”他说他的团队则把兴趣放在寻找一种能对免疫系统进行训练,却不会伤害人体的方法。
Allergy is an overreaction of the immune system to substances that aren't really able to harm the body. The current method of curing allergies is to give a person small doses of an allergen over a period of years in order to train the immune system to recognize it. But "the problem is that it's like giving a small dose of poison," Dr Andrew Saxon of the University of California at Los Angeles told The Guardian. The body suffers "damage because of your own attack". Instead, he said, his team was interested in finding a way of training the immune system without making people sick.
撒克逊的方法是从猫身上取得一种蛋白质,再取得人体的某种蛋白,将两者结合生成一种完整的分子。当这种物质进入到人体,所发生的反应就会受这种合成分子的控制。一方面猫的蛋白质导致过敏反应,让人体生出一种叫免疫球蛋白E的抗体。而另一方面,人体蛋白则安抚着免疫系统。最终结果就是对猫的蛋白能有更好的抵抗,但却不会有极端的过敏反应。
Saxon's method is to combine a protein from cats with one from humans into a single molecule. When the substance enters the human body, it forces a reaction which the hybrid molecule itself controls. The cat protein, on the one hand, causes an allergic reaction, making the body produce an antibody called immunoglobulin E. The human protein, on the other hand, calms the immune system down. The end result is better resistance to the cat protein without an extreme allergic reaction.
撒克逊在老鼠身上实验了他的方法。这些老鼠经过基因工程改造后对猫过敏,但仅仅(采用了撒克逊的疗法)过了一个月,这些老鼠就不再对猫过敏了。这一方法还需要进行人体实验并作改进,所以爱猫者还要等待数年,这一疗法才能普遍适用。同时,撒克逊还想寻找根治食物过敏的方法。迄今为止,经验证,把果仁蛋白与人体蛋白结合十分困难,但撒克逊相信他根治猫过敏的方法能够适用于这一问题。
Saxon tested his method on mice that were genetically engineered to be allergic to cats. After only a month, the mice were free of their allergy. The process still has to be tested on humans and perfected, so cat lovers will have to wait several years until the cure is widely available. In the meantime, Saxon wants to look for a cure for food allergies. So far, it has proved difficult to combine proteins from nuts with human proteins, but Saxon believes his method of curing cat allergies can be extended to meet this situation.
