抗原和抗體的區(qū)別
2019-12-11 19:34
這血清里含有抗體。當(dāng)然也含有抗原，可以刺激機(jī)體產(chǎn)生免疫反應(yīng)
抗原在體內(nèi)可以引起免疫反應(yīng)?？贵w是由抗原刺激機(jī)體產(chǎn)生的，能與抗原特異性結(jié)合是抗原失去毒性的球蛋白。
也就是說，該教授感染的sars病毒是抗原。使他患病，而另一個(gè)已痊愈的非典病人，由于感染過非典，體內(nèi)產(chǎn)生過抗體。這時(shí)候抗體就在病人的血清中，該教授用權(quán)與病人的血清注射相當(dāng)于注射了抗體，于是抗體消滅了抗原，并就好了。
免疫的過程比較復(fù)雜，一般是這樣的。
抗原經(jīng)過吞噬細(xì)胞處理之后，露出了抗原決定簇，抗原決定簇決定了抗原的特異性。
然后吞噬細(xì)胞將抗原信息船體給T淋巴細(xì)胞，然后T淋巴細(xì)胞吧抗原信息傳遞給B淋巴細(xì)胞。這時(shí)候B淋巴細(xì)胞接受刺激，分裂分化成效應(yīng)B細(xì)胞，和記憶細(xì)胞。效應(yīng)B細(xì)胞立刻合成有關(guān)抗體，使抗原發(fā)生特異性凝結(jié)，就是抗原失效，然后再有吞噬細(xì)胞等吧抗原消滅。
另外當(dāng)相同抗原再次刺激機(jī)體是，記憶細(xì)胞就會(huì)直接分化成效應(yīng)b細(xì)胞，分泌抗體，消滅抗原，這個(gè)過程叫做二次免疫。我們的疫苗應(yīng)用的就是二次免疫效果迅速?gòu)?qiáng)烈的原理。
當(dāng)然也有一些抗原不需要T細(xì)胞，直接有吞噬細(xì)胞處理后呈遞給B細(xì)胞。
The serum contains antibodies. Of course, it also contains antigens, which can stimulate the body to produce an immune response, and antigens can cause an immune response in the body. Antibody is produced by the stimulation of the Antigen, antigen-specific binding to the antigen is the loss of toxicity of Globulin. In other words, the SARS virus that the professor was infected with was an antigen. That made him sick, and another SARS patient who had recovered, because of the SARS, had antibodies in his body. At this point the antibody is in the patient's serum, and the professor uses the same injection as the patient's serum to inject the antibody, so the antibody destroys the Antigen and is cured. The immune process is complicated, and it usually is. The Antigen is then processed by phagocytes to expose the Epitope, which Epitope the specificity of the Antigen. Then the phagocytes pass the antigen information to the lymphocyte, and the lymphocyte pass the antigen information to the lymphocyte. This is when lymphocyte B cells are stimulated and divide into effector b cells and memory cells. EFFECTOR B cells immediately synthesize the relevant antibodies, so that antigen-specific coagulation, that is, antigen failure, and then there are phagocytes and so on Antigen elimination. In addition, when the same antigen is restimulated, the memory cells directly differentiate into effector B cells, secreting antibodies that destroy the Antigen, a process called secondary immunity. Our vaccine is based on the principle that secondary immunity is rapid and strong. There are, of course, some antigens that do not require t cells, but are presented directly to B cells by phagocytes. Well, it's in the high school curriculum. That's what our teacher said
