In summary, these clues span genetic and environmental factors as well as both the innate and adaptive immune system.

总之，致病机制可能涉及遗传和环境因素，还有先天性和适应性免疫系统。

B and T cells make up the adaptive immune system, while NK cells are part of the innate immune system.

B细胞和T细胞组成了适应性免疫系统，而NK细胞是固有免疫系统的一部分。

The adaptive immune system responds to antigens.

适应性免疫系统对抗原作出反应。

Immunology is the study of the immune system, which includes the innate and adaptive immune system in humans, for example.

免疫学是对免疫系统包括人体非特异性免疫及获得性免疫系统的研究。

People whose innate and adaptive immune systems go ham on a pathogen tend to end up with more severe symptoms. Though, again, balance seems to be key.

先天免疫系统和适应性免疫系统在病原体上失灵的人往往会出现更严重的症状。不过，平衡似乎是至关重要的。

Still, there are other ways the adaptive immune system could be suppressing a person's symptoms. Like, research also suggests that T cells stay cooler under pressure in asymptomatic individuals.

然而，适应性免疫系统还可以通过其他方式抑制患者的症状。比如，研究还表明，在无症状的患者中，T细胞在压力下会保持凉爽。

The adaptive immune system is in charge of creating specialized proteins called antibodies that attack and destroy specific invaders but in autoimmune disorders, the adaptive immune system mistakenly attacks the body's own healthy tissues.

适应性免疫系统可以产生一种蛋白质“抗体”来攻击特定的入侵者，但患自身免疫性疾病时，适应性免疫系统会错误地攻击自身的健康组织。

The dendritic cell, which is part of the innate immune system, bridges the innate and adaptive immune responses when it presents the antigen to the T cell - part of the adaptive immune system.

树突状细胞，作为固有免疫系统的一部分；在呈递抗原给T细胞时，将固有和适应性免疫反应连接了起来（是适应性免疫的一部分）。

Now if a pathogen does manage to get past the first line of defense, we have another layer of protection, the adaptive immune system, which is more complex and targeted than our bouncer.

现在，如果病原体确实设法通过了第一道防线，我们就有了另一层保护， 即适应性免疫系统， 它比我们的保镖更复杂、更有针对性。

Your immune system is constantly reading name tags, and when one is recognized as being on the no-entry list, the adaptive immune system creates special immune cells to attack, which are specialized white blood cells called lymphocytes.

你的免疫系统不断地读取名字标签，当一个人被识别为在禁止进入的名单上时， 适应性免疫系统会产生特殊的免疫细胞来攻击， 这些细胞是被称为淋巴细胞的特殊白细胞。
