These are released into the patient's blood system.

这些细小部分要放入病人的血液系统中。

The cancer would outfight patients' weak immune systems, said Olja Finn.

奥利娅·芬恩说，癌症会打败患者脆弱的免疫系统。

This takes over the heart's job, generating enough force to push blood through the patient's circulatory system.

这接管了心脏的工作，产生足够的力量来推动血液并把它泵入患者的循环系统。

Most existing treatments focus on modulating or suppressing a patient's immune system.

大多数现有治疗方法都集中于调节或抑制患者的免疫系统。

Antiviral therapies could reduce the amount of EBV circulating in patients' immune systems.

抗病毒疗法可以减少患者免疫系统中循环的 EBV 数量。

CAR-T is named for an antigen receptor that researchers add to T-cells to trick the patient’s immune system into attacking.

CAR-T 以一种抗原受体命名，研究人员将其添加到 T 细胞中以诱使患者的免疫系统发动攻击。

She said new drugs that get the patient's own immune system to fight the cancer could help make the death rate fall even more.

她表示，让患者自身免疫系统对抗癌症的新药可能有助于进一步降低死亡率。

Since some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching.

由于一些抗原可以触发患者的免疫系统攻击输入的血液，因此安全的输血依赖于仔细的血型鉴定和交叉配型。

The next step was to understand how, in a small number of people, the virus can turn a patient's own immune system against them.

下一步是了解病毒如何在少数人中使患者自身的免疫系统对他们产生抵抗。

And in about 400 of 470 documented cases, the transplanted bacterial community quickly became dominant, causing the patient's digestive system to recover and stabilize, though scientists still don't know exactly how that happens.

而在 470 个有记录的病例中，大约有 400 个病例，移植的细菌群落很快就成为主导，使患者的消化系统恢复并稳定下来，尽管科学家们仍然不知道这究竟是如何发生的。

And in 411 of 473 documented cases, the transplanted bacterial community quickly became dominant, causing the patient’s digestive system to recover and stabilize (though scientists still don’t know exactly how that happens).

在 473 例记录在案的病例中，有 411 例移植的细菌群落迅速占据主导地位， 导致患者的消化系统恢复并稳定下来（尽管科学家们仍不清楚这是如何发生的）。

One of the sessions at this year's meeting of the American Association for the Advancement of Science in Denver therefore looked into how transplanted beta cells might be made hypoimmunogenic—in other words, invisible to a patient's immune system.

因此，在今年在丹佛举行的美国科学促进会会议上，其中一个会议探讨了如何使移植的β细胞具有低免疫原性，换句话说，让患者的免疫系统无法察觉。

And this information is already helping tailor treatments to patients' own unique immune systems. Vaccines put the body on high alert for a threat, so a cancer vaccine could boost the concentration of a tumour's neoantigens, switching on the immune system.

这些信息已经在帮助为患者自身独特的免疫系统量身定制治疗方案。 疫苗让身体对威胁保持高度警惕，因此癌症疫苗可以提高肿瘤新抗原的浓度， 从而启动免疫系统。
