The University of Alabama just did another kidney transplant experiment that lasted a week.

But this one has been going for more than a month, and they just got approval to extend the experiment for up to another month.

但这个实验已经进行了一个多月了,而且他们刚刚得到批准,可以将这个实验再延长一个月Nm[L1Z-h)%~

Back in early 2022, a team at the University of Maryland transplanted a pig heart into a living person—a man named David Bennett.

早在2022年初,马里兰大学的一个研究小组就将一颗猪的心脏移植到了一个活人身上——这个接受移植的人叫大卫·贝内特QGe8bgY=l-e2J

Bennett lived for two months with the new organ, but ultimately it failed and he passed away.

贝内特用这个新器官活了两个月,但最终还是以失败告终,他去世了B&y)=2c^McKHuAsa@,R

The exact reason for the failure is still unclear, but a previously undetected pig virus may have played a role.

失败的确切原因尚不清楚,但一种以前从未被发现的猪病毒可能起了某种作用6@d%YzY_Bo!_af@6g-]@

So there's still, you know, a lot of mystery in terms of what happened.

关于发生了什么,仍然存在很多谜团CqB_SMURkRX

But what we do know is the heart suddenly stopped working.

但我们知道的是,心脏突然停止了工作^H!kmUVKBO

One of the things that was present at that time was an infection, a virus called cytomegalovirus, CMV, that came from the pig and stayed in the pig tissue and never infected any of the human tissue or cells.

ZRQ-ltRGx,!bJQCNpBR

当时存在一种感染, 感染是由巨细胞病毒(CMV)造成的,这种病毒来自猪,并停留在猪组织中,从未感染过任何人类组织或细胞Qw~&rRPy0=[2ODWlY

But we know from decades of primate work, when the organ…when the pig heart is infected with that virus, that it causes the heart to start to go rapidly downhill.

不过,我们从几十年的灵长类动物研究中了解到,当猪的器官--猪的心脏感染了这种病毒,会导致心脏开始迅速坏死.!eHIz#iauUZ7

@3A8o@3g9vs*V,x~mP

So, we think that played a role, but there also appeared to be some rejection as well.

我们认为这种病毒起到了某些作用,但似乎也存在某些器官排斥b&cCE!]OX@Psm

Montgomery and his team take these risks seriously.

They have developed a more accurate test to screen for pig viruses, and they monitor the recipient and anyone who comes into contact with them very closely.

Decedent experiments like the one they are currently doing will be crucial to showing the FDA that these pig organs are safe and effective enough for clinical trials in living people.

他们目前正在进行的是死人实验,这对于向食品药品监督管理局证明将猪器官移植到活人体内的临床试验是安全有效的至关重要|KZoe~.!I)])e&y

For Montgomery, it’s a personal mission as much as a professional one.

对蒙哥马利来说,这既是一项个人任务,也是一项职业任务*2wN2dc[626]

As I laid for a month in the ICU waiting for a human organ, it came even more clearly into focus that this is what I needed to devote the rest of my life to.

当我在重症监护室躺了一个月,等待人体器官移植时,我更加清楚地意识到,这就是我需要为之奉献余生的事业T30DIrMmnFWX0D

And this, has become the thing that I really feel is a chance at really changing the future in a really significant way for all the people who…I share their level of, of desperation, you know, and understand it, when you're waiting for a transplant, it's a really extremely vulnerable and difficult position to be in.

我真的觉得这是一个改变未来的机会,对所有的人来说,这是一个非常重要的方式,我和他们一样绝望,并且理解这种绝望,当你在等待移植时,这是一个非常脆弱和困难的处境m(dvrVX-,1A
