And these chemicals are easily absorbed through amphibians' permeable skin, causing immunosuppression, or a weakened immune system, and developmental deformities.

After HlV penetrates the body's mucosal barriers, it infects immune cells to replicate.

It is a drug for people, but the reason is it suppresses the immune system.

We'd much rather re educate the immune system to be selective, to do what we want it to do and let the rest of the immune system do what it's supposed to do in terms of protecting us.

I was absolutely enthralled and amazed at what they looked like.

And I guess I would say it's about time, because for the last 50 years the way that we have treated these kinds of auto immune diseases is through something called immunosuppression.

So it's very valuable to have that tool in our armamentarium.

In experimental feeding in monkeys you can see that it actually downregulates a specific immune system modulator.

This is just a vitamin shot to boost your immune system.

Notice these other, smaller protuberances.

Their immune system.

Besides being sort of more sophisticated and elegant, there's a real reason for this and that is that the immunosuppression, over here, is dangerous, because blocking the immune system means that it blocks the immune system from protecting you from infection.

It basically is an approach that says

It's not constrained by living within the body that gave rise to it.

This is one of those signals that the immune system sees in patients who have a disease called type 1 diabetes.

Unfortunately there are a lot of these signals and there are a lot of mistakes to be made and our immune systems aren't perfect.

Hits the body hard like a quart of alcohol, and then it eradicates the immune system.

I had to do that properly.

Let me tell you a little bit about the scale.

DNA repair genes are more active in these animals.

I don't believe it. Nothing could be immune to that.

Sir, the restrains!

The big change in our understanding of drivers of chronic health in the rich developed world is how important chronic stress from social sources is affecting the immune system, the cardiovascular system.

On three you jump as high as you can!

The chain of command is responsible for...

So we don't want to do that.

It's a hormone.

Still think she's immune?

And on, and on, and on, there are over 80 of these auto immune diseases.

What I thought about was, what caused the diabetes?

And so you have a very strong natural selection once immune systems learn what this virus is and we'll talk more about what learning means for an immune system. that they'll start attacking these guys, right?

Blow the dampeners!

Full power to containment!

No time for the immune response.

About 5 percent of us have one of these auto immune diseases.

It's not a cure. Just a strong antibiotic to build up resistance.

Okay, we can start with that. I say no.

Bellini's lymphocemia. It's an autoimmune disease.

Another way by which microbes can affect the brain is by activation of the immune system.

Sooner or later. Understand they found a rhesus monkey at Dietrich immune.

If we go down the small pathway a little bit farther, we're entering the era of nanomedicine, the ability to make devices super small to the point where we can design red blood cells or microrobots that will monitor our blood system or immune system, or even those that might clear out the clots from our arteries.

They basically create a cache of weapons for your immune system which you can deploy when needed.

Why?

Let's flip the table yet again

Want an immunity check on this one, Doctor?
