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?

And between this muscle, they found nervous tissues, a lot of nervous tissues, which penetrate actually the muscle penetrate the submucosa, where you have all the elements for the immune system.

like an immune system, and we're learning from gene regulation and biological development.

When the immune system responds to the infection, even more lung damage may occur.

In terms of physiology, CD molecules can act in numerous ways, often acting as receptors or ligands (the molecule that activates a receptor) important to the cell.

My oncologist and I talk a lot these days because I try to keep my talks technically accurate.

So if you look at the cell like that from the immune system, they're actually moving all over the place.

In autoimmune diseases, the goal would be to shift the self destructive TH1 response (with its associated cytotoxic T cell activity) to a non destructive TH2 response.

There are two major subtypes of T cells the killer T cell and the helper T cell.

So, you take the drop of blood, no further manipulations, you put it on a little device, the device filters out the blood cells, lets the serum go through, and you get a series of colors down in the bottom there.

Cells...

Microglia are the resident immune cells of the central nervous system (CNS) and have a critical role in host defense against invading microorganisms.

So, I call them Gandhi neurons, or empathy neurons.

Here, the fungi actually grow inside plant cells, allowing them to exchange nutrients with their hosts, while sending signals that suppress the plant immune system.

I'm talking about the cells of the body or most of the body.

Damage is believed to be caused, at least in part, by attack on the nervous system by a person's own immune system.

And then the transducer then makes the output cells send the code on up to the brain, and the result is a retinal prosthetic that can produce normal retinal output.

My body's an accumulation of ideas too the idea of skin cells, the idea of brain cells, the idea of liver cells.

In prostate cancer, the cells of these prostate glands mutate into cancer cells.

This is my stem cell line that developed out of some blood cells.

Another, which has been discovered by various researchers at Emory and at Davis and so on, is that compassion enhances our immune system.

Older phellem cells are dead, as is the case with woody stems.

We'll see that there are helper T cells and there are cytotoxic T cells.

Neurons ... communication.

You have neutrophils.

These are normal cells.

So, remember that hair cell?

Cells, Howard?

So in there, we said, well, there's an inflammatory response, which I'm actually going to talk about after we do videos on the specific immune system.

MHC molecules mediate interactions of leukocytes, also called white blood cells (WBCs), which are immune cells, with other leukocytes or with body cells.

And then what they did in October is they took skin cells, turned them into stem cells and began to turn them into liver cells.

The observation that stem cells, as master cells, could give rise to a whole variety of different cell types heart cells, liver cells, pancreatic islet cells captured the attention of the media and the imagination of the public.

Last year, this group was able to take all the cells off a heart,

So let me draw some skin cells.

Let's look at a healthy liver cell, a healthy hair cell, and a cancerous cell.

It's called the basket cell.

There are other cells in my neighborhood. They'll recognize that, and say, you know, I'm going to stop growing a little bit.
