The altered immune receptors weren't effective.

Here's how shape works in normal receptors.

Because our pheromones matched our olfactory receptors.

It's these receptors that are actually very important.

Well, that's because you've got receptors in your skin, touch and pain receptors, going back into your brain and saying Don't worry, you're not being touched.

These are just like the receptors on the surfaces of your cells.

Very complex processes with very complex chemicals that fit into very complex receptors.

They are coupled to light receptors similar to the ones in your eyes.

And so they lock into those receptors, and they jam recognition of the real thing.

Because, genetically, they knocked out the receptors for a chemical in the brain called dopamine.

So, you'll have insulin to attach to the receptors, and so the glucose can be processed properly.

But because this individual lacks receptors to hear that testosterone, the body doesn't react to the testosterone.

So these little mice without endorphin receptors in their brains will naturally not call for their mothers.

But let's say another method would be, the virus convinces just based on some protein receptors on it, or protein receptors on the cells and obviously this has to be kind of a Trojan horse type of thing.

In this situation, the receptors have difficulty binding to the insulin. and glucose does not enter the cell.

But, there's multiple lines of attack here, and usually the first is drugs that help resensitize the receptors.

It's called harm reduction, and it involves, among other things, providing clean needles and syringes, offering opioid substitution therapy and other evidence based treatments to reduce drug dependence.

Your heart has receptors for this hormone, and oxytocin helps heart cells regenerate and heal from any stress induced damage.

So, once again let me draw some glucose floating by... some insulin receptors on the cell, and let's have some insulin.

So, if you add enough insulin, there may be enough to bind with the insulin receptors and cause some glucose absorption.

It still freaks me out every time I eat it, but it has a unique ability to mask certain taste receptors on your tongue, so that primarily sour taste receptors, so normally things that would taste very sour or tart, somehow begin to taste very sweet.

When the body is touched, receptors in the skin send messages to the brain causing the release of chemicals such as endorphins.

By seven months of gestation, the fetus' taste buds are fully developed, and its olfactory receptors, which allow it to smell, are functioning.

Because genetically they knocked out the receptors, the chemical binding sites in the brain, for endorphins and endorphins are indigenous morphine like substances endorphins are our own natural painkillers.

In this situation there is nothing to bind to these receptors, so the glucose channels won't be opened up and the glucose won't be able to enter into the cell

And we're understanding there're growth factors that go on, parts of these NR2B receptors are turned up, and the entire plasticity machinery is turned on along with these new baby cells.

So a tumor expresses chemokine receptors, and another organ a distant organ somewhere in the body will have the corresponding chemokines, and the tumor will see these chemokines and migrate towards it.

And when it goes crazy, what it does is it activates all this machinery down here, and the effect of all that machinery is to put in more of these ordinary boring receptors.

What that means is if you can tickle the fancy of this NMDA receptor, you'll put in more of these ordinary AMPA receptors into the synapse, and then the synapse will become stronger.

So our Pancreas is producing insulin and putting it into our bloodstream, so it's there to be used. but a situation can arise where the receptors are not working properly, and they have been desensitized to insulin.

Those little blue dots on the top are the transmitters released by the axon, and then they activate all of these receptors, and all of that machinery in the next neuron, and ultimately that causes the neuron to fire.

let me draw my simple version of a cell, and let me draw the blood stream going by... right over here and draw the glucose in the blood stream, floating by, and then I have my insulin receptors on the surface of the cell.

This situation is Type I Diabetes where you have glucose, so there you have energy and you have properly functioning insulin receptors, you just don't have insulin to unlock the gates for the glucose to actually go into the cell the other scenario that you could imagine happening is...let me draw the cell again and the blood stream and obviously that is one of trillions of cells in the human body.
