However, for a period ranging from a few months to several years, during which time the patient may look and feel completely healthy, the virus continues to replicate and destroy T cells.
Other drugs prevent the virus from maturing or assembling, causing HIV to be unable to infect new cells in the body.
But HIV hides out somewhere our current drugs cannot reach it: inside the DNA of healthy T cells.
Most T cells die shortly after being infected with HIV.
So even if we could wipe out every HIV virus from an infected person's body, one of those T cells could activate and start spreading the virus again.
One research approach involves using a drug to activate all cells harboring the HIV genetic information.
This would both destroy those cells and flush the virus out into the open, where our current drugs are effective.
Another is looking to use genetic tools to cut the HIV DNA out of cells genomes altogether.
Once implanted, the cells that are to become the placenta secrete a hormone that signals to the ovulated follicle that there is a pregnancy in the uterus.
In the laboratory, the identified eggs are stripped of surrounding cells and prepared for fertilization in a petri dish.
Common convention is to transfer the embryo three days after fertilization, when the embryo has eight cells, or on day five, when the embryo is called a blastocyst, and has hundreds of cells.
Execution and deportation were often the punishments of choice, and those who were locked away faced hours of solitude in filthy cells.
This ingredient comes from skin cells called melanocytes and takes two basic forms.
When skin is exposed to UV for long periods of time, the UV light damages the DNA within our cells, and skin starts to burn.
If that damage is severe enough, the cells mutations can lead to melanoma, a deadly cancer that forms in the skin's melanocytes.
When it's exposed to UV light, that triggers special light-sensitive receptors called rhodopsin, which stimulate the production of melanin to shield cells from damage.
During our waking hours, our cells are busy using up our day's energy sources, which get broken down into various byproducts, including adenosine.
It works by using cerebrospinal fluid to flush away toxic byproducts that accumulate between cells.
Lymphatic vessels, which serve as pathways for immune cells, have recently been discovered in the brain, and they may also play a role in clearing out the brain's daily waste products.
Normally, amyloid beta is cleared away metabolized by microglia, the janitor cells of our brains.
Our microglia janitor cells become hyper-activated, releasing chemicals that cause inflammation and cellular damage.
In slow-wave deep sleep, our glial cells rinse cerebral spinal fluid throughout our brains, clearing away metabolic waste that accumulated in our synapses while we were awake.
And some, amazingly, are still pursuing fuel cells, but I think that won't last much longer.
EM: Well, when it's running at full speed, you can't actually see the cells without a strobe light.
In Guillain-Barré, your immune system attacks your nerve cells it can partially or even totally paralyze you.
This is made of a tight mesh of cells which separate blood vessels from the brain, and block everything except for a specific set of particles, including water molecules and some gases.
In addition, there are ways where you can take away immune cells from the body, train them, engineer them and put them back into the body to fight cancer.
Even a cancer as small as one centimeter in diameter harbors over a hundred million different cells.
So even if you have a drug that's highly effective, that kills almost all the cells, there is a chance that there's a small population that's resistant to the drug.
Even more importantly, we need a method to be able to detect cancers before they're 100 million cells in size.
