A Quote by Luc Montagnier
What seems to be clear to me is that after the primary infection most of the cells die indirectly, but at the later stage, when the viral load is very high, the virus kills a lot of cells directly.

There are two main types of immunity to an infection. Innate immunity comes from circulating cells that attack any invader the body views as foreign. Adaptive immunity is specific to the pathogen presented. Through adaptive response, immune cells are programmed to secrete antibodies that are primed to target a viral invader.
If you inhale a millionth of a gram of plutonium, the surrounding cells receive a very, very high dose. Most die within that area, because it's an alpha emitter. The cells on the periphery remain viable. They mutate, and the regulatory genes are damaged. Years later, that person develops cancer. Now, that's true for radioactive iodine, that goes to the thyroid; cesium-137, that goes to the brain and muscles; strontium-90 goes to bone, causing bone cancer and leukemia.
Whatever the occasion, do not neglect alcohol. No other refreshment will do. Yes, alcohol kills brain cells, but it's very selective. It only kills the brain cells that contain good sense, shame, embarrassment, and restraint.
Most of our brain cells are glial cells, once thought to be mere support cells, but now understood as having a critical role in brain function. Glial cells in the human brain are markedly different from glial cells in other brains, suggesting that they may be important in the evolution of brain function.
Both in Britain and America, huge publicity has been given to stem cells, particularly embryonic stem cells, and the potential they offer. Of course, the study of stem cells is one of the most exciting areas in biology, but I think it is unlikely that embryonic stem cells are likely to be useful in healthcare for a long time.
Conversational intelligence is hard-wired into every single human-being's cells. It's the way the cells engage with each other. Believe it or not, cells talk to each other. The immune system talks to the cells.
One of the first papers I wrote at the University of Wisconsin, in 1977, was on stem cells. I realized that if I changed the environment that these cells were in, I could turn the cells into bone, and if I changed the environment a bit more, they would form fat cells.
Probably all of us have random rogue cancer cells floating around in our bodies but by and large, in the majority of cases, our immune system circulates and acts as a surveillance mechanism and kills off those few tumor cells.
Lately, however, on abandoning the brindled and grey mosquitos and commencing similar work on a new, brown species, of which I have as yet obtained very few individuals, I succeeded in finding in two of them certain remarkable and suspicious cells containing pigment identical in appearance to that of the parasite of malaria. As these cells appear to me to be very worthy of attention ... I think it would be advisable to place on record a brief description both of the cells and of the mosquitos.
Your brain forms roughly 10,000 new cells every day, but unless they hook up to preexisting cells with strong memories, they die. Serves them right.
Brain cells create ideas. Stress kills brain cells. Stress is not a good idea
A human body is a conversation going on, both within the cells and between the cells, and they're telling each other to grow and to die; when you're sick, something's gone wrong with that conversation.
People lose fifty million skin cells every day. The cells get scraped off and turn into invisible dust, and disappear into the air. Maybe we are nothing but skin cells as far as the world is concerned.
There are cells in the brain that respond to faces. This is one of the reasons that I deal with portraiture. We can learn a lot about our perception of facial expression from the behavior of these cells.
When the finely tuned balance among the different parts of bodies breaks down, the individual creature can die. A cancerous tumor, for example, is born when one batch of cells no longer cooperates with others. By dividing endlessly, or by failing to die properly, these cells can destroy the necessary balance that makes a living individual person. Cancers break the rules that allow cells to cooperate with one another. Like bullies who break cooperative societies, cancers behave in their own best interest until they kill their larger community, the human body.
What do cells do when they see a broken piece of DNA? Cells don't like such breaks. They'll do pretty much anything they can to fix things up. If a chromosome is broken, the cells will repair the break using an intact chromosome.
