Why is blood so essential?
blood as a whole is vital to life of any multi-cellular organism. RBCs, or red blood cells transport oxygen to other cells in the body. Blood also has WBCs, Tcells and Bcells that fight infections in our body. Plasma is the fluid part of the blood that brings water to all parts of the body as well as nutrients such as glucose and proteins.

What do T cells produce?
Well. If you get a cut tcells come to help heal it so you feel all better. tcells are really good for your body. They help out all the cuts you have. Good luck................................... with all your cuts. Dont worry tcells where be there always for all of your cuts. once again GOOD LUCK....................................

What is the difference between tcells and bcells?
there are different types of b cell and t cell. both are lymphocytes, a subclass of white blood cell. the t cells are mainly used in identifying antigens and releasing chemicals which attact macrophages (big immune cells which 'eat' antigens), to destroy the antigen. b cells are used in the production of antibodies. when they encounter a new antigen, plasma cells and memory cells are formed from the division of a b cell. the memory cell remembers the antigen and which antibody to use, while the plasma cell makes the antibodies to fight a particular antigen or class of antigens
Asked in HIV and AIDS, Lymphatic System, Immune System
Hiv attacks the body's immune system by destroying what kind of cells?
Once HIV enters the body's blood stream it immediatly starts attacking the body's CD4 cells or your helper t-cells. An average HIV Negative person has roughly around 1200 tcells per every milimeter of blood. How HIV works is that once it's in the blood stream, the HIV virus is a hundred times smaller than one tcell, and the HIV virus attaches itself to the CD4 cell and it sinks into the tcell and uses the cells RNA to copy the HIV virus up to a billion times in 24 hours. But once the HIV uses the tcells RNA the tcell then become paralyzed and dies, and after HIV and destroyed so many tcells that the numbers drop below 200 tcells per milimeter of blood, the body can not naturely fight off infection, and this stage is what you call full blown AIDS.
What do T-cells do?

Will there be a treatment to cure you if you had HIV?
Once you are diagnosed with HIV, or when HIV enters the bloodstream, there is no known cure in which it eliminates the HIV virus from the bloodstream. Usually when you are diagnosed the doctor will then take a blood test to see how much of the virus is in your body per milimeter of blood and also how many CD4 cells (tcells) are also in your bloodstream. If the tests come back that there are more than 200 tcells per millimeter of blood, the Doctor may not put you on HIV medications since your body can still fight infection on it's own. If your tcells are 200 or below, your body can no longer fight off infection and he or she will then start you on HIV medications. Depending on what strain of the virus you have, the Doctor can start you on numerous different kinds of medication combinations. Don't get confused that the HIV medications DO NOT cure HIV from your bloodstream, all it does is stop HIV from attaching to your tcells, and stops the virus from duplicating and keeping the virus undetectable. This way the virus is no longer attacking your immune system, but the virus is hiding mainly in the lymphnodes, and if you were to stop taking the antiretrovirus medications, the virus would come out of remission and start attacking the body again.

Do Kaposi's sarcoma lesions fade away by themselves?
depends on what type of KS you have. I'm going to assume you have KS from an Immune Defiency. In this case, HAART medicine will bring your Tcells Back up , and the KS spots will stop spreading. Or you can do DOXIL chemotherapy, usually 4-6 treatments to treat the cancer. The spots will flatten first, then fade.. They don't usually fade away 100 %.. laser treatment which is expensive can help....

How does the immune system react when given a vaccine?
In the vaccine is a bunch of bs like mercury and other fillers, along with a very very small amount of the enemy. If you are receiving a chicken pox vaccine, then a small amount of the chicken pox virus is in the vaccine, or for the measles vaccine, a small amount of the measles virus is in the vaccine. When the vaccine is injected into your body, it goes to your blood stream. Not only is that your body's highway, it is also where the inspectors work. Immediately, your body notices the foreign substances in your body, and the inspectors alert your immune system to get active. The tcells located in your lymph nodes, (lymph nodes are located throughout your entire body, one for each section, some are in charge of large areas, other lymph nodes only manage a small section) start putting their work hats on and stimulating production of more tcell buddies to join the fight. The tcells start marching through your blood to find and destroy the foreign intruders. Once the tcells find the vaccine substances broken down in pieces in your system, they latch on and cover the enemy. Basically, your tcells are trying to over-power and kill the substances. And because there is such a small amount of the virus in the vaccine, your normal tcell army has the ability to do it's job. Where as if, say, you had come in contact with your friend who had the chicken pox, the amount of virus that would enter your system is drastically larger...and your tcell army doesn't stand a chance against fighting the virus off (hence the need for a vaccine, because your body can't fight it or prevent it on it's own). And because our bodies are so dang smart and miraculous, while they were attacking the foreign virus, they learned from that, and, just like a video game, your tcells leveled up and got stronger against that specific virus. Once it fights off the initial introduction of the virus, the theory is that you can introduce the normal/environmental amount to your body, and your tcells should have no problem showing the virus the door. As for the remaining ingredients, like mercury, your body kills what it can, and absorbs what it uses to make your body work (water, nutrients, vitamins). That's where autism comes in. Our bodies have the ability to wash out toxins in our blood, so the mercury in vaccines is usually not a problem. However, we are not made from cookie cutters, and everybody reacts differently. When you give/get a vaccine, and for some reason you are different and your body does not wash out the mercury like it's supposed to, it will continue to build up. Yes, mercury is very poisonous. When many of children's blood tests came back with VERY high levels of mercury, off the charts even, and those children happen to have one thing in common-autism, you can't help but confess that we definitely do not know everything we need to know about how the immune system works. So I've shared only what I know ;)
What organ produces killer t cells and destroys invading cells in the body?
T cells are made in the red bone marrow but specialize into t cells outside the marrow in the thymus, hence the T in Tcells. two types of t cells are cytotoxic effector cells and helper t cells. think of cytotoxic t cells as the drunk guy in the bar that wants to fight everyone (and is a good fighter by the way) and the helper t cells are the friends who show him who to fight and provides him with the weapons to fight. CTC can attach to and destroy cells carrying antigens Helper T cells 1. present antigen to CE cells and plasma B cells to activate them into action and 2. produe powerful immune protein called cytokins which can stimulate the lymphocyte cell disvision.
