Protects the body destroys bacteria and tumor cells?
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.
Why do people with AIDS fall victim to opportunistic infections?
HIV invades helper T cells, which then begin to produce HIV soon after their infected. As helper T cells die, the immune system gradually weakens and becomes overwhelmed by pathogens that it would normally detect and destroy.
Why do some cancer medications sometimes weaken the immune system of cancer patients?
The radiation kills bone marrow, where both red and white blood cells are made. The white blood cells produce most of the immune system, with fewer white blood cells the immune system weakens.
What are designer viruses used for?
this is used destroy cancer cells and leavethe good one unharmed
What do the different types of blood cells work together to produce the immune response?
Antigens! I have this exact question for health!
Explain how people with AIDS get illnesses that healthy people usually don't get?
HIV, the virus that leads to the disease of AIDS, infects cells in our immune system called T-Helper Cells. These cells have a protein on the surface called CD4, so T-Helper cells are also CD4+ cells. The main purpose of the CD4+ cell is to bind to protein pieces (epitopes) of bacteria and other pathogens that are presented to them by antigen-presenting cells (APCs). APCs includedendritic cells (DCs) and macrophages. When a CD4+ cell recognizes a pathogen, it releases lymphokines, which attract other immune cells to the area, enhancing the immune response (and ultimately causing inflammation). CD4+ cells also recognize antigens shown to them by B-Cells and release chemicals that cause the B-cells to form antibodies specific to that pathogen or invader. Once the antibodies are released, they bind to the pathogen, which allows phagocytes to bind to the invader and eventually kill it. Therefore, CD4+ cells are essential for a well-informed immune system and a healthy body. AIDS develops when enough HIV has infected and led to the death of CD4+ cells that less than 200 CD4+ cells per microliter of blood remain (healthy individuals have approximately 1000-1200 CD4+ cells per microliter). Without a good supply of CD4+ cells, an AIDS patient's immune system lacks the most effective method for recognizing pathogens/invaders that could easily be recognized and destroyed by a healthy person's immune system. Therefore, they develop diseases that healthy people never have to worry about.
What are facts about the immune system?
Laughing reduces stress cells which in turn strengthens your immune system not helping me out in need 4 facts not helping me out either I need 5 interesting facts about the immune system by tonight my project is due tomorrow
Why should youth stay away from drugs?
Because I believe their minds are still forming and learning so why destroy good brain cells?
What is primary liver carcinoma?
It is a good question! Liver is a common site for the secondary invasion of almost all type of cancers. But liver cells are not immune from getting converted into cancer cells. When this happens, it is called as primary liver carcinoma.
Can raising your Ph level above 7.5 help in the treament of cancer?
The theory that this concepts relies on is that by changing the Ph of the body, you will invariably destroy the cancer cells in the body. However, research has shown that th good cells can be just as sensitive to these changes in Ph levels. So if you attack the cancer cells, you will also be destroying the good cells in the body at the same time.
An important defense against diseases in vertebrate animals is the ability to eliminate inactivate or destroy foreign substances and organisms explain how the immune system achieves the following?
Provides an immediate nonspecific immune response I think this is talking about the physical barriers that stop a foreign substance from entering the body. Mucous, skin, hair... those are physical barriers that stop foreign substances from entering the body. Activates T and B cells in response to an infection There are two types of T cells, helper cells which help B cells, and Killer Cells which kill foreign substances. The T cells are activated when a phagocyte eats a foreign substance and takes it to the spleen to identify what the foreign substance is. The T cells make an antigen that binds to the foreign substance so the B cells can "kill" the foreign invader. Responds to a later exposure to the same infectious agent Sam process except it is more faster then previously. The immune system creates memory B cells that remember the foreign substance and it begins immune responses to fight off the infectious agent. Distinguishes self from non self It is all about the antigens. If the person has an antibody for a flu or something, it will fight that flu that has the antigen for the flu. If it has an antibody for something that is self that is called an autoimmune response which is not good at all.
What is B-cell?
it is a lymphocytes that plays a large role in humeral immune response. It also helps in making antibodies.
