The extracellular spaces are protected by the humoral immune response, in which antibodies produced by B cells cause the destruction of extracellular microorganisms and prevent the spread of intracellular infections. This is often called antibody mediated immunity. This response is triggered by an antigen and usually requires helper T cells.

What part of the body is affected by HIV-?
The HIV affects the immune system cells called the T-helper cells.
Why would your body need a specific defense system if you already have a non-specific defense system?
Because most of the time, your non-specific defense system (i.e. skin & white blood cells [phagocytes]) are not enough to fight off disease, so your more specialized cells (Helper T, B, antibodies, and Killer T cells) are usually needed.
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.
What occurs within the t4 cell?
T4 cells, also known as CD4 or helper T cells, protect the immune system in the body from infection. These cells release cytokines into the blood stream as a defense against antigens from viruses.
What does HIV target the production of?
helper T cells
What is the body system that contains cells and organs that fight disease called?
That would be the vascular system.
When the human body mobilizes its defenses against a pathogen the body recognizes the?
antigen. Helper B and T cells most likely.
How can you use nerve cells in a sentence?
Nerve cells are a part of the nervous system. There are nerve cells all around the body. Without nerve cells your body would not function the way it does.
How does the digestive system help body cells?
how dose the digestive system help body cells
Why is the body's response to HIV described as war?
Because your immune system is literally at war with the virus that invaded it. It's a good analogy because it accurately describes what is happening. The "invading" HIV virus goes on the attack and target specific blood cells called CD4 or T-helper cells. CD4 cells are crucial to your body's defense system. If they are compromised or destroyed, the body is left unable to protect itself from disease.
Which body system would be directly affected if lots of T cells were destroyed by a virus?
Immune system
What is the role of T cells in a human body?
T cells are part of the adaptive immunity. There are two major types of T cells: CD4+ T helper cells and CD8+ T cytotoxic cells. T helper cells primarily function in humoral immunity whereas T cytotoxic cells are important in cell mediated immunity. T helper cells produce cytokines to activate other immune system components like macrophages, B cells, etc. whereas T cytotoxic cells primarily kill infected cells.
