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.
Immunity uses helper cells and killer cells to identify and destroy abnormal cells?
Helper cells (e.g. T helper cells) play a role in activating the immune response by coordinating and stimulating other immune cells like killer cells (e.g. cytotoxic T cells) to target and destroy abnormal cells. Killer cells directly eliminate infected or abnormal cells by inducing programmed cell death. This coordinated effort helps the immune system effectively rid the body of threats.
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.
Hiv does the greatest damage to what?
HIV primarily targets the immune system, specifically the CD4 cells, also known as T-helper cells. By depleting the body's CD4 cells, HIV weakens the immune system, making it harder for the body to fight off infections and diseases. This can lead to the development of AIDS if left untreated.
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 is the body system that contains cells and organs that fight disease called?
That would be the vascular system.
What does HIV target the production of?
helper T cells
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.
When the human body mobilizes its defenses against a pathogen the body recognizes the?
antigen. Helper B and T cells most likely.
Helper or suppressor cells are types of?
A T cell that reduces, or suppresses, the immune response of B cells, or of other T cells, to an antigen.Wikipedia: regulatory T cellRegulatory T cells (sometimes known as suppressor T cells) are a specialized subpopulation of T cells that act to suppress activation of the immune system and thereby maintain immune system homeostasis and tolerance to self-antigens. The existence of a dedicated population of supressive T cells was the subject of significant controversy among immunologists for many years. However, recent advances in the molecular characterization of this cell population have firmly established their existence and their critical role in the vertebrate immune system. Interest in regulatory T cells has been heightened by evidence from experimental mouse models demonstrating that the immunosuppressive potential of these cells can be harnessed therapeutically to treat autoimmune diseases and facilitate transplantation tolerance or specifically eliminated to potentiate cancer immunotherapy.
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.
