Helper T-cells are white blood cells. Most white blood cells kill or "hijack" infected host cells as they fight disease and infection. Unlike other white blood cells Helper T-cells do not have a capability to kill or take over the infected host cells, so their contribution in fighting disease and infection is by activating and directing the proper white blood cells to the infected host cell which needs killing or "hijacking".
I think comparing it to a GPS system in your automobile would make it simpler. While you may know WHERE you are supposed to go, the GPS shows activates and gives you directions. most any of the GPS's will "Activate" or "alert" you by speaking aloud and then giving directions "Turn Right ahead" or "Proceed ahead for 1 mile and turn left onto..." thus activating you how and where to drive the car to get to the proper destination.

What do t cells do?
(t-cells) are involved in cell mediated immunity that can have memory of previous antigens(non self) that have invaded our body. cytotoxic tcells release preforin that destroy tumor cells or antigens helper tcells release cytokines/interlukins that help in more tcell differentiation
Immunity uses helper cells and killer cells to identify and destroy abnormal cells?
Cellular immunity uses helper cells and killer cells to identify and destroy abnormal cells.
What cell is the most critical cell in immunity?
helper T cell
How do you use the word helper in a sentence?
I hired a mother's helper to assist me with my twin boys. Julie often volunteered as a helper for her teacher.
Which of the following cells is the most critical cell in immunity?
Helper T cell
What is another word for assist?
Helped, aided, backed, supported.
What is responsible for cell-mediated immunity?
In cell mediated immunity the lymphocytes go and attack the offending microorganism. This develops after about 2 to 3 weeks after the first attack by microorganisms.
What is a synonym for aide?
Help or support:assistance, helper, auxilary help
What are the differences between humoral immunity and cellular immunity?
ANTIBODY IMMUNITY IS BETTER TERMED AS HUMORAL IMMUNITY Humoral immunity is acquired by B-lymphocytes and T-helper lymphocytes as An antigen is engulfed by antigen processing cell (APC) e.g. , B-cells then a part of an antigen (epitope) is presented to T-helper cells in association with MHC-II (MAJOR HISTOCOMPATIBILITY COMPLEX) then T-helper cell activates B-cell to produce effector cell (plasma cell) and memory cell then plasma cell secrete antibodies which neglify harmful or toxic effects of the above antigen. CELL MEDIATED IMMUNITY Every cell of the body can show this response while in the above case only APC can show humoral response A whole foreign body/ antibody is engulfed by the cell then epitope is represented to cytotoxic T-lymphocytes(CTLs) then CTLs secrete certain chemicals which kill the cell along with foreign body.
What is produced by T cells?
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 does humoral immunity involves?
The cells which are involved in the production of antibodies are known as B cells. These are effector cells which will secrete anybodies and activate the antigens.
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.
