CD4 cells are a subtype of T cells, which are produced in the thymus gland and regulate the immune system's response to infected or malignant cells.

What sends word to killer T cells and actavaite B cells?
Helper (CD4+) T Cells
What human cell is attacked by HIV?
The Human Immunodeficiency Virus (HIV) seems to only infect the CD4 (or T-helper) cells of the immune system. The CD4 cells are responsible for activating and directing other immune system cells. HIV also infects macrophages and microglial cells that express the CD4 molecule on their surface. The virus can also infect a subtype of myeloid dendritic cells MDC-1.
Which test measures the number of helper T cells in the bloodstream of patients with AIDS?
A CD4 test
How is HIV different from other virus pathogens?
HIV is a retro virus, that infects your immune cells. The virus attaches to CD4 receptors on T-cell (the cells that are part of the immune system.)
Is a CD4 molecule also a type of antigen?
CD4 is a glycoprotien expressed on the surface of Helper T Cell
How many CD4 T cells do we have?
500 cells/mm3 to 1,000 cells/mm3 CD4 T cells
What does HIV target the production of?
helper T cells
Which cells are destroyed in an aids infection?
HIV attacks and kills CD4 helper T cells.
Can my CD4 count increase without mediction?
That is unlikely, since the HIV virus directly attacks the CD4 cells. In time, the virus will destroy all CD4 cells. Without medications, that will happen sooner rather than later.
Can lupus drop your CD-4 count?
CD4 cells are T helper cells that help fight infection. Yes, lupus can cause a drop in your CD4 count.
What a low cd4 cell count?
Presumably, a lower-than-normal number of CD4+ T lymphocytes in your blood. CD4+ T cells are required for a healthy immune system.
How is HIV and Helper T Cells related?
T helper cells, also called CD4+ T cells (or just CD4 cells) are part of the immune system, but they are also the main target cells that HIV infects and uses to reproduce.
What does the viral load and CD4 count indicate?
The viral load is a measure of how much HIV is present in the blood. A high viral load count would indicate the person has many copies of the virus in their body. The CD4 count, on the other hand, indicates how many CD4 or T-helper cells the person has. CD4 cells are part of the immune system. When they are destroyed, their numbers drop. This is what the HIV virus does--it destroys CD4 cells. Therefore, if a person has a low CD4 count, that means that their immune system is not functioning well, if at all.
Where can one purchase cd4 cells?
CD4 cells cannot be purchased as they are a cell that is within the body. They are part of the immune system and help fight infections and disease within the body.
What sends word to killer T cells and actavaite B cells?
Helper (CD4+) T Cells
What is the function of CD4?
CD4 is a surface receptor expressed by helper T lymphocytes, known as CD4+ T cells. Its purpose is to stablize the interaction between the T cell receptor (on the T cell) and an antigen-bearing MHC Class II molecule (on an antigen presenting cell). Under the right circumstances, this interaction activates CD4+ T cells that recognize an invading pathogen. Activated CD4+ T cells do many things, and are required for a robust adaptive immune response.
What is the significance of a CD4 count?
The CD4 count is a test that determines the amount of white blood cells in the body. It is used to figure out the progression of HIV and AIDS. The white blood cells fight infection.
