The HIV viral cell attaches itself to a T-cell in a lock and key fashion. It specifically targets these cells. Once it attaches itself, it begins the process of entering the cell until it reaches the nucleus of the T-cell. There is goes about converting the genetic structure of the T-cell until eventually, a new HIV cells is produced. In most cases, the T-cell dies in the process.
This process is produced millions of times over. This is why it is said that the HIV virus destroys the immune system.

Why aids is not cause by mosquito?
Because HIV needs human immune cells to reproduce and does not survive in an insect.
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 kind of host does a virus need to reproduce?
Viruses need any kind of cell. Some have "favorites" like white blood cells (HIV).
Does HIV destroy T-cells?
With the T-cell lymphocyte, HIV basically disarms it and renders it unable to react to infection. Over time, this causes the number of T-cells to drop very low, rendering the person very susceptible to otherwise nominal bacterial, viral and fungal infections.
Does the blood cells in a syringe have to be alive to get HIV?
Time and amount blood in a syringe from an infected person determines how long HIV virus is still active. Infected blood exposed to air, once dried had died (becomes inert) and is no longer infectious. In a Syringe the life of active HIV cells will die (depending on how much blood is in the syringe) will take from one to four weeks. It is best to always dispose of a used syringe immediately. For HIV (or an infectious agent) to remain active, it needs host cells to reproduce. In a laboratory for instance, a synthetic agent or actual blood cells are kept in a controlled environment so it may be studied. HIV active cells will die almost as soon as blood leaves the body when exposed to air till it dries.
What cell does Aids attack?
AIDS (Acquired Immune Deficiency Syndrome) does not infect any cells of the body. AIDS is a diagnosis given to HIV+ patients when the exhibit certain clinical criteria. HIV (Human Immunodeficiency Virus) is the virus that causes AIDS. HIV attacks the part of the body that fights disease, the cells associate with immune function. Over time, as HIV infection progresses, an HIV+ person is less able to fight disease.
Can HIV cells be found in plants?
HIV cells are not found in plants. Forms of the HIV virus only exist in Primates and Felines.
How human immunodeficiency virus (hiv) affects on the immune system?
It uses one of the main type of immune cells - CD4 cells - to reproduce. The immune response to infection is to produce more CD4 cells, which the virus uses to reproduce even more etc. The immune system initially controls the virus. However, without treatment, usually over many years, the virus slowly wears down the number of CD4 cells. This leaves someone vulnerable to a wide range of serious infections.
How does AIDS cause a particular disease?
The virus that causes AIDS is called HIV. This virus uses one of the main type of immune cells - CD4 cells - to reproduce. The immune response to infection is to produce more CD4 cells, which the virus uses to reproduce even more etc. The immune system initially controls the virus. However, without treatment, usually over many years, the virus slowly wears down the number of CD4 cells. This leaves someone vulnerable to a wide range of serious infections.
Where can you find the infection from a virus its not in my blood?
To replicate viruses enter host body cells and take them over. Different viruses target different body cells. For instance the common cold virus targets the nasal membrains, herpies attacks nerve cells and HIV attacks bood cells.
What type of cells does HIV attack and destroy?
HIV infects only the CD4 cells of the immune system, and it destroys lymphocytes.
Hiv destroys what special cells?
T-cells.
