Structure of HIV immunity mechanism destruction

To man or the animal, the immunity system is ready as introduced on the page of immunity. Some illnesses can prevent the infection after the second time now. (An immunity system is not realized with the virus which changes type like an influenza virus every year.)
Now, if a HIV virus goes into the inside of the body, it will change a form rapidly. And it will become in six - eight weeks that HIV follows and an antibody can do a helper T-lymph cell. At the time, the HIV virus is changing the form, and the antibody and virus which had done relation between a key and a keyhole are not connected, but are kept very much in infection.

Let's check this by a diagram.

Structure of immunity mechanism destruction (1) HIV enters.
(2) A macrophage eats a virus… HIV increases.
(3) HIV invades into a helper T-lymph cell using CD4 (duplicate key)…It follows and hides out and a gene is increased....The T-lymph cell which has not been infected carries out an antibody production command to B cell. Moreover, a virus repulse command is carried out to other T-lymph cells.
(4) It is not effective even if it makes an antibody since a form is changed rapidly, although B cell makes an antibody after six - eight weeks.
(5) The instructions from a helper T-lymph cell cannot mark weakly, and an antibody does not fit into a virus.
(6) What is tidied up since the antibody has not marked does not understand a killer T cell.
(7) A memory T-lymph cell cannot memorize a virus.

(8) HIV multiplication
