Question

why HIV attack only to T-Helper cells​

Answer 1

Answer:HIV attacks and kills crucial immune system cells, known as T-helper cells. Without T-helper cells (which kill cells that have been infected with germs) many other immune system cells cannot not work properly, including B-cells that make antibodies. A person infected with HIV may not show any symptoms for years. But untreated, the number of T-helper cells steadily drops. Eventually, the numbers fall so low that the risk of infection greatly increases, and the symptoms of AIDS appear.

Answer 2

Answer:

Human Immunodeficiency Virus (HIV) specifically attacks Helper T cells. Without an adequate supply of Helper T cells, the immune system cannot signal B cells to produce antibodies or Cytotoxic T cells to kill infected cells.

Explanation:

HIV infects a type of white blood cell in the body's immune system called a T-helper cell (also called a CD4 cell). These vital cells keep us healthy by fighting off infections and diseases. HIV cannot grow or reproduce on its own. Instead, the virus attaches itself to a T-helper cell and fuses with it.  When HIV destroys this cell, it becomes harder for the body to fight off other infections. HIV destroys CD4 cells by using their replication machinery to create new copies of the virus.
