Detailed explanation-1: -HIV binds to the CD4 molecule on the surface of helper T-cells and replicates within them. This results in destruction of CD4+ T-cells and leads to a steady decline in this population of T-cells.
Detailed explanation-2: -HIV finds the white blood cells, called CD4 cells. HIV gets inside the CD4 cell and makes copies of itself. Then, HIV kills the CD4 cell and the new HIV copies find other CD4 cells to get inside and start the cycle again. HIV kills immune system cells that help the body fight infections and diseases.
Detailed explanation-3: -HIV attacks a specific type of immune system cell in the body. It’s known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections.
Detailed explanation-4: -HIV-1 primarily targets and infects the CD4+ T helper cells, macrophages, and dendritic cells in humans.
Detailed explanation-5: -HIV destroys CD4 T lymphocytes (helper T cells). Because of this, healthcare professionals measure CD4 levels to monitor HIV progression and AIDS. Helper T cells are crucial for immune system function and activate after encountering antigens from disease-causing microorganisms.
