the virus doesn’t affect the T cell at all

Detailed explanation-1: -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-2: -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-3: -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.
Detailed explanation-4: -This is because HIV hides from the body’s immune system in a group of immune cells called CD4 lymphocytes, also known as the HIV reservoir. While HIV is latent in the reservoir, meaning it doesn’t replicate, it can wake up, causing viral load to increase and making a cure elusive.
Detailed explanation-5: -The HIV virus destroys part of the immune system, specifically a type of white blood cell called a T lymphocyte or T cell (or CD4 helper lymphocyte cell, or CD4 cell.
