Human immunodeficiency virus parasitizes which of the following cells?
- Correct answerA$\text{T}_4$ lymphocytes
- BB Lymphocytes
- CMemory B Cells
- DKiller T Cells
Solution
Human Immunodeficiency Virus (HIV) specifically targets and parasitizes helper T cells in the human immune system.
Helper T cells are also known as $\text{T}_4$ lymphocytes or CD4+ T cells because they possess CD4 receptors on their surface. The virus uses these receptors to attach to and enter the host cell.
By infecting and subsequently destroying these $\text{T}_4$ lymphocytes, HIV progressively weakens the immune system, which can eventually lead to Acquired Immunodeficiency Syndrome (AIDS).
