Which cells are primarily targeted and infected by HIV?
Answer Choices:
Correct Answer:
CD4-positive T cells
Rationale:
🔴CD4-positive T cells are the primary target of HIV because they play a central role in immune regulation.
🔴HIV uses gp120 proteins to bind to CD4 receptors, enabling viral entry and replication inside the host cell.
🔴Destruction of these cells impairs both humoral and cell-mediated immunity, leaving the host vulnerable to infection.
🔴Monitoring CD4+ counts is critical in HIV management to assess immune function and guide antiretroviral therapy.
🔴Preservation of CD4+ cells is the main therapeutic goal to delay disease progression.
