What is the role of macrophages in HIV infection?
What is the role of macrophages in HIV infection?
- They prevent the replication of HIV in the body
- They directly attack helper T-lymphocytes
- They help in the production of anti-retroviral drugs
- They act as a HIV factory by producing virus particles (correct)
How does HIV affect the number of helper T-lymphocytes in the body?
How does HIV affect the number of helper T-lymphocytes in the body?
- It causes an immediate increase in the number of helper T-lymphocytes
- It has no effect on the number of helper T-lymphocytes
- It leads to a progressive decrease in the number of helper T-lymphocytes (correct)
- It leads to a sudden fluctuation in the number of helper T-lymphocytes

Study Notes
HIV Infection and Immune System
- Macrophages, a type of white blood cell, play a role in HIV infection as they can be infected by HIV, allowing the virus to replicate and spread.
HIV and Helper T-Lymphocytes
- HIV targets and destroys helper T-lymphocytes (CD4 cells), which are crucial for fighting off infections, leading to a significant decline in their numbers.
Diagnosing AIDS
- The ELISA (Enzyme-Linked Immunosorbent Assay) and Western Blot tests are widely used to diagnose AIDS, detecting the presence of HIV antibodies in the blood.
Prevention of AIDS
- Prevention is considered the best option for AIDS, as there is no cure, and the virus can be transmitted through unprotected sex, contaminated needles, and from mother to child during pregnancy, childbirth, or breastfeeding.
Treating AIDS with Anti-Retroviral Drugs
- Anti-retroviral drugs can effectively slow down the progression of HIV infection to AIDS, reducing the viral load and increasing the CD4 cell count, thereby improving the quality of life for people living with HIV.
