Which cells continue to produce virus and act like a HIV factory?

Options

A. Tc cells
B. CTL
C. B - Lymphocytes
D. Macrophages

Answer

To answer the question: "Which cells continue to produce virus and act like a HIV factory?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding HIV and AIDS**:
- HIV stands for Human Immunodeficiency Virus, which causes AIDS (Acquired Immunodeficiency Syndrome). It primarily targets the immune system, specifically certain types of white blood cells.

2. **Identifying Key Cells Affected by HIV**:
- The main cells that HIV infects are T helper cells (also known as CD4+ T cells). These cells are crucial for the immune response and help activate other immune cells.

3. **Analyzing the Options**:
- **T Cells (T helper cells)**: These are the primary targets of HIV. When infected, they can produce more virus, effectively turning into factories for HIV replication.
- **Cytotoxic T Lymphocytes (CTL)**: These cells are involved in killing infected cells but are not the primary targets of HIV.
- **B Lymphocytes**: While they play a role in the immune response, they are not the main cells that HIV uses to replicate.
- **Macrophages**: These cells help engulf pathogens but are not the primary cells that HIV replicates in.

4. **Conclusion**:
- The correct answer is **T helper cells**. These cells continue to produce the virus and act like an HIV factory.

### Final Answer:
The cells that continue to produce virus and act like an HIV factory are **T helper cells**.
