"Infected cell can survive while viruses are being replicated and released". In case of HIV infection given statement is true for which cell ?

Options

A. Macrophage
B. T-helper
C. T-killer
D. B-lymphocyte

Answer

To solve the question "Infected cell can survive while viruses are being replicated and released". In case of HIV infection, given statement is true for which cell, we will analyze the options provided.

### Step-by-Step Solution:

1. **Understanding HIV Infection**:
- HIV (Human Immunodeficiency Virus) primarily targets the immune system, specifically the CD4+ T helper cells. These cells are crucial for the immune response.

2. **Analyzing the Options**:
- **Option 1: Macrophages**:
- Macrophages are immune cells that engulf pathogens and secrete cytokines. While they can be infected by HIV, they do not survive long-term while actively replicating the virus. They eventually die after a short period.
- **Option 2: T Helper Cells**:
- T helper cells are indeed the primary target of HIV. The virus attaches to these cells, integrates into their DNA, and replicates. Importantly, these cells can survive for a time while the virus replicates and is released, making this option a strong candidate.
- **Option 3: T Killer Cells**:
- T killer cells (or cytotoxic T cells) are involved in killing infected cells and cancer cells. They are not the primary target of HIV and do not survive while replicating the virus.
- **Option 4: B Lymphocytes**:
- B lymphocytes are responsible for antibody production. They are not directly infected by HIV in the same way as T helper cells and do not fit the description of cells that survive while replicating the virus.

3. **Conclusion**:
- Based on the analysis, the correct answer is **T Helper Cells** (Option 2). These cells can survive while HIV replicates and is released.
