Which WBC increase in Allergy `:-`

Options

A. Acidophil
B. Basophil
C. Lymphocyte
D. Neutrophil

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which type of white blood cell (WBC) increases during an allergic reaction.

2. **Identifying the Options**: The options provided are:
- Acidophil
- Basophil
- Lymphocytes
- Neutrophil

3. **Analyzing Each Option**:
- **Acidophil (Eosinophil)**: These cells are primarily involved in combating parasitic infections and are not directly related to allergic reactions.
- **Basophil**: These WBCs play a significant role in allergic reactions. When an allergen enters the body, it triggers the production of IgE antibodies, which bind to basophils. This binding causes basophils to release histamine, leading to allergy symptoms.
- **Lymphocytes**: These cells are involved in the immune response, with B lymphocytes responsible for antibody production and T lymphocytes for cell-mediated immunity. They are not specifically increased in allergic reactions.
- **Neutrophil**: These are phagocytic cells that help in fighting infections but are not primarily involved in allergic responses.

4. **Conclusion**: The WBC that increases in response to allergies is the **Basophil**.

5. **Final Answer**: Basophil
