The cells that actually release the antibodies are

Options

A. Helper T-cells
B. Cytotoxic T-cells
C. Plasma cells
D. Memory cells

Answer

To answer the question, "The cells that actually release the antibodies are," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Antibodies**: Antibodies are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.

2. **Identify the Types of Immune Cells**: The immune system consists of various types of cells, including helper T cells, cytotoxic T cells, plasma cells, and memory cells.

3. **Differentiate Between Cell-Mediated and Humoral Immunity**:
- **Cell-Mediated Immunity**: This involves T cells (like helper T cells and cytotoxic T cells) and does not directly involve antibodies.
- **Humoral Immunity**: This involves B cells, which are responsible for producing antibodies.

4. **Focus on B Cells**: B cells are a type of lymphocyte that plays a crucial role in the humoral immune response. When activated, B cells can differentiate into two types of cells: plasma cells and memory cells.

5. **Identify the Function of Plasma Cells**: Plasma cells are the differentiated form of B cells that specifically produce and secrete antibodies into the bloodstream.

6. **Conclusion**: Based on the above information, the cells that actually release antibodies are the plasma cells.

### Final Answer:
The cells that actually release the antibodies are **plasma cells**.
