The cells, which suppress the entire immune system from its attack in the same body, are known as

Options

A. Helper T-cells
B. Killer B-cells
C. Suppressoe cells
D. Suppressor T-cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the type of cells that suppress the immune system to prevent it from attacking the body's own cells. This is crucial for maintaining self-tolerance and preventing autoimmune diseases.

2. **Identifying the Relevant Cells**: The cells that play a significant role in preventing the immune system from attacking the body are known as suppressor cells. These cells help regulate the immune response.

3. **Focus on T Cells**: Among the various immune cells, T cells are particularly important. There are different types of T cells, including T helper cells, T killer cells, and T suppressor cells.

4. **Role of T Suppressor Cells**: T suppressor cells (also known as regulatory T cells) are specifically responsible for suppressing the activity of other immune cells, including T killer cells and B cells. This suppression is vital for preventing the immune system from attacking the body’s own tissues.

5. **Evaluating the Options**: The options provided include:
- A) Helper T cells
- B) Killer B cells
- C) Suppressor cells (general)
- D) Suppressor T cells

After evaluating these options, we can conclude:
- A) Helper T cells are involved in activating the immune response, not suppressing it.
- B) Killer B cells are not a recognized category in the immune system.
- C) Suppressor cells is too general and does not specify the type.
- D) Suppressor T cells are indeed the correct answer, as they specifically suppress the immune response.

6. **Final Answer**: The cells that suppress the entire immune system from attacking the same body are known as **suppressor T cells**.
