The complexes formed during immune complex mediated hypersensitivity are removed by:

Options

A. Eosinophils and T-cells
B. Monocytes and B-cells
C. Eosinophils and monocytes
D. Eosinophils and basophils

Answer

To solve the question regarding the removal of immune complexes formed during immune complex-mediated hypersensitivity, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Immune Complexes**: Immune complexes are formed when antibodies bind to antigens. This binding can lead to inflammatory responses in the body, which is characteristic of immune complex-mediated hypersensitivity.

2. **Role of Antibodies**: Antibodies, also known as immunoglobulins, are produced by B cells and are crucial for binding to antigens. They have a Y-shaped structure that consists of four polypeptide chains (two heavy chains and two light chains).

3. **Inflammatory Response**: The formation of immune complexes can trigger inflammatory responses, which necessitate the removal of these complexes from the body to prevent damage.

4. **Cells Involved in Removal**:
- **Eosinophils**: These cells are involved in allergic reactions and can help eliminate immune complexes.
- **Monocytes**: These are phagocytic cells that can engulf pathogens but are not primarily responsible for removing immune complexes.
- **T Cells**: Specifically, cytotoxic T cells can also assist in the removal of immune complexes.

5. **Evaluating the Options**:
- **Option 1 (Eosinophil and T cell)**: This option includes both eosinophils, which help in hypersensitivity reactions, and T cells, which can assist in the removal of immune complexes. This option is likely correct.
- **Option 2 (Monocyte and B cell)**: Monocytes are not primarily involved in removing immune complexes, and B cells produce antibodies but do not directly remove complexes.
- **Option 3 (Eosinophil and Monocyte)**: While eosinophils are involved, monocytes do not play a significant role in removing immune complexes.
- **Option 4 (Eosinophil and Basophil)**: Eosinophils are involved, but basophils are primarily involved in allergic responses and do not assist in the removal of immune complexes.

6. **Conclusion**: The correct answer is **Eosinophil and T cell**, as both of these cell types play significant roles in the removal of immune complexes formed during immune complex-mediated hypersensitivity.

### Final Answer:
The complexes formed during immune complex-mediated hypersensitivity are removed by **Eosinophils and T cells**.
