Final answer:
Regulatory T cells (Treg) are responsible for inhibiting inflammation by suppressing other immune cell responses, which helps maintain immune tolerance and prevent autoimmune diseases. The correct option is 4) TREG
Step-by-step explanation:
The type of T helper cell that inhibits inflammation is the regulatory T cell (Treg). Regulatory T cells are critical for maintaining immune tolerance and preventing autoimmune diseases by suppressing the immune responses of other cells. This is a crucial function as unchecked immune responses can lead to detrimental autoimmune conditions.
The unique markers of Treg cells include CD4, CD25, and the transcription factor FOXP3. Understanding the role of Treg cells is essential since they regulate the immune system and ensure it doesn't attack the body's own tissues. The correct option is 4) TREG
