Regulated cells
T regulatory cells are a component of the immune system that suppress immune responses of other cells. This is an important "self-check" built into the immune system to prevent excessive reactions. Regulatory T cells come in many forms with the most well-understood being those that express CD4, CD25, and FOXP3 (CD4 CD25 regulatory T cells). These Treg cells are different from helper T cells. Another regulatory T cell subset is Treg17 cells. Regulatory T cells are involved in …
