Does recycling in germinal centres exist?

abstract：:Human regulatory T cells (Tregs) expressing the transcription factor FoxP3 play indispensable roles for the maintenance of immunological self-tolerance and immune homeostasis. In this review, we discuss immunological characteristics of human FoxP3(+) Tregs and to what extent they are similar to or different from the m...
