Treg领域的大牛Rudensky在四月的Ann Rev Immunol 关于Treg 分化和功能的最新review。尤其是对于Treg在胸腺和外周分化所需的TCR讯号和因子论述十分详细（老实说这一部分看的不是太懂）。
虽然没有正面回答，但这篇文章确实解答了本人心中几个疑问，例如Treg能否增殖（能），nTreg和iTreg有无不同（distinct）等。
希望大家一起学习。
Regulatory T cells: mechanisms of differentiation and function
Josefowicz SZ, Lu LF, Rudensky AY.
Abstract
The immune system has evolved to mount an effective defense against pathogens and to minimize deleterious immune-mediated inflammation caused by commensal microorganisms, immune responses against self and environmental antigens, and metabolic inflammatory disorders. Regulatory T (Treg) cell-mediated suppression serves as a vital mechanism of negative regulation of immune-mediated inflammation and features prominently in autoimmune and autoinflammatory disorders, allergy, acute and chronic infections, cancer, and metabolic inflammation. The discovery that Foxp3 is the transcription factor that specifies the Treg cell lineage facilitated recent progress in understanding the biology of regulatory T cells. In this review, we discuss cellular and molecular mechanisms in the differentiation and function of these cells.
