Expression of T-bet and its regulation on CD4(+) T cell polarization in aplastic anemia / 中国实验血液学杂志

ABSTRACT

Aplastic anemia (AA) is an autoimmune disease which take hematopoietic tissue as target cells. T lymphocyte-mediated cellular immune abnormality plays a key role in the pathogenesis of AA. Increase and hyperfunction of Thl lymphocytes are main feature of AA disease. The recent studies indicated that T-bet is Th1 cell-specific transcription factor, is crucial factor for polarization of CD4(+) T lymphocytes to Th1. High expression of T-bet in AA patients is an important link in pathogenesis of AA. In this article, T-bet and its relation with AA, including expression of T-bet in AA patients, the regulation of T-bet on polarization of CD4(+) T lymphocytes are reviewed.
