Baicalin, a natural compound, promotes regulatory T cell differentiation

BACKGROUND CD4(+)CD25(+)Foxp3(+) regulatory T (T(reg)) cells inhibit autoimmunity and protect against tissue injury. The development of these T(reg) cells is controlled by the regulator protein Foxp3, which can be enhanced by the in vitro activation of Foxp3 in the presence of transforming growth factor-beta. However, little is known about alternative methods, such as the use of natural product...

Identification of Baicalin as an Immunoregulatory Compound by Controlling TH17 Cell Differentiation

T(H)17 cells have been implicated in a growing list of inflammatory disorders. Antagonism of T(H)17 cells can be used for the treatment of inflammatory injury. Currently, very little is known about the natural compound controlling the differentiation of T(H)17 cells. Here, we showed that Baicalin, a compound isolated from a Chinese herb, inhibited T(H)17 cell differentiation both in vitro and i...

Transcriptional control of regulatory T-cell differentiation.

Regulatory T (Treg) cells are essential for maintaining peripheral tolerance and for limiting excessive inflammatory responses under various conditions. The lineage-specific transcription factor Foxp3 has a critical role in Treg-cell biology. Foxp3 forms large protein complexes and cooperates with environmentally induced transcription factors to shape the Treg-cell transcriptional program. Here...

Liver X receptor activation promotes differentiation of regulatory T cells

The nuclear receptor Liver X Receptor (LXR) is a ligand-activated transcription factor that has been implicated in control of chronic inflammation by downregulating pro-inflammatory T cell responses. An impaired function of regulatory T cells, a subset of CD4+ T cells with a crucial role in maintaining lymphocytes homeostasis and immune regulation, is frequently observed in chronic inflammatory...
