Type Ⅲ TGF-βreceptor mediated signaling pathway and its role in fibrotic diseases / 中国药理学通报

ABSTRACT

Transforming growth factor β(TGF-β)superfamily ligands play an important role in regulating cellular homeostasis including proliferation,differentiation,apoptosis,immune sur-veillance and angiogenesis.Type Ⅲ TGF-βreceptor (TβRⅢ) is considered to be the coreceptor of TGF-βsuperfamily.TβRⅢnot only has an effect on classical Smad signaling pathway,but also on non-Smad signaling pathway.TβRⅢplays a crucial role in fibrosis,tumor,cardiovascular diseases via mediating kinds of signaling pathways.This paper reviews TβRⅢ mediated sig-naling pathway and its role in fibrotic diseases.
