Transforming Growth Factor Beta Receptor Pathway (TGFβ Receptor Pathway)

The transforming growth factor beta (TGFβ) receptor pathway is a highly conserved signaling cascade that regulates a wide array of cellular processes in both developing embryos and adult organisms. These processes include cell growth, differentiation, migration, apoptosis, and maintenance of cellular homeostasis. The pathway also plays critical roles in immune regulation, vascular system function, tissue repair, and embryonic development. Overexpression or dysregulation of this pathway has been implicated in fibrosis across multiple organs including kidney disease, cancer progression/metastasis, and immune disorders due to altered regulatory/suppressive functions. Therapeutic targeting using antagonists against specific components has shown promise for reversing fibrosis or modulating immune responses.
