TGFB1
TGFB1 encodes transforming growth factor beta-1 (TGF-β1), a secreted cytokine and multifunctional signaling molecule in the transforming growth factor beta family.
TGFB1 encodes transforming growth factor beta-1 (TGF-β1), a secreted cytokine and multifunctional signaling molecule in the transforming growth factor beta family. It is a central regulator of cell growth, differentiation, extracellular matrix production, immune modulation, wound repair, and tissue remodeling. Through canonical Smad2/3 signaling and related non-canonical pathways, TGF-β1 can promote either homeostatic repair or pathological fibrosis depending on cellular context, dose, and disease state.
In biomedical research, TGFB1 is frequently studied as both a mechanistic driver and a therapeutic target. It is especially relevant in fibrosis, cancer progression, immune suppression, cartilage regeneration, diabetic wound healing, and transplant biology. In tumors, TGFB1 is often associated with immunosuppressive microenvironments and poor prognosis; in regenerative settings, it can support matrix deposition and lineage-specific differentiation, including chondrogenesis and wound repair.

Pulmonary Fibrosis Biology
Fibroblast activation and macrophage signaling are being connected to extracellular-matrix remodeling in pulmonary fibrosis. Bleomycin models implicate Atg5-dependent autophagy in myofibroblast accumulation and alveolar regeneration, while related fibroblast–macrophage work highlights thrombospondin-1 in fibroinflammatory niches. Therapeutic work is testing rearranged steroids and bispecific CHI3L1/PD-1 targeting. Whether these approaches reverse established fibrosis or mainly limit injury remains open.

TGF-β1 Injury Signaling
Small-molecule and herbal interventions are being evaluated to blunt TGF-β1/Smad-associated injury across diabetic and ocular tissues. Tanshinone IIA, salvianic acid A, salvianolic acid B and hydroxysafflor yellow A reduce cerebral injury, while fermented Astragalus is assessed in diabetic nephropathy. Selpercatinib adds a mechanistically distinct approach by suppressing TGF-β1-induced epithelial–mesenchymal transition in retinal pigment epithelium. The evidence remains preclinical and context-specific, with Smad2/3 signaling and tissue injury as recurring readouts.

Others — TGFB1-Linked Tissue Studies
Cardiac fibrosis, cartilage differentiation and allergic rhinitis are linked here mainly by TGFB1-related signaling, not by a shared disease context. Oleuropein is studied as a modulator of the TGF-β1/Smad pathway in diabetic cardiomyopathy. Separate biomaterial studies use HAMA hydrogels and bioprinting to guide periosteal-cell chondrogenesis, while EGR2 and TGFB1 are explored as allergic-rhinitis biomarkers. The set supports pathway-level investigation but offers no unified therapeutic direction.
