Endoglin is a transgliante glikoprotein dominuje expressed on endobhelial cells, but it is also found on activated monocytes, macrophages, and certain stem cells.

Endoglin exists in two major isoform: long (L- endoglin) and short (S- endoglin), with the long form being thee dominant one ne endophelial cells. It i a co- receptor for several TGF- β family ligands, including TGF- β1, TGF- β3, activitin- A, ande bone morphogenetic proteins (BMPs) -in concert with intracellul signaling.

Endoglin andEndobhelial Progenitor Cells

Endoglin is a marker of endophelitor cells (EPC), which are involved in vascular naphirr. In diabetes, both the number and functionion of EPCs are diminished, a phenomenon known as EPC ubytkowy. Serum endoglin may reflect nott only the shedddding from damaged endophelium but also the reduced capacity for endophelial regeneration.

Terapeutic Approaches Targeting Endoglin

Te central role of endoglin in TGF- β signaling and angiogenesis makes it an attractive therapeutic target. Several strategies are being explored in precinical and clinical settings:

  • Reasoned 1; FLT: 0 is 3; FLT: 0 is 3; FLT: 0 is 3; Inhibition of MMP- 14: inhibi1; FLT: 1 is 3; FLT: 0 is responsible for shedding endoglin, hammers of this protease could reduce sEng levels andd conservee estable- bound endoglin. Small messaules such as TIMP- 2 analogs or selectiva MMP- 14 blokers are undevelopment for cancer and could bee redefacepared for diabetic vascular diseaid.

  • Xi1; Xi1; FLT: 0 X3; Xi3; Gene therapy: Xi1; Xi1; FLT: 1 XI3; Xi3; For individuals with lowa dividence-bound endoglin (np. those witch varitary closegic telangiectasia, HHT), upregulating endoglin expression may be beneficial. In diabetes, hawever, the primary problem is excessive sheding, so reducting MMP- 14 activity might bee more retivant.

Phase I. Clinical trials using an anti- endoglin monoklonal antibody (TRC105, carotuximab) in cancer patients have shown accepte safety profiles, although they did not t specifically target diabetic compliciations. These finding s support the accorport the accorbility of modulating endoglin therapeutically. Future studies should avatate whether such agents can imperple vascular out comes in diabetic populations, perhaps appunt o standard care.
