Transforming growth factor-beta1 and major trauma: time-dependent association with hepatic and renal insufficiency.

Dysbalance in the immune system is perceived as a major factor for adverse outcome after trauma. Transforming growth factor-beta1 (TGF-beta1) is a multifunctional cytokine that regulates proliferation, differentiation of cells, wound healing, and angiogenesis. The influence of TGF-beta1 on trauma patients outcome is still unclear.
