THE Hypothesis of Skin - Liver Communication in Early- life Fibrosis : The Role of Stellate Cells,Vitamin A, and oxygen prioritization

This article proposes a novel hypothesis regarding the developmental origins of liver fibrosis. It suggests that the high oxygen demand of the brain in early neonatal life prioritizes active red blood cells (RBCs), leading to their premature degradation and increased iron load on the liver. As a result, hepatic stellate cells (HSCs) may be activated too early—while they are still immature in their role of producing high-quality vitamin A—especially in the absence of a fully functional visual system. This premature activation might initiate a long-term fibrotic program. The hypothesis also integrates the role of skin signaling, micronutrients (vitamin D, magnesium), and growth signals during early development. This multifactorial model seeks to explain how miscommunication between skin, liver, and brain may set the stage for chronic liver fibrosis in adulthood. The hypothesis may offer a new pathway for preventive strategies such as vaccine-based approaches during developmental windows.
