A study from the Department of Medicine, Cedars-Sinai Medical Center, Los Angeles, California, USA; and Women’s Guild Lung Institute, Cedars-Sinai Medical Center, Los Angeles, California, USA shows that: “Hyaluronan and TLR4 promote surfactant-protein-C-positive alveolar progenitor cell renewal and prevent severe pulmonary fibrosis in mice.” This study was published in the 03 October 2016 issue of the journal “Nature Medicine” by Prof. Noble PW, Liang J and others.
On the foundation of this interesting finding, Dr L Boominathan PhD, Director-cum-chief Scientist of GBMD, reports that: Natural product therapy for Pulmonary Fibrosis: Onion Peel extract (OPE) increases Toll-like receptor 4 expression and extracellular matrix glycosaminoglycan Hyaluronan levels, promotes alveolar progenitor cell renewal and repair of lung injury and prevents severe pulmonary fibrosis via down-regulation of its target gene
Given that: (1) Pulmonary disease (PD)/Pulmonary fibrosis (PF) is a progressive degenerative disease of the lung, with debilitating consequences; (2) drugs that are currently used to treat PF are ineffective; (3) molecular mechanisms involved in the development of pulmonary fibrosis is poorly understood; (4) 6.8-16.3 per 100,000 persons suffer from Idiopathic pulmonary disease; and (5) 5 million people worldwide are affected by Pulmonary fibrosis (PF), there is an urgent need to find: (i) a way to regenerate alveolar epithelial cells lost in pulmonary fibrosis patients; (ii) a side-effect-free natural product-based drug; and (iii) a way to effectively treat and cure PF.
Prof. Noble’s research team has recently shown that deletion of TLR4 or HA synthase 2 results in pulmonary fibrosis.
Figure1: Onion peel extract inhibits the progression of pulmonary fibrosis via up-regulation of TLR4 and Has2
This study suggests, for the first time, that Onion Peel extract (OPE), by decreasing the expression of its target gene, it may increase the expression of TLR4 and HA synthase 2 (HAS2). Thereby, it may: (1) increase extracellular matrix glycosaminoglycan Hyaluronan on cell surface; (2) promote alveolar progenitor/stem cell renewal; (3) promote repair of lung injury; and (4) inhibit the development and progression of pulmonary fibrosis. Thus, pharmacological formulations encompassing “Onion Peel extract (OPE) or an active component isolated from it” may be used to regenerate alveoloar epithelial stem cells and treat pulmonary fibrosis.
