Research Article: Sputum Neurturin Levels in Adult Asthmatic Subjects
Abstract:
Neurturin (NRTN) is a member of the glial cell line-derived neurotrophic factor (GDNF) family of ligands (GFLs). GDNF is a protein structurally related to transforming growth factor (TGF)-? and mediates signals through the glycosyl-phosphatidylinositol (GPI)-anchored coreceptors (GFR?-), which acts as a ligand binding component., The neurotrophic factors, comprising GDNF, NRTN, artemin and persephin, are well known for their implication in the growth and survival of the various nerve systems. Due to its ability to control functions in neutral cells, NRTN has been assessed in clinical trials as a treatment for neurodegenerative diseases such as Parkinson’s disease., Moreover, exogenous NRTN rescues neurons in models of Parkinson’s disease, as well as in Hirschsprung disease. It has also been reported that the GDNF, NRTN, and their predominant receptors (GFR? and GFR?) mRNA are expressed during embryogenesis, most notably in epithelial–mesenchymal interactions. GDNF and NRTN play critical roles in the outgrowth of epithelial structures. In recent years, accumulating evidence suggests that the neuronal and immune systems exhibit bidirectional interactions that play critical roles in tissue homeostasis and inflammation (neuro-immune crosstalk). GFLs are expressed during inflammation outside the nerve system in peripheral tissues. In addition to their role as a nerve growth factor, GFLs have also been suggested to be involved in inflammation.
