Different Activity of the Biological Axis VEGF-Flt-1 (<i>fms</i>-Like Tyrosine Kinase 1) and CXC Chemokines between Pulmonary Sarcoidosis and Idiopathic Pulmonary Fibrosis: A Bronchoalveolar Lavage Study

Abstract

Our data suggest that increased expression of Flt-1 and downregulation of CXCL12 alpha in IPF may further support the hypothesis of a different angiogenetic profile between fibrotic and granulomatous diseases. However, further studies are needed in order to better investigate these enigmatic diseases.
