Fig. 2From: BDNF/TrkB axis activation promotes epithelial–mesenchymal transition in idiopathic pulmonary fibrosisK252a by BDNF/TrkB axis modulate the mesenchymal and epithelial markers in fibroblast cell line. Representative immunofluorescence pictures showing that BDNF binding to TrKB receptor up-regulates the expression of mesenchymal markers. These effects are inhibited by the specific TrkB receptor selective inhibitor K252aBack to article page
