Proteome and transcriptome analyses indicated that epithelial cell-derived heat shock protein-60 (HSP60) is the main mediator of BT effects on fibroblasts. Further analysis suggested that HSP60 regulated PRMT1 expression, which was responsible for the increased mitochondrial mass and α-smooth muscle actin expression by asthmatic fibroblasts. These effects were ablated after BT. These results imply that BT reduces fibroblast remodelling through modifying the function of epithelial cells, especially by reducing HSP60 secretion and subsequent signalling pathways that regulate PRMT1 expression.We therefore hypothesise that BT decreases airway remodelling by blocking epithelium-derived HSP60 secretion and PRMT1 in fibroblasts.Bronchial thermoplasty reduces asthma-associated airway wall remodelling by epithelial cell-controlled downregulation of PRMT1 expression in fibroblasts http://bit.ly/2TLhCkC}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/54/6/1900300}, eprint = {//www.qdcxjkg.com/content/54/6/1900300.full.pdf}, journal = {European Respiratory Journal} }
