Chronic lung allograft dysfunction, the major cause of death following lung transplantation, usually manifests as irreversible airflow obstruction associated with obliterative bronchiolitis (OB), a lesion characterized by chronic inflammation, lymphoid neogenesis, fibroproliferation and small airway
The role of platelet-derived growth factor (PDGF) in the development of obliterative bronchiolitis (OB) as a manifestation of chronic rejection was investigated in the heterotopic rat tracheal allograft model. An increase in intragraft PDGF-Ralpha and -Rbeta mRNA expression, and in PDGF-AA and
OBJECTIVE
Development of anti-HLA antibodies is associated with development of bronchiolitis obliterans syndrome after lung transplantation. We sought to determine the mechanism by which anti-HLA antibodies affect the development of bronchiolitis obliterans syndrome. We postulated that anti-HLA
BACKGROUND
The main cause of morbidity and mortality after lung transplantation (LT) is bronchiolitis obliterans syndrome (BOS). Anti-HLA antibodies development after LT has been shown to play an important role in BOS pathogenesis. However, the nature of non-HLA antibodies developed after LT and
Bronchiolitis obliterans (BO) is a progressive and fatal disease after lung transplantation (LTX). Dysregulated growth factor-induced proliferation of myofibroblasts seems to be responsible for the development of BO. The aim was to confirm the efficacy of both inhibitors of receptor tyrosine kinases
Interstitial lung disease is a well-known pulmonary adverse event that occurs during epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy and results in restrictive ventilatory dysfunction. However, obstructive changes such as those associated with bronchiolitis obliterans
BACKGROUND
Cytomegalovirus (CMV) infection is a risk factor for the development of obliterative bronchiolitis (OB) after lung transplantation.
METHODS
In the rat tracheal allograft model, rat CMV (RCMV) infection is associated with accelerated OB through enhanced alloimmune activation and increased
Obliterative bronchiolitis (OB), a fibrotic airway lesion, is the leading cause of death after lung transplantation. Type V collagen [col(V)] overexpression and IL-17-mediated anti-col(V) immunity are key contributors to OB pathogenesis. Here, we report a previously undefined role of IL-17 in
BACKGROUND
Imatinib, a tyrosine kinase inhibitor, has been proposed as a potential anti-fibrotic agent for fibroproliferative diseases, including bronchiolitis obliterans (BO). However, the underlying anti-fibrotic mechanisms of the agent remain unclear. We evaluated whether bone (BM)-derived
BACKGROUND
A rare but serious complication of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) therapy is a lung injury syndrome commonly referred to as a drug-induced interstitial lung disease (ILD). It has a typical clinical presentation of rapidly progressive acute or
BACKGROUND
Platelet-derived growth factor (PDGF) is an important smooth muscle cell mitogen, and vascular endothelial growth factor (VEGF) is a known angiogenic and proinflammatory growth factor. We hypothesized that specific therapy aimed at these growth factors might inhibit the development of
Chronic lung allograft dysfunction (CLAD) still remains a major drawback in the outcome following lung transplantation (LTx). New therapeutic strategies are warranted. Growth factors and their receptors like platelet-derived growth factor-receptor (PDGFR) and vascular endothelial growth
Pulmonary toxicity is a known complication of erlotinib, one of the epidermal growth factor receptor tyrosine kinase inhibitors. It consists of diverse entities such as interstitial pneumonitis, bronchiolitis obliterans with organizing pneumonia and pulmonary fibrosis. In our report, an unusual case
