We use a translational biology "bench to bedside" approach to address research questions in pulmonary fibrosis and sarcoidosis.
Idiopathic pulmonary fibrosis
Idiopathic pulmonary fibrosis (IPF) is a progressive scarring disease affecting the lungs of older people. We believe that development of effective therapies in the future will depend on a clear understanding of what initiates and perpetuates lung scarring. We have discovered abnormalities of platelet function in patients with IPF. We are studying how the pulmonary vascular endothelium responds to injury and how these responses contribute to pulmonary fibrosis by promoting retention and activation of platelets in the lungs.
We are studying the potential use of novel imaging techniques in pulmonary fibrosis, both in the lab (in collaboration with Hull University Dept. of chemistry) and in the clinic.
We have an ongoing interest in assessing and treating symptoms in pulmonary fibrosis, particularly breathlessness and cough.
Sarcoidosis is an inflammatory disease of unknown cause. Whilst some cases remit spontaneously, there is no curative treatment. We are studying immune responses in the blood and lung tissue of patients with sarcoidosis to help understand how the disease is initiated and driven. We are particularly interested in how abnormal function of regulatory (inhibitory) receptors on blood monocytes leads to an overactive immune system in sarcoidosis.
