The Respiratory Medicine Division has research interests in granulocyte cell biology and trafficking, the genetic and molecular basis of pulmonary hypertension, the structure and function of alph1-antitrypsin and related serpins, the immunopathology of allergic diseases, phagosome maturation and bacterial killing, and the molecular mechanisms of ER stress and ubiquitination.

Edwin Chilvers, Professor of Respiratory Medicine and Alison Condliffe’s, University Lecturer in Respiratory Medicine, interests relate to granulocyte cell biology, in particular, the mechanisms underlying neutrophil priming, activation and apoptosis. The group also has an interest in P13-kinase and hypoxia signalling, neutrophil and eosinophil trafficking in vivo and primary immunodeficiency.

Nick Morrell, BHF Professor of Cardiopulmonary Medicine, is studying novel approaches to the treatment of pulmonary arterial hypertension (PAH). In particular, his laboratory has elucidated the ways in which mutations in the bone morphogenetic protein type II receptor (BMPR-II), which underlie the majority (80%) of familial PAH and 20% of idiopathic PAH, cause disease. The lab is identifying further rare genetic variation underlying PAH.

Stefan Marciniak, MRC Senior Clinical Fellow, is interested in the cell biology of protein folding within the endoplasmic reticulum and how failure of this process manifests as disease. This is relevant to malignancy, hypoxia and conformational diseases such as alpha1-antitrypsin.

Andres Floto, Professor of Respiratory Cell Biology, works on the molecular basis of phagocytosis and phagosomal function, how these processes influence the host responses to bacterial and mycobacterial infection, and how cell-autonomous immunity can be therapeutically enhanced. The group is also utilising population-level whole genome sequencing to understand the epidemiology and pathophysiology of non-tuberculous mycobacteria.

James Nathan, Wellcome Trust Senior Clinical Fellow, studies the regulation of the ubiquitin proteasome system in disease and in particular, how different cellular proteins are efficiently targeted for degradation. The group also has an interest in the regulation of hypoxic response by ubiquitination.
