Leukocyte Trafficking

Ed Group 2019 - 1

Group leaders: Professor Ed Rainger, Dr Helen McGettrick, Dr Asif Iqbal and Dr Myriam Chimen


Our research aims to understand the mechanisms that regulate recruitment of leukocytes into inflamed tissues during protective resolving responses, and how these processes go wrong in chronic inflammatory and auto-immune diseases.  We have described new pathways which regulate migration of leukocytes into tissue through the endothelial cells which line blood vessels, and the roles of local flow and of the surrounding tissue in defining normal or pathological inflammatory responses.

Our research group

The Group Leads work in a highly collaborative manner with over-lapping projects, using in vitro and in vivo models for studying a variety of factors that influence leukocyte trafficking. In vitro models of the vasculature allow us to visualise the effects of blood flow on the behaviour of endothelial cells, and on the recruitment of leukocytes, platelets and stem cells. We have also developed sophisticated co-culture models to examine how platelets, monocytes or stromal cells (e.g. fibroblasts, mesenchymal stem cells) regulate the delivery of leukocytes to foci of disease. More recently, we have extended this concept using integrated 3-D multi-cellular models which allow us to track leukocytes through layers of primary human cells and determine their behaviour and ultimately their fate. To complement this work we use transgenic and preclinical models of disease, along with intravital microscopy, to further dissect these processes in vivo and elucidate mechanisms and potential therapeutic targets.

Platelets and inflammation

  • Do platelets exacerbate the atherogenic process by regulating the recruitment, differentiation and inflammatory function of monocytes (British Heart Foundation Programme Grant)
  • Characterisation of blood-borne microvesicles in patients suffering trauma and investigation of their influence on inflammatory and thrombotic responses (NIHR Surgical Reconstruction and Microbiology Research Centre)
  • The role of platelet derived microvesicles in regulating the differentiation and inflammatory function of foam cells (British Heart Foundation PhD Studentship).

Role of adiponectin-PEPITEM axis in health and disease

  • Characterising the endothelial cell receptor for PEPITEM, a novel peptide that regulates T cell trafficking during inflammation (Medical Research Council Confidence in Concept Grant)
  • Defining the therapeutic potential of a PEPITEM in RA (Pfizer)
  • Demonstrating the utility of the adiponectin-PEPITEM axis as biomarker to detect RA in very early pre-symptomatic patients (Enterprise Birmingham Fund)
