Study with NHLI

What we do

The Inflammation Repair and Development (IRD) Section encompasses research in immunobiology of leukocytes, the blood cells that function as part of the body's immune system, integrated with investigation of developmental, environmental or medical factors that contribute to lung disease. We study diseases including asthma, chronic obstructive pulmonary disorder (COPD), cystic fibrosis, interstitial lung disease (ILD), respiratory infections and acute respiratory distress syndrome (ARDS). 

Why it is important

  1. Respiratory disease is a significant cause of mortality and morbidity worldwide, however effective treatments for many respiratory diseases are limited. At the same time certain medical interventions aimed at prolonging life, such as mechanical ventilation, can cause injury to the lungs which may lead to acute lung damage or long-term structural changes. Our section aims to identify new treatments to repair damaged lungs.
  2. A fundamental knowledge of the immunobiology of leukocytes is essential to understand how the body reacts to infection and injury. We investigate leukocyte development, from bone marrow, their recruitment, retention and recirculation through tissues and their role in maintenance of immune homeostasis within the lung as well as their contribution to host defence during infections.  

Impact of our research

Research by groups in our section has led to:

  1. A new sub-lingual (under the tongue) treatment for hayfever.
  2. Identified a novel class of drugs to reduce inflammation in chronic neutrophilic lung diseases such as COPD and severe asthma that are currently being developed for use in man.
  3. Pioneered tailored treatments for children with asthma by using age-appropriate in vivo models along with patient samples.
  4. Identified key proteins that are altered in in patients with idiopathic pulmonary fibrosis (IPF), these are currently being followed up in international clinical trials as potential treatment biomarkers.

Summary of current research

Our section's research encompasses two main areas:

Events & meetings

  • Through the monthly IRD seminar series leading experts in the fields of inflammation, repair and development from around the UK and beyond present their work to the department. They also spend the day in the department, meeting the students, postdocs and Principal Investigators.

Public Engagement

As a section we are actively involved in public engagement activities for the department and Professor Sara Rankin is NHLI's Divisional Lead for Outreach.

We have recently received funding from the Wellcome Trust for a new project called Breathing Together - details will follow once the project launches in 2017.

Previous projects include:
