Investigating the effects of IL-5 on asthma and immune responses

Non-Eosinophilic Biological Effects of Interleukin 5 (IL-5) - Role of IL-5 in Suppressing Anti-Viral Immunity in Bronchial Epithelial Cells and Dendritic Cells in Asthma

Observational Imperial College London · NCT06026202

This study is trying to see how a substance called IL-5 affects asthma and the immune system in people with asthma, especially during viral infections, and whether treatments that lower IL-5 can help improve their immune response.

What this trial studies

This observational study aims to explore the role of interleukin 5 (IL-5) in modulating immune responses in individuals with asthma. It focuses on how IL-5 may suppress anti-viral immunity in bronchial epithelial cells and peripheral blood mononuclear cells, particularly during viral infections. The study will assess whether elevated IL-5 levels correlate with reduced interferon production, which is known to help mitigate asthma exacerbations. Additionally, the research will evaluate the impact of anti-IL-5 therapies on IL-5 levels and their potential to restore anti-viral immunity in asthma patients.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with stable eosinophilic asthma who are eligible for the MAELABA study.

Not a fit: Patients with non-eosinophilic asthma or those not eligible for the MAELABA study may not benefit from this research.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of asthma exacerbations related to viral infections.

How similar studies have performed: While the specific approach of this study is novel, existing research has indicated the importance of IL-5 in asthma, suggesting potential for meaningful insights.
