Cross-Sectional asthma cohort

Overview

Das allergische Asthma bronchiale im Kindesalter wird als Fehlregulation des Immunsystems zugunsten eines pro-allergischen Th2-Phänotyps beschrieben. Das Th2/Th1-Ungleichgewicht könnte durch eine Fehlregulation der regulatorischen T-Zellen und möglicherweise auch in Interaktion mit den pro-inflammatorischen Th17-Zellen zustande kommen. Klinisch relevant ist neben dem allergischen jedoch auch der nicht-allergische Phänotyp. Der Schwerpunkt dieses Projekts liegt daher auf der Untersuchung der regulatorischen T- und Th17-Zellen in Interaktion mit Th1/Th2-Zellen bei Kindern mit allergischem und nicht-allergischem Asthma bronchiale.

Description : Allergic asthma in childhood is described as a dysregulation of the immune system in favor of a pro-allergic Th2 phenotype. The Th2/Th1-imbalance may be mediated by dysregulation of regulatory T cells and potentially also by interaction with pro-inflammatory Th17 cells. Both the allergic and non-allergic asthma phenotype are clinically relevant. The focus of this project is the investigation of regulatory T- and Th17 cells in interaction with Th1/Th2-cells in children with allergic and non-allergic asthma.
