Disease Activity Biomarkers in Patients With Systemic Lupus Erythematosus (JD001)

June 29, 2022 updated by: Cliniques universitaires Saint-Luc- Université Catholique de Louvain

Disease Activity Biomarkers in Patients With Systemic Lupus Erythematosus. Recherche de Biomarqueurs de l'activité de la Maladie Chez Des Patients Atteints de Lupus érythémateux disséminé.

The aim of this research project is to better understand the origin and clinical significance of two lupus-specific "genetic signatures" (IFN signature and plasma cell signature) in patient subgroups with well-defined clinical characteristics. Our aim is to correlate these genetic signatures with cell activation profiles and the production of specific cytokines in different populations from whole blood and in short-term cultures of these circulating cells.

Detailed Description

The aim of the experiment is, on the one hand, to identify and study the different cell populations from whole blood by flow cytometry and, on the other hand, to assay different cytokines in blood and urine samples from diseased (SLE) and control subjects (with non-inflammatory rheumatic diseases) in order to highlight and correlate the presence of biomarkers to disease activity or to a clinical manifestation of the disease.

In vitro studies will also be carried out on short-term cultures of PBMCs (Peripheral Blood Mononuclear Cells).
