Abstract
Recent studies have associated the dysregulated expression of Annexin-A1/Formyl peptide receptor 2 (FPR2/ALX) system with the development of autoimmune diseases. In this study we systematically scanned human leukocyte subsets for the presence of this pathway aiming to provide a roadmap that will help investigators to explore possible links between the development of immune related disorders and the expression of this system. Our results show that neutrophils, monocytes and NK cells express higher levels of both AnxA1 and FPR2/ALX compared to T or B cells. Further analysis of specific T cell subsets revealed higher levels in activated CD25(+) and memory CD45RO CD4 T cells compared to resting CD25(-) or naïve CD45RA CD4 T cells. Together the results expand our knowledge of the AnxA1-FPR2/ALX system in immune cells and provide new avenues for investigation into the functions of this signalling pathway in systems other than that classically described for neutrophils.
