The biomarker suPAR (soluble urokinase-type plasminogen activator receptor), discovered in 1992, is the soluble form of the cell membrane-bound protein uPAR, which is expressed primarily in immune cells, endothelial cells and smooth muscle cells. uPAR is released in inflammatory or activation processes of the immune system, therefore, in these situations, suPAR reflects the degree of immune activation in the subject [1].
