SuPAR
suPAR, soluble urokinase-type plasminogen activator receptor, ( NCBI Accession no. AAK31795) is the soluble form of uPAR. uPAR is a membrane bound receptor for uPA, otherwise known as urokinase as well as Vitronectin. suPAR results from the cleavage and release of membrane-bound uPAR. suPAR concentration positively correlates to the activation level of the immune system and is present in plasma, urine, blood, serum, and cerebrospinal fluid. suPAR is a marker of disease severity and aggressiveness.
