Abstract
Here we present an assessment of the HCII-T biomarker in mouse models of MPS I, IIIA and IIIB, which suggests that HCII-T is a reliable marker for MPS I when measured in serum or dried blood spots stored for over a year at 4 °C, but that murine MPS IIIA and IIIB cannot be reliably detected using this biomarker. We also show that HCII-T formation in vivo is dependent on the presence of excess intravenous dermatan sulphate (DS), whilst intravenous heparan sulphate (HS), does not promote complex formation effectively. This suggests that HCII-T will prove effective as a biomarker for MPS I, II, VI and VII diseases, storing dermatan sulphate but may not be as appropriate for MPS III, storing heparan sulphate. With careful sample preparation, HCII-T ELISA could prove to be a useful biomarker for both newborn screening and measurement of treatment outcomes in selected MPS diseases.
