Patients with BMS were shown to represent a heterogeneous group in terms of inflammatory biomarkers.

The results furthermore indicate that reduced sialylation of MUC7, particularly Si-Le(x), may be an important feature in patients with BMS. However, the functional aspects and potential involvement in immune regulation of Si-Le(x) remains unclear. Our data suggests a chemokine driven alteration of MUC7 glycosylation.
