Randomized trial investigates myeloid heparanase's role in insulin resistance and inflammation in type 1 diabetes, suggesting a therapeutic target.

This research aims to understand the role of myeloid-specific heparanase in type 1 diabetes and its impact on the immune response.
Integrated single-cell RNA sequencing data from human and mouse islets
Utilized genetic mouse models to assess the function of heparanase
Pharmacological intervention with muparfostat to evaluate therapeutic potential.
Myeloid-specific heparanase deficiency improved glucose tolerance and reduced inflammation in diabetic models.
Increased heparanase led to barrier degradation and amplified macrophage polarization via bioactive fragments.
Pharmacological inhibition of heparanase preserved the HS barrier and improved glucose homeostasis.
