The PGI2 Pathway to Improve Healing of Diabetic Foot Ulcers

This study explored the role of the prostacyclin (PGI2) pathway in diabetic foot ulcers (DFUs), a complication of diabetes with high morbidity. Researchers hypothesized that dysfunction in the PGI2 pathway contributes to DFUs and could be a therapeutic target. Using diabetic mouse models, they investigated PGI2 pathway alterations through skin microvascular reactivity assays, receptor activation studies, and gene/protein expression analysis. The study found changes in PGI2 gene and protein expression in diabetic mice but did not find evidence of PGI2-dependent vasomotor dysfunction. The research suggested that laser speckle contrast imaging is a suitable model for monitoring wound healing in diabetic conditions.
