Why do DPP-4 inhibitors show neuroprotective effects but increase heart failure risk through sympathetic activation?

OPEN

The abstract reveals that DPP-4 inhibitors reduce Alzheimer's pathology yet worsen cardiovascular outcomes via increased sympathetic activity. This mechanistic contradiction within the heart-brain axis is unexplained and critical for therapeutic decision-making in diabetic patients. Gap type: contradiction Source paper: Interactions between antidiabetes medications and heart-brain axis. (2025, Current opinion in endocrinology, diabetes, and obesity, PMID:39639832)
