The serotonergic system dysfunction in diabetes mellitus

Area of Science:

• Neuroscience
• Endocrinology
• Pharmacology

Background:

• Serotonin (5-HT) is a key monoamine synthesized peripherally and stored in platelets.
• Central serotonin modulates mood and feeding behavior, with therapeutic efforts facing peripheral side effects.
• Emerging evidence links both peripheral and central serotonergic systems to diabetes.

Purpose of the Study:

• To review the multifaceted roles of the serotonergic system in diabetes.
• To examine its involvement in blood glucose regulation and diabetic complications.
• To assess its potential as a therapeutic target for diabetes treatment.

Main Methods:

• Literature review of studies on the serotonergic system and diabetes.
• Analysis of research on serotonin's role in glucose homeostasis.
• Synthesis of findings related to diabetic macroangiopathy, neuropathy, and encephalopathy.

Main Results:

• The serotonergic system significantly influences blood glucose regulation.
• Serotonin pathways are implicated in the development of diabetic macrovascular and neurological complications.
• Dysregulation of serotonin contributes to diabetic encephalopathy.

Conclusions:

• The serotonergic system is a critical factor in diabetes pathogenesis and progression.
• Targeting the serotonergic system offers promising therapeutic avenues for managing diabetes and its complications.
• Further research is warranted to fully elucidate and exploit the clinical significance of serotonin in diabetes care.
