Molecular Mechanisms and Targeted Therapies of PTPN2 in Metabolic Diseases: A Review

Area of Science:

• Biochemistry
• Immunology
• Endocrinology

Background:

• Metabolic disorders are a growing global health concern.
• Protein tyrosine phosphatase non-receptor type 2 (PTPN2) is crucial for regulating cellular signaling and metabolic homeostasis.
• PTPN2 influences immune responses, cell proliferation, and metabolic pathways, impacting conditions like diabetes and liver disease.

Purpose of the Study:

• To systematically review the molecular mechanisms of PTPN2 in various metabolic pathologies.
• To examine PTPN2's role in type 1 diabetes, type 2 diabetes, diabetic complications, and metabolic dysfunction-associated steatohepatitis.
• To highlight PTPN2-targeted interventions and their translational prospects for precision medicine.

Main Methods:

• Systematic literature review and synthesis of existing research on PTPN2.
• Analysis of PTPN2's molecular functions in cellular signaling and metabolic regulation.
• Evaluation of preclinical and clinical studies on PTPN2-targeted therapies.

Main Results:

• PTPN2 is implicated in the pathogenesis of multiple metabolic diseases, including diabetes and non-alcoholic steatohepatitis.
• PTPN2 modulates insulin sensitivity, glucose and lipid metabolism, and immune tolerance.
• Emerging PTPN2-targeted interventions show promise, particularly for type 2 diabetes.

Conclusions:

• PTPN2 is a critical regulator of metabolic health and a potential therapeutic target for metabolic disorders.
• Understanding PTPN2's context-dependent functions is essential for developing effective precision medicine strategies.
• Further research and clinical evaluation are needed to translate PTPN2-targeted interventions into effective treatments.
