Protein Kinases Signaling in Pancreatic Beta-cells Death and Type 2 Diabetes

Area of Science:

• Endocrinology
• Cell Biology
• Metabolic Disease Research

Background:

• Type 2 diabetes (T2D) is a global health crisis driven by insulin resistance and beta-cell dysfunction.
• Glucolipotoxicity-induced endoplasmic reticulum (ER) stress and inflammation contribute to the vicious cycle of T2D pathology.
• Overnutrition and activated protein kinase pathways are implicated as primary factors in T2D development.

Purpose of the Study:

• To review critical checkpoints influencing beta-cell fate in T2D.
• To explore the role of protein kinases in T2D pathogenesis.
• To discuss therapeutic strategies for preserving beta-cell viability.

Main Methods:

• Literature review and synthesis of current research on T2D mechanisms.
• Analysis of factors affecting beta-cell function and survival, including ER stress, oxidative stress, and inflammation.
• Examination of protein kinase signaling pathways relevant to T2D.

Main Results:

• Hyperglycemia, unfolded protein accumulation, reactive oxygen species (ROS), and saturated fatty acids induce beta-cell failure and apoptosis.
• Mitophagy dysfunction, inflammation, and insulin resistance exacerbate T2D.
• Beta-cell dedifferentiation is observed in T2D, impacting insulin secretion.

Conclusions:

• Protein kinase signaling pathways are crucial in regulating beta-cell fate and function in T2D.
• Targeting these pathways offers potential therapeutic avenues for T2D treatment.
• Further clinical trials are necessary to validate novel therapeutic strategies for T2D.
