Septin functions in organ system physiology and pathology

Area of Science:

• Molecular Biology
• Cell Biology
• Human Physiology

Background:

• Septins are a family of GTP-binding proteins that form filamentous polymers.
• They play crucial roles in cellular structure, membrane organization, and cytoskeleton dynamics.
• Over 30 human septin isoforms exist, with diverse expression patterns.

Purpose of the Study:

• To review the expression and function of septins in various human organ systems.
• To explore the link between septin tissue-specific functions and human diseases.
• To provide a comprehensive overview of septin involvement in human health and pathology.

Main Methods:

• Literature review of studies on septin expression and function.
• Analysis of research linking septin roles to specific organ systems.
• Synthesis of data on septin aberrations in human diseases.

Main Results:

• Septins are expressed ubiquitously and in tissue-specific patterns across cardiovascular, immune, nervous, urinary, digestive, respiratory, endocrine, reproductive, and integumentary systems.
• Septin functions are critical for the development and physiology of these organs.
• Aberrations in septin expression are associated with the pathology of numerous human diseases.

Conclusions:

• Septins are fundamental to the proper functioning of all major human organ systems.
• Understanding tissue-specific septin roles is key to deciphering their involvement in disease.
• Septin research offers potential therapeutic targets for a wide range of human pathologies.
