Autophagy orchestrates the crosstalk between cells and organs

Area of Science:

• Cell Biology
• Molecular Biology
• Physiology

Background:

• Cell-to-cell and organ-to-organ communication are vital for understanding health and disease.
• Autophagy is essential for cellular functions and homeostasis.
• Autophagy plays a key role in mediating cellular and systemic processes through secretion.

Purpose of the Study:

• To review the emerging role of the autophagy-derived secretome in intercellular and inter-organ communication.
• To discuss the mechanisms by which the autophagy-derived secretome influences physiological and pathological states.

Main Methods:

• Literature review of studies on autophagy and extracellular communication.
• Analysis of the components and functions of the autophagy-derived secretome.
• Discussion of the implications of autophagy-derived secretome in various biological contexts.

Main Results:

• Autophagy secretes diverse cargo, including nutrients, proteins, mitochondria, and extracellular vesicles.
• This secreted cargo acts as a signaling mechanism, influencing cell fate, tissue microenvironment, and systemic physiology.
• The autophagy-derived secretome mediates metabolic, inflammatory, and structural adaptations in both health and disease.

Conclusions:

• The autophagy-derived secretome is a critical mediator of communication between cells and organs.
• Understanding this pathway is crucial for comprehending homeostasis and developing therapeutic strategies for diseases.
