Connective tissue: a body-wide signaling network?

Area of Science:

• Anatomy
• Physiology
• Biophysics

Background:

• Loose connective tissue forms a pervasive anatomical network.
• Its role as a signaling network is not widely recognized.

Purpose of the Study:

• To propose and explore the hypothesis that connective tissue functions as a body-wide mechanosensitive signaling network.
• To identify potential signaling mechanisms and their implications for health and disease.

Main Methods:

• Theoretical review and hypothesis formulation.
• Discussion of proposed signaling categories: electrical, cellular, and tissue remodeling.
• Consideration of mechanical force influence on signaling pathways.

Main Results:

• Connective tissue signaling is hypothesized to involve dynamic patterns of electrical, cellular, and remodeling signals.
• These signals are proposed to be responsive to mechanical forces over various timescales.
• Signaling patterns may be influenced by movement, posture, and pathological conditions.

Conclusions:

• Connective tissue may function as a previously unrecognized whole-body communication system.
• This signaling network could influence and be influenced by the function of multiple organ systems.
• Demonstrating this network could significantly advance understanding of health and disease.
