Connection and communication between the nervous and immune systems

Area of Science:

• Neuroimmunology
• Physiology
• Systems Biology

Background:

• The nervous and immune systems, once viewed separately, are now understood as interconnected for brain-body physiology.
• Bidirectional communication between these systems is crucial for detecting and responding to diverse stimuli.

Purpose of the Study:

• To review the collaborative mechanisms between the nervous and immune systems.
• To examine how this integrated network responds to internal and external stressors.

Main Methods:

• Review of existing literature on neuro-immune interactions.
• Analysis of immune-nervous communication through spatial (brain, peripheral organs, distance) and temporal (development, distribution, function) frameworks.

Main Results:

• The nervous and immune systems share a common architecture and vocabulary for communication.
• Nervous system influence impacts immune cell development, distribution, and function throughout the lifespan.
• Integrated responses to psychological stress, circadian cues, infection, and tissue injury are mediated by neuro-immune crosstalk.

Conclusions:

• The nervous and immune systems operate as an integrated network, not in isolation.
• Understanding neuro-immune interactions is key to comprehending responses to somatic and environmental stressors.
• Future research should focus on tools, clinical applications, and unanswered questions in neuro-immune coordination.
