Asymmetrical brain modulation of the immune response

Area of Science:

• Neuroimmunology
• Central Nervous System (CNS) and Immune System Interaction

Background:

• The central nervous system (CNS) regulates the immune system.
• Brain hemispheres exhibit differential roles in modulating immune responses.
• Evidence suggests lateralization in brain function influences immune parameters.

Purpose of the Study:

• To investigate the asymmetrical brain modulation of immune responses.
• To explore the correlation between lateralized motor behavior and immune system activity.
• To examine the bidirectional communication between the brain and immune system.

Main Methods:

• Lesion studies on rodent neocortex to assess immune parameter changes.
• Analysis of immune disorders in relation to handedness in humans.
• Correlation of paw preference in mice with immune cell activity and auto-antibody production.

Main Results:

• Neocortical lesions in rodents induced opposing effects on immune parameters.
• Left-handedness in humans is linked to a higher incidence of immune disorders.
• Paw preference in mice correlated with altered lymphocyte reactivity, natural killer cell activity, and auto-antibody production.

Conclusions:

• Brain asymmetry significantly influences immune system function.
• Immune system signals may be asymmetrically processed by the brain.
• Experimental models of neuroimmunomodulation are valuable for research.
