Clinical and experimental evidence suggests the central nervous system modulates immune functions.
Brain immunomodulation may exhibit lateralization, influencing immune responses differently based on brain hemisphere.
Existing research highlights a connection between brain asymmetry and immune system regulation.
Purpose:
To investigate the lateralized nature of brain immunomodulation.
To explore the mechanisms of brain-immune system communication.
To assess the relevance of brain asymmetry in neuroimmunomodulation for understanding immune disorders.
Summary:
Unilateral ablation of the brain cortex in rodents revealed lateralized effects on immune cells; left cortex lesions depressed lymphocyte and macrophage functions, while right cortex lesions had no effect or enhanced them.
Behavioral studies in humans and animals suggest a link between lateralized behaviors (e.g., left-handedness) and immune system reactivity, further supporting brain asymmetry in neuroimmunomodulation.
These findings establish a potential animal model for studying immune perturbations, such as those observed in stroke, and highlight the significance of brain asymmetry in neuroimmunomodulation.
Impact:
Provides a novel animal model for studying brain-immune system communication and immune dysregulation post-stroke.
Suggests that brain asymmetry plays a crucial role in neuroimmunomodulation, impacting both theoretical understanding and clinical considerations.
Opens new avenues for research into the neurological underpinnings of immune disorders and potential therapeutic strategies.
