Playing contract bridge increased CD4-positive T lymphocytes in healthy women. This finding may relate to immune-incompetent mice showing reduced frontal cortex thickness, which thymic transplants can reverse.

Area of Science:

  • Neuroscience
  • Immunology
  • Cognitive Psychology

Background:

  • The dorsolateral frontal cortex plays a role in cognitive functions.
  • Immune system deficiencies can impact neurological health.

Purpose of the Study:

  • To investigate the effect of cognitive stimulation on immune cell counts.
  • To explore the relationship between frontal cortex integrity and immune function.

Main Methods:

  • 12 healthy adult females played contract bridge for 1.5 hours.
  • Blood samples were analyzed using flow cytometry to count CD4-positive T lymphocytes.
  • Cortical thickness was measured in immune-incompetent mice.

Main Results:

  • A significant increase in CD4-positive T lymphocytes was observed after playing bridge.

  • Immune-incompetent mice exhibited reduced dorsolateral frontal cortical thickness.
  • Thymic transplants in mice reversed both cortical thinning and low CD4-positive cell counts.

    • Conclusions:

    • Cognitive engagement, like playing bridge, may positively influence immune cell populations.
    • Frontal cortex health is linked to immune competence, as suggested by mouse models.
    • Further research is warranted to understand the neuro-immune interactions.
