Calcium and the aging nervous system.

G E Gibson, C Peterson

    Neurobiology of Aging
    |July 1, 1987

    Summary
    This summary is machine-generated.

    Aging impairs calcium regulation, affecting cell functions and potentially leading to neurological disorders. Restoring calcium levels may improve age-related deficits in brain function and behavior.

    Area of Science:

    • Gerontology
    • Cellular Physiology
    • Neuroscience

    Background:

    • Calcium homeostasis is critical for cellular function.
    • Aging significantly alters calcium regulation across various cellular compartments.
    • Understanding these age-related calcium changes is crucial for addressing neurological decline.

    Purpose of the Study:

    • To investigate the fundamental changes in calcium regulation during aging.
    • To explore the link between altered calcium ion movement and age-related functional deficits.
    • To identify potential therapeutic targets for age-related neurological disorders.

    Main Methods:

    • Analysis of age-related changes in calcium permeation across membranes.
    • Investigation of calcium mobilization from intracellular organelles.

  • Assessment of calcium-dependent biochemical and neurophysiological processes in aging models.

    • Main Results:

    • Age-related decreases in calcium permeation and organelle mobilization are fundamental changes.
    • Deficits in calcium ion movement disrupt calcium-dependent processes, impacting neurophysiology.
    • Increased calcium availability can ameliorate age-related deficits in neurotransmission and behavior.

    Conclusions:

    • Age-related alterations in calcium homeostasis, particularly reduced ion movement, contribute to cellular dysfunction.
    • These calcium dysregulations may predispose the brain to neurological disorders.
    • Targeting calcium homeostasis represents a promising therapeutic strategy for age-related conditions.
