E M Silverman, A G Silverman

    American Journal of Clinical Pathology
    |January 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Older adults exhibit increased granulocyte adherence, a key immune cell function. This finding highlights age-related immune system changes, with alcohol impacting adherence in the elderly.

    Area of Science:

    • Immunology
    • Gerontology
    • Hematology

    Background:

    • Age-related changes in immune cell function are not fully understood.
    • Granulocyte adherence plays a role in immune response and inflammation.

    Purpose of the Study:

    • To investigate age-related differences in granulocyte adherence.
    • To examine the effect of common medications and alcohol on granulocyte adherence in older adults.

    Main Methods:

    • Blood samples were collected from individuals aged 11-59 and over 60 years.
    • Granulocyte adherence was measured and compared between age groups.
    • The influence of specific medications and recent alcohol consumption was assessed.

    Main Results:

    Related Experiment Videos

  • Older subjects (over 60) demonstrated significantly higher granulocyte adherence (78.4%) compared to younger subjects (65.7%).
  • Hemoglobin, leukocyte, and neutrophil counts were lower in the older group.
  • Alcohol ingestion within 24 hours was linked to reduced granulocyte adherence in older individuals. Medications tested had no significant effect.

    • Conclusions:

    • Granulocyte adherence increases with age, contrasting with decreased leukocyte and neutrophil counts.
    • Alcohol consumption may negatively impact granulocyte adherence in the elderly.
    • Sex differences in granulocyte adherence persist into advanced age.
