Red cell deformability: physiological, clinical and pharmacological aspects.

G A Marcel

    Journal of Medicine
    |January 1, 1979
    PubMed
    Summary

    Red blood cell deformability is crucial for survival, as cells must navigate narrow capillaries. Impaired red blood cell filterability is being investigated for clinical and therapeutic implications.

    Area of Science:

    • Hematology
    • Physiology
    • Medical Research

    Background:

    • The human circulatory system contains approximately 25 trillion red blood cells (RBCs).
    • RBCs travel through an extensive capillary network spanning 300 miles.
    • RBCs have a diameter of 7-8 microns, while capillaries measure 3-5 microns.

    Purpose of the Study:

    • To investigate the clinical implications of red blood cell (RBC) deformability.
    • To explore potential therapeutic consequences related to RBC filterability.

    Main Methods:

    • A French task force involving 40 University Hospitals is conducting the investigation.
    • The study focuses on assessing red blood cell filterability.

    Main Results:

    • Red blood cell deformability is essential for survival due to the size difference between RBCs and capillaries.
    • Impaired RBC deformability is observed in various clinical conditions.

    Conclusions:

    • Understanding RBC deformability is critical for diagnosing and managing certain diseases.
    • Further research may lead to novel therapeutic strategies targeting RBC function.
