[Blood platelets: neuronal model in psychiatric disorders].

C Dreux, J M Launay

    L'Encephale
    |March 1, 1985
    PubMed
    Summary

    Blood platelets serve as a valuable model for bioaminergic neurons, aiding in understanding psychiatric diseases. This platelet model shows promise in classifying disorders and managing treatments for conditions like depression and schizophrenia.

    Area of Science:

    • Neuroscience
    • Biochemistry
    • Psychiatry

    Background:

    • Blood platelets share similarities with bioaminergic neurons, particularly in neurotransmitter metabolism.
    • These similarities may stem from a common embryonic origin.
    • Platelet function alterations are observed in various psychiatric and neurologic syndromes.

    Purpose of the Study:

    • To explore the utility of blood platelets as a model for bioaminergic neurons.
    • To investigate the role of platelets in psychiatric disorders and neuro-endocrinology.
    • To assess the potential of the platelet model in biological psychiatry.

    Main Methods:

    • Comparative analysis of platelet and neuronal functions.
    • Observation of platelet function changes in psychiatric conditions.
    • Evaluation of psychotropic drug effects on platelet activity.

    Main Results:

    • Platelets exhibit similarities to neurons in serotonin metabolism and other neurotransmitters.
    • Changes in platelet functions (uptake, storage, enzymatic activity) correlate with psychiatric syndromes.
    • Psychotropic drugs impact platelet functions, supporting the model's relevance.

    Conclusions:

    • The blood platelet model is useful for classifying psychiatric diseases and managing treatments.
    • Platelets offer a potential model for studying neuro-endocrine disorders in psychiatry.
    • Methodological challenges currently limit the full development of the platelet model.
