Neurotrophic effects on the vascular bed.

B Folkow

    Acta Medica Scandinavica. Supplementum
    |January 1, 1983
    PubMed
    Summary

    Neurotrophic influences are crucial for the development of the vascular bed, especially in early growth phases. While local interactions between neurons and smooth muscle cells are vital, intrinsic cell adaptation mechanisms appear dominant in vivo.

    Area of Science:

    • Neuroscience
    • Vascular Biology
    • Cell Biology

    Background:

    • Neurotrophic factors play a significant role in the somatomotor system.
    • Understanding sympathetic neurotrophic effects on the vascular bed is an area of active research.

    Purpose of the Study:

    • To discuss current research on sympathetic neurotrophic effects on the vascular bed.
    • To differentiate between local trophic influences and intrinsic effector cell adaptation.

    Main Methods:

    • Review of tissue-culture studies on neurotrophic influences.
    • Analysis of in vivo experiments investigating neurotrophic effects on vascular beds.

    Main Results:

    • Tissue-culture studies highlight the importance of local trophic interactions between adrenergic neurons and vascular smooth muscle cells during early development.
    • In vivo studies suggest that long-term adaptation processes within effector cells are dominant, particularly under sustained activation.

    Conclusions:

    • Sympathetic neurotrophic influences appear to modulate and facilitate intrinsic cell adaptation mechanisms in the vascular bed.
    • The precise contribution of neurotrophic factors versus intrinsic adaptation in vivo remains challenging to quantify.
