    Serotonin immunoreacmtivitiyn the carotid body of adult humans
    (Murcia : F. Hernández, 1994) Habec, J.; Pallot, D.J.; Kummer, W.
    The distribution of serotonin immunoreactivity (-1R) was studied in adult human carotid bodies, obtained at post-mortem, using both the peroxidaseantiperoxidase method on paraffin sections and a doublelabelling immunofluorescence on frozen sections. Antibodies against synaptophysin and protein gene product (PGP) 9.5 were used for identification of serotonin-1R cells. Serotonin-1R was demonstrable in the carotid bodies of adult humans and it was coexpressed mostly with synaptophysin or PGP 9.5 in type 1 cells. Some serotonin immunopositive type I cells were located in close proximity to capillaries. Serotonin-IR was also observed in a few endothelial cells.
