  • Title: Selective uptake and retrograde axonal transport of dopamine-beta-hydroxylase antibodies in peripheral adrenergic neurons.
    Author: Fillenz M, Gagnon C, Stoeckel K, Thoenen H.
    Journal: Brain Res; 1976 Sep 17; 114(2):293-303. PubMed ID: 61057.
    Abstract:
    In the present experiments the uptake and retrograde axonal transport of antibodies to dopamine beta-hydroxylase (DBH) in adrenergic neurons was studied. When partially purified labelled antibodies to DBH were injected unilaterally into the vicinity of the adrenergic nerve terminals in the iris, radioactive substances accumulated preferentially in the superior cervical ganglia of the injected. By SDS (sodium dodecyl sulfate) gel electrophoresis and immunoprecipitation it could be shown that the accumulated radioactivity in the superior cervical ganglion represented antibodies to DBH. This retrograde accumulation was greatly reduced by colchicine, axotomy or destruction of the adrenergic nerve terminals by 6-hydroxydopamine. The rate of retrograde transport was the same as that of nerve growth factor (NGF) and tetanus toxin in sympathetic neurons. The retrograde transport of antibodies was confined to sympathetic neurons and could not be detect in either sensory or motor neurons.
