Similarities between A.P.U.D. cells and monoaminergic neurons: evidence for a dopamine uptake mechanism in C cells of chicken ultimobranchial gland / A. Di Lauro, M. Popoli, G. Campanella, U. Avati. - In: JOURNAL OF NEUROCHEMISTRY. - ISSN 0022-3042. - 34:3(1980), pp. 504-511.
Abstract:
The uptake of [3H]dopamine was studied in the C cells of chicken ultimobranchial gland (UBG). DA uptake appears to be an active and saturable mechanism (K(m) = 8.6 μM). The C cells' affinity for DA is intermediate between dopaminergic synaptosomes and such extraneural tissues as platelets and heart. UBG incubation with DA leads to the synthesis of a noticeable quantity of DOPAC, indirectly showing the presence of MAO activity. Thus UBG C cells, besides having both an embryological derivation from the neural crest and some morphological aspects similar to synaptosomes, also possess an active uptake mechanism for a central neurotransmitter.
