ABSTRACT We have investigated the occurrence and distribution of serotonin immunoreactive material in the adult mouse lung after treating the animals with the amine precursor 5-hydroxytryptophane. In this report, an immunocytochemical investigation has been undertaken. A widespread distribution of isolated endocrine cells and neuroepi­ thelial bodies was reported within the lung. Sorne serotoni immunoreactive intrinsic ganglia were also observed. The presence of serotonin immunoreactive material in the lung cells sug­ gests that these cells should be characterised as serotonin-containingor that they are able to uptake and decarboxylate the amine precursor.

Keywords: Serotonin, immunocytochemistry, lung.
