title: Cytochemical observations of the coiled bodies in neurons of rat sympathetic ganglia.
abstract: Coiled bodies were investigated by means of ultrastructural cytochemistry. Preferential staining methods for localization of various proteins (ribonucleoproteins, basic proteins, phosphoproteins and glycoproteins) and DNA were applied. The results of cytochemical tests revealed that coiled bodies have a proteinaceous nature. They are composed of ribonucleoproteins, probably of nucleolar origin. They also contain phosphoproteins and glycoproteins but lack cytochemically detectable DNA. Coiled bodies present ultrastructural and cytochemical characteristics similar to the fibrillar part of the nucleous and to the interchromatin granules. The origin and possible functional role of coiled bodies are briefly discussed.
