Dictyosome
A dictyosome (of the Greek διχτν (- ο), “in form of net” and σωμος, “body”) is a membrane stacking of saccules of form discoïdale belonging to the Appareil of Golgi of a cell. The apparatus of Golgi can be composed of one or more dictyosomes according to the type of cells. Within a dictyosome , the face cis indicates the saccules located central side of the cell. The face trans is consisted of the external saccules. One can also distinguish from the median compartments between the two precedents.
The face cis is the reception point of blisters coming from a endoplasmic Réticulum. These blisters transport the Protéine S translated of ARN m in the endoplasmic reticulum. The Protein S and the Lipide S undergo a series of transformations (Glycosylation, assembly of the Protéoglycane S, etc) during their transit in the saccules of the dictyosome. This transit is carried out via small blisters golgiennes transporting the products of the face cis , towards the face trans . The modifications operated on proteins and the lipids are ordered perfectly in each compartment. All the products thus formed end in blisters intended either for secretion and the membrane renewal by insertion of the walls vésiculaires in the plasmic membrane, or with the formation of Lysosome S.
