The subcellular localization of immunoglobulin in mouse plasma cells, as studied with immunoferritin cytochemistry on ultrathin frozen sections

Abstract: Cells of mineral oil-induced plasmacytomas (MOPC) and normal plasma cells from mouse lymph nodes were used to study the intracellular localization of IgG by means of immunoferritin cytochemistry on ultrathin frozen sections IgG was demonstrated in the rough endoplasmic reticulum, in virus-containing smooth ER of the tumor cells, in peripheral elements at the cis-side of the Golgi complex, and in all Golgi cisternae. It is suggested that the peripheral elements transfer IgG molecules from the RER to the Golgi c… Show more

“…This observation is in accordance with studies localizing secretory and membrane proteins in the pancreas (23), IgG in plasma cells (24), and VSV-G in Chinese hamster ovary cells (25,26). In all cases, each of the proteins were found in all cisternae of the Golgi stack.…”

“…The cellular morphology of the pre-PC was more consistent with GC cells than mature PCs (Figure 1D), although they showed some expansion in their ER, consistent with early stages of plasma cell differentiation (Geuze and Slot, 1980). …”

“…The secretory material is rapidly transported in small vesicles from the Golgi complex and gains the exterior by a fission-fusion process at the plasma membrane. These transport vesicles have half-life of only some 10 min and are not electron-dense (Geuze & Slot, 1980;Kelly, 1985). In AR4-2J cells, such transport vesicles are therefore likely to be responsible for basal amylase secretion via the constitutive pathway with freshly synthesised amylase largely confined to these small transport vesicles.…”
