The existence of the cell organelle which is now known as Golgi apparatus or Golgi complex, or simply as 'the Golgi", was first reported by Camillo Golgi in 1898, when he described in nerve cells an 'internal reticular apparatus' impregnated by a variant of his chromoargentic staining. It soon became clear that the newly-identified cytoplasmic structure occurred in a variety of cell types. Howe...

Recently, we reported that two siblings presenting with the clinical syndrome congenital disorders of glycosylation (CDG) have mutations in the gene encoding Cog7p, a member of the conserved oligomeric Golgi (COG) complex. In this study, we analyzed the localization and trafficking of multiple Golgi proteins in patient fibroblasts under a variety of conditions. Although the immunofluorescent st...

The Golgi complex consists of a series of stacked cisternae in most eukaryotes. Morphological studies indicate the existence of intercisternal cross-bridge structures that may mediate stacking, but their identity is unknown. We have identified a 400-kDa protein, giantin, that is localized to the Golgi complex because its staining in double immunofluorescence experiments was coincident with that...

We investigated the morphological alterations in the Purkinje cells (PCs) of the cerebellar cortex of young adult (2–3 years old) and old cats (12–13 years old). Rapid Golgi staining was used to visualize dendritic arborizations and spines, and routine Nissl staining was applied to visualize the somatic configuration of the PCs. The height, width and area of the dendritic network were measured,...

A variety of peripheral membrane proteins associate dynamically with Golgi membranes during the budding and trafficking of transport vesicles in eukaryotic cells. A monoclonal antibody (AD7) raised against Golgi membranes recognizes a peripheral membrane protein, p200, which associates with vesicles budding off the trans-Golgi network (TGN). Based on preliminary findings, a potential associatio...

In 1906, Golgi and Ramón y Cajal shared the Nobel Prize in Physiology or Medicine "in recognition of their work on the structure of the nervous system". However, it was an unusual occasion in the history of Nobel Prize award because their views on the structure of the nervous system were not only different but even opposite, creating the "storm center of histological controversy". Furthermore, ...

Electrophoretic analysis of the Golgi apparatus isolated by differential centrifugation from radiolabeled cells infected with foot-and-mouth disease virus showed about 10 protein bands. The virus-induced RNA polymerase was identified by immunoprecipitation and electron microscope staining procedures. Pulse-chase experiments indicated that the polymerase passed through the Golgi apparatus in les...

Normal, unimmunized mouse serum from several strains (BALB/c, C57/b, DBA/2, NZB, SJL, CD/1) contains an endogenous IgG antibody that localizes to the Golgi complex of rat pancreatic acinar cells. Treatment of pancreatic acini with 5 microM monensin resulted in the swelling and vacuolization of the Golgi cisternae, and in a corresponding annular staining by the mouse serum as observed by immunof...

We here present an image from the rare original slides from Camillo Golgi (Figure 1), which are kept at the Golgi Museum and at the Museum for the History of the University of Pavia (Pavia, Italy). Camillo Golgi (1843 – 1926), Professor of General Pathology and Histology at the University of Pavia, provided seminal scientific contributions, including in 1898 the discovery of the cell organelle ...
