Endocytosis of cholera toxin into neuronal GERL.
Cholera toxin linked covalently by glutaraldehyde to horseradish peroxidase was incubated with cultured chicken sympathetic neurons at 4 degrees. Cells were washed and brought to 37 degrees to permit endocytosis of bound toxin on plasma membranes. Massive internalization of the ligand into vesicles and cisterns of the Golgi--endoplasmic reticulum--lysosome (GERL) system was demonstrated by the ...
متن کاملCholera Toxin
Vibrio cholerae, the causative agent of cholera, requires two coordinately regulated factors for full virulence: cholera toxin (CT), a potent enterotoxin, and toxin-coregulated pili (TCP), surface organelles required for intestinal colonization. The structural genes for CT are shown here to be encoded by a filamentous bacteriophage (designated CTXCP), which is related to coliphage Ml 3. The CTX...
متن کاملDil and diO: versatile fluorescent dyes for neuronal labelling and pathway tracing.
The fluorescent carbocyanine dyes dil and diO have an extensive history of use in cell biology, but their use as neuronal tracers is relatively recent. We found in 1985 that these molecules were excellent retrograde and anterograde tracers in the developing nervous system. We went on to show that these dyes were retained in neurons placed in culture, that they initially labelled the processes a...
متن کاملCholera toxin internalization and intoxication.
We read, with considerable dismay, a recent Research Article on cholera toxin (CT) internalization (Torgersen et al., 2001), in which the authors extensively challenged methods, results and conclusions that we had published four years ago (Orlandi and Fishman, 1998). As space limits a point-by-point rebuttal of their comments and critique of the many deficiencies in their study, we encourage re...
متن کاملNeuronal tracing
Received 2 January 2003; accepted 29 January 2003 ABSTRACT The tracing of neural pathways continues to be an important concern for neuroanatomy. During the second half of the nineteenth century, at a time when the foundations of neuroanatomy were being established, tracing pathways often required laborious dissections by hand. Then, neuroanatomy experienced a methodological revolution in the be...
