Retrograde axonal transport of a wheat germ agglutinin-horseradish peroxidase conjugate in Aplysia californica. 1982

H B Kistler, and J H Schwartz

To begin examining retrograde transport in a single invertebrate neuron we have used wheat germ agglutinin conjugated to horseradish peroxidase (WGA-HRP), 18 h after the conjugate was injected extracellularly into the neuropil of the buccal ganglion of Aplysia, HRP reaction product could be detected cytochemically in putative lysosomes, cisternae and vesicles near Golgi in the giant metacerebral neuron (GCN) of the cerebral ganglion. Appearance of reaction product in the cell body was blocked by ligating GCN's axon and was inhibited by colchicine.

D010544 Peroxidases Ovoperoxidase
D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D003078 Colchicine A major alkaloid from Colchicum autumnale L. and found also in other Colchicum species. Its primary therapeutic use is in the treatment of gout, but it has been used also in the therapy of familial Mediterranean fever (PERIODIC DISEASE). Colchicine, (+-)-Isomer,Colchicine, (R)-Isomer
D004705 Endocytosis Cellular uptake of extracellular materials within membrane-limited vacuoles or microvesicles. ENDOSOMES play a central role in endocytosis. Endocytoses
D005724 Ganglia Clusters of multipolar neurons surrounded by a capsule of loosely organized CONNECTIVE TISSUE located outside the CENTRAL NERVOUS SYSTEM.
D006735 Horseradish Peroxidase An enzyme isolated from horseradish which is able to act as an antigen. It is frequently used as a histochemical tracer for light and electron microscopy. Its antigenicity has permitted its use as a combined antigen and marker in experimental immunology.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001048 Aplysia An opisthobranch mollusk of the order Anaspidea. It is used frequently in studies of nervous system development because of its large identifiable neurons. Aplysiatoxin and its derivatives are not biosynthesized by Aplysia, but acquired by ingestion of Lyngbya (seaweed) species. Aplysias
D001370 Axonal Transport The directed transport of ORGANELLES and molecules along nerve cell AXONS. Transport can be anterograde (from the cell body) or retrograde (toward the cell body).

D014909 Wheat Germ Agglutinins Lectins purified from the germinating seeds of common wheat (Triticum vulgare); these bind to certain carbohydrate moieties on cell surface glycoproteins and are used to identify certain cell populations and inhibit or promote some immunological or physiological activities. There are at least two isoforms of this lectin.
