The changes in the ganglioside composition in the brain of rainbow trout (Oncorhynchus mykiss) and common carp (Cyprinus carpio) during seasonal adaptation
The aim of this study was to determine concentration, composition and distribution of brain gangliosides in two poikilothermic fish species: eurythermic common carp (Cyprinus carpio) and stenothermic rainbow trout (Oncorhynchus mykiss). Animals were subjected to seasonal temperature fluctuations in their natural ecosystem and speciments were collected from January till June. The variability of brain gangliosides was investigated by means of biochemical analysis and immunohistochemical localization. Composition and distribution of brain gangliosides changes differently in common carp and rainbow trout. During the cold acclimatization increase of polysialylated ganglioside fractions was observed in common carp, while rainbow trout showed increase of trisialogangliosides. Rainbow trout showed decrease in GD1a content against GD1b, leading to increase in the biosynthesis of the higher sialylated fractions of the b- pathway during cold acclimation. Both species showed decrease of monosialogangliosides, and formation of higher sialyilated glycosphingolipid homologues. Immunohistochemical localization revealed different species specific changes in various parts of brain. The data support the hypothesis that the composition and distribution of brain gangliosides vary with the state of thermal adaptation.
