Immunohistochemical localization of SNARE core proteins in intrapulpal and intradentinal nerve fibers of rat molar teeth

Highlights • Immunohistochemistry for SNARE core proteins, i.e. syntaxin 1, SNAP-25 and VAMP-2, was applied to decalcified rat molar teeth. • Most, if not all, intrapulpal and intradentinal nerve fibers were immunoreactive for these three SNARE proteins. • Electron microscopic analysis revealed the...

Description
Summary:Highlights • Immunohistochemistry for SNARE core proteins, i.e. syntaxin 1, SNAP-25 and VAMP-2, was applied to decalcified rat molar teeth. • Most, if not all, intrapulpal and intradentinal nerve fibers were immunoreactive for these three SNARE proteins. • Electron microscopic analysis revealed the presence of these SNARE proteins in axonal elements. • These SNARE proteins may participate in vesicle exocytosis in intrapulpal and intradentinal nerve fibers.
