Innervation, Distribution And Morphology Of Calcitonin Gene Related Peptide And Substancep Immunoreactive Axons In The Whole-Mount Atria Of Fvb Mice, Liang Li
Electronic Theses and Dissertations
Degeneration of nociceptive afferent axons and terminals in the heart is associated with painless sudden cardiac death. However, innervation, distribution and morphological structures of sympathetic cardiac nociceptive afferent axons and terminals have not yet been fully characterized. The aim of the present study is to characterize the density, arrangement, and structural features of differentiated sympathetic afferent axons and terminals in whole-mount FVB mouse atria. FVB mice (3-6 months old) were perfused and the tissues were fixed. The right and left atria were processed with immunohistochemistry. Calcitonin gene-related peptide (CGRP) and substance P (SP) are two neuropeptides which have been widely …
