The vagus nerve is responsible for efferent and afferent innervation of the gastrointestinal tract. The efferent fibres originate from neurons located in the dorsal motor nucleus of the vagus (DMX) and control mainly the gastric motor and secretory function. The main goal of our study was to examine expression of ChAT, SP, LENK, NOS and CART in the neuronal matrix of the porcine DMX. Double-labeling...
The vasoactive intestinal peptide (VIP) and opioid family member Leu⁵-enkephalin (LENK) have already been established as playing independently significant roles in the functioning of the female genital tract. However, the mutual influence of both neuropeptides on female genital function has not been examined until now. Therefore, the aim of this study was to compare the distribution of VIP- and/or...
Recent decades has brought significant advances in our knowledge of the chemical coding and function of enteric neurons. Calcium ions are important second messenger involved in many aspects of neuron physiology. In the present study, we analyzed immunohistochemically the presence of calcium binding proteins (calretinin and calbindin) in various subpopulations of enteric neurons from the ovine duodenum...
Previous immunocytochemical studies provided conflicting data concerning occurrence of the CGRP-immunoreactive neuronal cell bodies in the porcine spinal cord. In the present study, we have investigated expression of the CGRP and its possible coexpression with ChAT in the gray matter of the thoracic, lumbar and sacral spinal cord of the pig. Our study revealed a large number of CGRP-immunoreactive...
