The Role of Neuropeptides in Stress and in Pathophysiology of EAE
Kramáriková, Ivana ; Slanař, Ondřej (advisor) ; Kmoníčková, Eva (referee) ; Slíva, Jiří (referee)
Introduction and Aim: Neuropeptides are widely distributed group of biologically active substances and their effects depend on their activity and localization of specific receptors. The mechanism of the regulatory / modulatory effects of neuropeptides has not been fully elucidated yet, and these gaps in our knowledge make it difficult for them to influence them therapeutically. Our hypothesis was that similar to the effects of the galaninergic system on the cardiovascular system, the galaninergic system may be one of the important modulators of the hypothalamic-pituitary-adrenal axis and may therefore modulate the stress response or pathophysiology of selected neurological diseases. The aim of our study was to investigate presence and expression of CRH and Galanin receptors in the basal conditions and in stress in adenohypohysis and in hypophysis and in pathological conditions - in the spinal cords in the murine model of multiple sclerosis, experimental autoimmune encephalomyelitis (EAE) and determine GalR1 cellular localization (oligodendrocytes, microglia, astrocytes, ependymal cells, and endothelial cells in the capillaries). Results: The expression of all tested galaninergic peptides was determined in the adenohypophysis. It was found that the expression of the GalR2 mRNA in adenohypophysis...
