2. Evaluation of serum ghrelin, nesfatin-1, irisin, and vasoactive intestinal peptide levels in temporal lobe epilepsy patients with and without drug resistance: a cross-sectional study
SUMMARY OBJECTIVE: Epilepsy is a common disorder that affects the nervous systems of 1% of worldwide population. In epilepsy, one-third of patients are unresponsive to current drug therapies and develop drug-resistant epilepsy. Alterations in ghrelin, nesfatin-1, and irisin levels with epilepsy were reported in previous studies. Vasoactive intestinal peptid

3. Modulatory effects of neuropeptides on pentylenetetrazol-induced epileptic seizures and neuroinflammation in rats
RESUMO OBJETIVO Nosso objetivo foi explorar os efeitos dos neuropeptídeos grelina, obestatina e peptídeo intestinal vasoativo (VIP) nas convulsões e concentrações plasmáticas de biomarcadores neuroinflamatórios, incluindo peptídeo relacionado ao gene da calcitonina (CGRP), substância-P (SP) e interleucina-1 beta (IL-1β) em convulsões induzidas p

4. Interactions between prolactin and kisspeptin to control reproduction
ABSTRACT Prolactin is best known for its effects of stimulating mammary gland development and lactogenesis. However, prolactin is a pleiotropic hormone that is able to affect several physiological functions, including fertility. Prolactin receptors (PRLRs) are widely expressed in several tissues, including several brain regions and reproductive tract organs.

5. Atopic dermatitis: allergic dermatitis or neuroimmune dermatitis?
Abstract: Advances in knowledge of neurocellulars relations have provided new directions in the understanding and treatment of numerous conditions, including atopic dermatitis. It is known that emotional, physical, chemical or biological stimuli can generate more accentuated responses in atopic patients than in non-atopic individuals; however, the complex ne

6. Does dexamethasone act in neuropeptides SP and CGRP in neurogenic inflammation of the skin? An experimental study
PURPOSE: To investigate the neuropeptides substance P (SP) and calcitonin gene-related peptide (CGRP) after subcutaneous injection of dexamethasone prior to skin incision in rats.METHODS:Twenty seven Wistar-EPM-1 rats were randomly divided into three groups. The sham group (SG) of rats was injected with 0.9 % saline. The second group (Dexa) was injected with

7. Neuropeptide Y, substance P, and human bone morphogenetic protein 2 stimulate human osteoblast osteogenic activity by enhancing gap junction intercellular communication
Bone homeostasis seems to be controlled by delicate and subtle “cross talk” between the nervous system and “osteo-neuromediators” that control bone remodeling. The purpose of this study was to evaluate the effect of interactions between neuropeptides and human bone morphogenetic protein 2 (hBMP2) on human osteoblasts. We also investigated the effects

8. Neuropeptides in the posterodorsal medial amygdala modulate central cardiovascular reflex responses in awake male rats
The rat posterodorsal medial amygdala (MePD) links emotionally charged sensory stimuli to social behavior, and is part of the supramedullary control of the cardiovascular system. We studied the effects of microinjections of neuroactive peptides markedly found in the MePD, namely oxytocin (OT, 10 ng and 25 pg; n=6/group), somatostatin (SST, 1 and 0.05 μM; n=

9. Effects of subcutaneous carbon dioxide on calcitonin gene related peptide and substance P secretion in rat skin
PURPOSE: To investigate the subcutaneous injection of carbon dioxide (CO2) on neuropeptides Calcitonin Gene-Related Peptide (CGRP) and Substance P (SP) secretion in rat skin.METHODS: Fifty-six Wistar-EPM rats were distributed in two groups: one for CGRP analysis, the other for SP analysis. Each group was subdivided into four subgroups: control (Cont), contro

10. Effects of nitric oxide on magnocellular neurons of the supraoptic nucleus involve multiple mechanisms
Physiological evidence indicates that the supraoptic nucleus (SON) is an important region for integrating information related to homeostasis of body fluids. Located bilaterally to the optic chiasm, this nucleus is composed of magnocellular neurosecretory cells (MNCs) responsible for the synthesis and release of vasopressin and oxytocin to the neurohypophysis

11. Cholecystokinin modulation of maternal behavior
Maternal behavior is regulated by several neurotransmitters, neuropeptides, and hormones. This mini-review focuses on the role of cholecystokinin (CCK), a neuropeptide and gut hormone best known as a satiety signal, in mediating maternal behavior. In addition to the role of CCK in the infant in mother-infant interactions, maternal CCK appears to also be impo

12. Distribuição dos neurônios e campos terminais que expressam a urocortina 3 no sistema nervoso central de primata não-humano (Cebus apella). / Distribution of neurons and terminal fields that express the Urocortin 3 in the central nervous systems of primate non-human (Cebus apella).
Introdução: A urocortina 3 (UCN 3) é um neuropeptídeo pertencente a família CRF, com seletividade de ligação a receptor CRF2. Em roedores as células UCN 3 se localizam principalmente em hipotálamo e amígdala, mas o mapeamento não foi realizado em modelo de primata não-humano. Objetivo: realizar o mapeamento da distribuição da UCN 3 no sistema n
