1. 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

2. Involvement of the TRPV1 channel in the modulation of spontaneous locomotor activity, physical performance and physical exercise-induced physiological responses
Physical exercise triggers coordinated physiological responses to meet the augmented metabolic demand of contracting muscles. To provide adequate responses, the brain must receive sensory information about the physiological status of peripheral tissues and organs, such as changes in osmolality, temperature and pH. Most of the receptors involved in these affe

3. Cutaneous lesions sensory impairment recovery and nerve regeneration in leprosy patients
It is important to understand the mechanisms that enable peripheral neurons to regenerate after nerve injury in order to identify methods of improving this regeneration. Therefore, we studied nerve regeneration and sensory impairment recovery in the cutaneous lesions of leprosy patients (LPs) before and after treatment with multidrug therapy (MDT). The skin

4. Participation of neuronal nitric oxide synthase in experimental neuropathic pain induced by sciatic nerve transection
Nerve injury leads to a neuropathic pain state that results from central sensitization. This phenomenom is mediated by NMDA receptors and may involve the production of nitric oxide (NO). In this study, we investigated the expression of the neuronal isoform of NO synthase (nNOS) in the spinal cord of 3-month-old male, Wistar rats after sciatic nerve transecti

5. Alterations in the Renin-Angiotensin System in the contralateral carotid artery after balloon catheter injury / Alterações do Sistema Renina-Angiotensina na artéria carótida contralateral à lesão por cateter balão
Fifteen days after balloon catheter injury Emax of Ang II was increased in the contralateral artery as compared to values obtained in arteries from intact animals. This increase in Ang II Emax was not modified in the absence of the endothelium. The morphological and morphometric characteristics in the contralateral artery were not altered as compared to cont

6. Morfoquantitative and chemical coding analyses of the purinergic P2X2 receptor in myenteric plexus of female and male obese mice (ob/ob). / Análises morfoquantitativa e do código químico do receptor purinérgico P2X2 no plexo mioentérico do íleo de camundongos obesos fêmeas e machos (ob/ob).
The intestinal activities are coordinated by enteric nervous system, and dysfunctions in intestinal motility were observed in obese individuals. The enteric neurons have been demonstrated to express different purinergics receptors. This study aims to analyze the expression of P2X2 receptor and the chemical code in the myenteric neurons in obesity. Sample fro

7. TMEM16 proteins: the long awaited calcium-activated chloride channels?
Currents mediated by calcium-activated chloride channels (CaCCs), observed for the first time in Xenopus oocytes, have been recorded in many cells and tissues ranging from different types of neurons to epithelial and muscle cells. CaCCs play a role in the regulation of excitability in neurons including sensory receptors. In addition, they are crucial mediato

8. Activation of proteinase-activated receptor 2 activation, a signal to joint innate immune responses. / Ativação do receptor ativado por protease 2, um sinal para resposta imunológica inata na articulação temporomandibular.
We hypothesised that the early pro-inflammatory effects of proteinase-activated receptor 2 (PAR2) activation in the temporomandibular joint (TMJ) are mediated by neurogenic mechanisms. Immunofluorescence analysis revealed a high degree of neurons expressing PAR2 in retrogradely labelled trigeminal ganglion neurons. Furthermore, PAR2 immunoreactivity was obse

9. Estudo do efeito Antinociceptivo do Eugenol / Study of the antinociceptive effect of Eugenol
Eugenol is a fenolic derivative being chemically designated as 4-alil-2-metóxifenol, well-known usually as carnation essence, because this present in great quantity in the essential oil of carnation of India (Eugenia aromatic), but this present also in the cinnamon, sassafras and myrrh. Eugenol bears several pharmacological effects among them can highlight:

10. Study of purinergic receptors in glial cells from dorsal root ganglia. / Estudo dos receptores purinérgicos em células gliais do glânglio da raiz dorsal.
Purinergic receptors are expressed and play role in the sinalization between neurons and glia. In dorsal root ganglia the soma of the sensory neurons is surrounded by a layer of satellite glial cells, whose function is unclear. There are evidences that ATP is released by neurons to act on receptors in satellite cells. So far, the nature of the purinergic rec

11. Avaliação da sensibilidade cutânea em pés de pacientes diabéticos através do Pressure Specified Sensory Device TM / Evaluation of cutaneous sensibility threshold on the feet of diabetic patients with the Pressure Specified Sensory Device(TM)
Neuropathy is a severe progressive loss of protective sensation on the feet, making the patient more vulnerable to mechanical trauma and consequently more suitable to the development of chronic wounds, major distortion of the foot bone architecture and eventually to limb amputation. Prophylaxis should be enforced to avoid foot ulceration and for that, evalua

12. Análise das regiões promotoras dos genes de receptores olfatórios e de receptores de feromônios do tipo 1 / Analysis of promoter regions of the olfactory and type 1 vomeronasal receptor genes
In the mouse genome there are approximately 1000 genes that encode olfactory receptors (ORs) and 150 genes that encode type 1 vomeronasal receptors (V1Rs) dispersed in various chromosomes. Each olfactory or vomeronasal neuron selects one single allele from one single receptor gene (OR or V1R) for expression while the rest of the repertoire remains silenced.
