BACKGROUND Many asthmatic women complain of symptom exacerbations in particular periods, i.e. during pregnancy and menstrual cycles (perimenstrual asthma: PMA)". The goal of this study was to study the effect of the luteal and follicular phases of the menstrual cycle on bronchial reactivity (BR) in a group of asthmatic women. METHODS For this purpose, 36(More)
Cannabinoids have been shown to inhibit sensory nerve activation in guinea-pigs and humans. Their effects are mediated by specific activation of two types of receptors, named CB(1) and CB(2). The purpose of this study was to investigate the effects of WIN 55,212-2,(More)
Lung cancer is characterized by a high mortality rate probably attributable to early metastasis. Oxidative stress is involved in development and progression of lung cancer, through cellular and molecular mechanisms which at least in part overlap with proinflammatory pathways. Simvastatin is a statin with pleiotropic effects that can also act as an(More)
N-Palmitoyl-vanillamide (palvanil) is a non-pungent capsaicinoid, found in low amounts in Capsicum and shown to rapidly desensitize transient receptor potential vanilloid type-1 (TRPV1) channels to the action of capsaicin and to exert analgesic effects after local administration. We have investigated here if systemic administration of palvanil to mice(More)
Allergen exposure may induce changes in the brainstem secondary neurons, with neural sensitization of the nucleus solitary tract (NTS), which in turn can be considered one of the causes of the airway hyperresponsiveness, a characteristic feature of asthma. We evaluated neurofunctional, morphological, and biochemical changes in the NTS of naive or sensitized(More)
5-hydroxytryptamine (5-HT) has been reported to show some effects in respiratory tissues by activation of different subtype receptors. It has been demonstrated that 5-HT2 receptor activation causes in vivo and in vitro airways contraction and enhances effects of cholinergic nerve-mediated responses, whereas 5-HT1 receptor activation seems to be related to a(More)
BACKGROUND The need for new options for chronic lung diseases promotes the research on stem cells for lung repair. Bone marrow-derived mesenchymal stem cells (MSCs) can modulate lung inflammation, but the data on cellular processes involved in early airway remodeling and the potential involvement of neuropeptides are scarce. OBJECTIVES To elucidate the(More)
The heptadecapeptide nociceptin/orphanin FQ (N/OFQ) is the endogenous ligand for the N/OFQ peptide (NOP) receptor. It is cleaved from a larger precursor identified as prepronociceptin (ppN/OFQ). NOP is a member of the seven transmembrane-spanning G-protein coupled receptor (GPCR) family. ppN/OFQ and NOP receptors are widely distributed in different human(More)
Nociceptin/orphanin FQ (N/OFQ), the endogenous ligand for the N/OFQ peptide receptor (NOP), inhibits tachykinin release in the airway of several animal models. The aim of this study was to investigate the role of the N/OFQ-NOP receptor system in bronchoconstriction induced by sensory nerve activation in the isolated mouse lung. We used C57BL/6J NOP(+/+),(More)
