                              1. A postdoctoral position is available in Professor Cesar Picado laboratory. The position involves working wit a team of
                              scientists studying “Endogenous modulators (prostanoids, glucocorticoids) involved in the regulation of airway inflammation
                              and airways mucus secretion”.

                              The programme is a continuation of work recently published in: Eur Respir J 2009;33:502-8; Int Arch Allergy Immunol
                              2009;149:323-32; Respir Res 2008;9:72; Allergy 2008;63:1377-86, and Allergy 2008;63:1368-76, which has provided
                              evidences to support the concept that abnormalities in the regulation of the cyclo-oxygenase pathway may contribute to
                              excessive inflammatory and mucus hypersecretion responses in the airways of patients with asthma and rhinosinusitis,
                              specially in those patients with aspirin-induced bronchoconstriction. This alteration may also account for the poor response to
                              glucocorticoid therapy of both asthma and chronic rhinosinusitis/nasal polyposis.

                              Briefly, previous studies from others and our group have demonstrated low prostaglandin E2 (PGE2) production and down-
                              expression of cyclo-oxygenase 2 (Cox-2) mRNA in asthmatic patients, particularly in those with aspirin-intolerance. Using
                              animal models others and our group have reported that the blockage of the cyclo-oxygenase pathway has deleterious effects
                              on allergen-induced airway inflammation while the exogenous addition of PGE2 rescued the effects of allergen-induced injury.
                              However, is still unclear through which mechanisms PGE2 exerts its inhibitory role. The activity of PGE2 is mediated by four
                              receptors (EP1-EP4) encoded by distinct genes. Understanding the association between PGE2, receptor expression and cells
                              signalling pathways will offer new opportunities to discover new selective agents in the treatment of asthma and chronic

                              The purpose of this programme of work will be: to investigate the specific receptors and cell signalling pathways involved in
                              the anti-inflammatory effects of prostaglandin E2 in allergen-induced airway inflammation in asthma.

                              2. The project is likely to involve some or all of the following techniques:
