Anti-inflammatory activity of Cymbopogon citratus leaves infusion via proteasom...
Francisco, Vera; Costa, Gustavo; Figueirinha, Artur; Marques, Carla; Pereira, Paulo; Neves, Bruno Miguel; Lopes, Maria Celeste; García-Rodríguez, CarmenEthnopharmacological relevance Cymbopogon citratus (DC.) Stapf leaves infusion is used in traditional medicine for the treatment of inflammatory conditions, however little is known about their bioactive compounds. Aim of the study Investigate the compounds responsible for anti-inflammatory potential of Cymbopogon citratus (Cy) on cytokines production induced by lipopolysaccharide (LPS) in human and mouse macro...
Pathogen Strategies to Evade Innate Immune Response: A Signaling Point of View
Neves, Bruno Miguel; Lopes, Maria Celeste; Cruz, Maria TeresaAn effective host defense against pathogens requires appropriate recognition of the invading microorganism by immune cells, conducing to an inflammatory process that involves recruitment of leukocytes to the site of infection, activation of antimicrobial effector mechanisms and induction of an adaptive immune response that ultimately will promote the clearance of infection. All these events require the coordina...
Cymbopogon citratus as source of new and safe anti-inflammatory drugs: Bio-guid...
Francisco, Vera; Figueirinha, Artur; Neves, Bruno Miguel; García-Rodríguez, Carmen; Lopes, Maria Celeste; Cruz, Maria Teresa; Batista, Maria TeresaEthnopharmacological relevance Aqueous extracts of Cymbopogon citratus (Cy) leaves are used in traditional medicine for the treatment of inflammatory conditions, however, little is known about their mechanism of action. Aim of the study The aim of this study is to explore the anti-inflammatory properties of Cymbopogon citratus leaves and their polyphenol-rich fractions (PFs), as well its mechanism of action i...
Influência do molibdénio na acumulação de nitratos nas folhas de alface (Lactuc...
Neves, Bruno Miguel PedrosoMestrado em Engenharia Agronómica - Instituto Superior de Agronomia ; In this study four field experiments and one pot experiment were conducted with the aim of studying the decrease of nitrate accumulation in the lettuce leaves. To achieve this objective the following issues were addressed: effects of molybdenum applied either in fertirrigation and/or foliar fertilization; the influence of different lettuce v...

Differential modulation of CXCR4 and CD40 protein levels by skin sensitizers an...
Neves, Bruno Miguel; Cruz, Maria Teresa; Francisco, Vera; Gonçalo, Margarida; Figueiredo, Américo; Duarte, Carlos B.; Lopes, Maria CelesteThe development of non-animal methods for skin sensitization testing is an urgent challenge. Some of the most promising in vitro approaches are based on the analysis of phenotypical and functional modifications induced by sensitizers in dendritic cell models. In this work, we evaluated, for the first time, a fetal skin-derived dendritic cell line (FSDC) as a model to discriminate between sensitizers and irritan...
