Abstract
Acute viral bronchiolitis by Respiratory Syncytial Virus (RSV) is the most common respiratory illness in children in the first year of life. RSV bronchiolitis generates large numbers of hospitalizations and an important burden to health systems. Neutrophils and their products are present in the airways of RSV-infected patients who developed increased lung disease. Neutrophil Extracellular Traps (NETs) are formed by the release of granular and nuclear contents of neutrophils in the extracellular space in response to different stimuli and recent studies have proposed a role for NETs in viral infections. In this study, we show that RSV particles and RSV Fusion protein were both capable of inducing NET formation by human neutrophils. Continue reading

Influence of gender and sexual reproductive state in concentration of CAN f 1 in the fur of dogs (Canis lupus familiaris)

World Allergy Organization Journal
Ano: 2015
Volume: 8
Número: 1

Authors: Maicon Paulo, Marconi Rodrigues De Farias, Fábio Nogueira, Michelle Barbosa, L Karla Arruda, Nelson Rosario Filho

Background
The allergens from cats and dogs have been implicated as extrinsic factors involved in sensitization, precipitation and exacerbation of allergic rhinitis and asthma in susceptible children and adults, at rates ranging from 10 to 25%. The major allergen from the epithelium of dogs is the Can f 1, responsible for the majority of sensitivity reactions to these. The Can f 1 is a lipocalin, which confers adhesive properties, derived from the sebaceous glands and found in fur, scales and saliva of dogs. The aim of this study is to assess the influence of gender and sexual reproductive state on concentrations of Can f 1 in the fur of dogs. Continue reading
