The major allergen of the Parietaria pollen contains an LPS-binding region with immuno-modulatory activity

2013

Background The major allergens in Parietaria pollen, Par j 1 and Par j 2, have been identified as lipid transfer proteins. The family of the Par j 1 allergens is composed of two isoforms, which differ by the presence of a 37 amino acid peptide (Par37) exclusive to the Par j 1.0101 isoform. The goal of this study was to elucidate the biological properties of the Par37 peptide. Methods In silico analysis, spectrofluorimetric experiments and in vitro cell culture assays were used to identify the biological properties of Par37. In addition, a mouse model of sensitization was used to study the influence of Par37 in the murine immune response. Results In silico analysis predicted that Par37 displ…

Mesure de l’efficacité de la lutte contre l’ambroisie : étude de faisabilité

2013

Common ragweed (Ambrosia artemisiifolia L.) is known for its high allergenic pollens and by the difficulty to control this invasive plant which make it a problem for public health and is a harmfulness in rural areas. This first work aims to make a feasibility study to verify the proper functioning of selected traps and the correct implementation of specific procedures. It was decided to use passive traps SIGMA2 (SIGMA2 Like Trap ou SLT). Two geographical areas were selected, each with 4 traps: an infested area in Isère and a slightly infested area in Côte d'Or. SLT traps used can well collect pollen from local areas, the collected quantities vary in a corresponding manner according to the d…
