title="Allergy to grass pollen: mapping of Dactylis glomerata and Phleum pratense allergens for dogs by two-dimensional immunoblotting",
abstract=" Introduction:   Much less is known about grass-pollen allergens to dogs, when compared with humans. Genetic-based patterns might play an important role in sensitization profiles, conditioning the success of allergen-specific immunotherapy.    Aim : Mapping of  Dactylis glomerata  ( D. glomerata ) and  Phleum pratense  ( P. pratense ) allergens for grass pollen-sensitized atopic dogs, for better understanding how individual allergograms may influence the response to grass-pollen immunotherapy.    Material and methods : To identify  D. glomerata  and  P. pratense  allergoms for dogs, 15 individuals allergic to grass pollen and sensitized to  D. glomerata  and  P. pratense  were selected.  D. glomerata  and  P. pratense  proteomes were separated by isoelectric focusing (IEF), one-dimensional (1-D) and two-dimensional (2-D) sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Separated proteins were blotted onto Polyvinylidene difluoride (PVDF) membranes and allergens were identified by patient sera IgE in Western Blotting (WB).    Results : In  D. glomerata , 17 allergens were identified from IEF and 11 from 1-D SDS-PAGE, while from  P. pratense ,   18 and 6 allergens were identified, respectively. From 2-D SDS-PAGE 13 spots were identified from  D. glomerata  and 27 from  P. pratense .    Conclusions : Several similarities were found between dog and human  D. glomerata  and  P. pratense  sensitization profiles but no relationship between clinical signs and a specific pattern of allergen recognition was observed. Similarities were found in each patient pattern of sensitization between  D. glomerata  and  P. pratense , also suggesting cross-reactive phenomena. Further molecular epidemiology approach is needed to understand the role of the sensitization pattern in allergen-specific immunotherapy effectiveness in grass-pollen allergic dogs.",
