“…The production of olive pollen extracts may present differences in allergen composition and potency as a result of the variability in cultivars origin (4)(5)(6). Some olive tree species like Frantoio, Gordal or Arbequina are less allergenic than Loaime, Hojiblanca or Picual species, regarding immunoblot detection of Ole e 1 (7).…”

“…In the case of the ashes, it is important to have more knowledge on the molecular allergen content in the pollen of the different species and genotypes (organisms: subgroup of the same taxonomic unit). Variety-specific differences have also been described in olive pollen [25]. From an allergy perspective, it is not advisable to plant nonindigenous ashes, the allergy potential of which is wholly unclear, in urban areas.…”

“…The same is likely to also apply to indigenous tree pollen. They are also more exposed to photochemical oxidants (predominantly composed of ozone) [9,25]. Children in urban centers grow up under increasing exposure to particulate and chemical industrial pollutants.…”

Background Allergy to ash pollen is common in some parts of Europe. Sensitization is overlooked if Oleaceae pollen allergens are not included in screening tests. Methods Between 1983 and 2007, sensitization to aeroallergens was systematically investigated using serological methods in 15-year-old school children (Immuno-CAP [carrier polymer] test). Samples from 1986 and 2006 were also tested using the immunosolid-phase allergen chip (ISAC) assay. School children with sensitizations in 1986 were retested in 2010. Airborne pollen concentrations were determined by the Swiss pollen measuring network. Results Sensitization (>0.7 kU/l) to ash pollen (Fraxinus americana t15)-16.3% (102/627)-was more frequent than to birch pollen (Betula verrucosa t3): 15.3% (96/627). ISAC assays performed in children in 1986 and 2006 revealed higher molecular seroprevalence for nOle e 1 (15%; 15/100) compared to rBet v 1 (12%; 12/100). Followed-up subjects (age, 39) showed an increase in sensitizations to ash pollen. IgE levels Dr. M.

“…The concentration level of the major olive pollen allergens, estimated using monoclonal antibodies alone or in combination with gel scanning densitometry, , indicates a variation between plant species . Cultivars and probably local variety or subvarieties of olive trees present special features that depend on their adaptation to the environment or ecotype . Ecosystem and crop management are factors that are able to induce changes in the allergenic profile of a given variety or cultivar .…”

Profiling of Hydrophilic Proteins from Olea europaea Olive Pollen by MALDI TOF Mass Spectrometry

The antigenic profile of Olea europaea pollen from different Mediterranean cultivars was obtained by MALDI mass spectrometry. A simple procedure of chemical fractionation of the whole antigen extract was developed, whereby less complex, or pure, fractions of antigen candidate were obtained prior to mass spectrometric analysis. Some of the features of protein structure and distribution probably depend on cultivar adaptation to the environment. The profilings of pollen proteins thus obtained allow the distinction of the analyzed cultivars into three distinct groups: (i) those characterized by a low Ole e 1 content; (ii) those over-enriched in Ole e 1 and (iii) that containing Ole e 3 and Ole e 7 only. The latter consists of at least four isoforms differing by the degree of glycosilation. These results demonstrate that the proposed experimental procedure, can supply valuable information on the antigens' micro heterogeneity.
