Fra a 1 protein in strawberry causes oral allergic syndrome. Over 39 Fra a 1 paralogs have been identified in strawberry genome. Fra a 1.01 is major accumulating protein in edible organs. Strawberry fruits contain allergenic proteins that cause oral allergic syndrome. The hypothesized
We isolated eight phenolic constituents from Fragaria ananassa Duch. (strawberry) and determined their structures using 1D, 2D-NMR. Among the isolated compounds, linocinnamarin (LN), 1-O-trans-cinnamoyl-beta-d-glucopyranose (CG), and cinnamic acid (CA) exhibited antigen (Ag)-stimulated degranulation
We isolated the 4 kinds of flavonoids from strawberry 'Nohime' and examined the effect of these flavonoids on the degranulation in RBL-2H3 cells. The flavonoids were found to suppress the degranulation from Ag-stimulated RBL-2H3 cells to different extents. To disclose the inhibitory mechanism of
The Fra a 1 allergen in strawberry (Fragaria ananassa) is homologous to the major birch pollen allergen Bet v 1, which has numerous isoforms differing in terms of amino acid sequence and immunological impact. To map the extent of sequence differences in the Fra a 1 allergen, PCR cloning and
The strawberry (Fragaria X ananassa, Duch.) represents a relevant source of micronutrients, such as minerals, vitamin C, folate and phenolic substances, most of which are natural antioxidants and contribute to the high nutritional quality of the fruit. All these compounds are essential for health
Birch pollen allergic patients show cross-reactivity to vegetables and fruits, including strawberries (Fragaria × ananassa). The objective of this study was to quantify the level of the Fra a 1 protein, a Bet v 1-homologous protein in strawberry fruits by a newly developed ELISA, and determine the
We purified and identified an IgE suppressor from the strawberry 'Toyonoka', based on the decrease of IgE production in in vitro immunization (IVI). Gel filtration experiment indicated that fractions in a 15-48 kDa range and <10 kDa have an IgE suppressive activity. Furthermore, the fraction in
Proteomic screening of strawberry (Fragaria ananassa) yielded a 58% success rate in protein identification in spite of the fact that no genomic sequence is available for this species. This was achieved by a combination of MALDI-MS/MS de novo sequencing of double-derivatized peptides and
The strawberry fruit Fra a 1-proteins are homologues of the major birch pollen allergen Bet v 1 and have essential biological functions in pigment formation during fruit ripening. Patients affected by allergy against birch pollen tolerated fruits of a naturally occurring white-fruited F.×ananassa
The strawberry Fra a 1 allergen is a homolog of the major birch pollen allergen Bet v 1. It is synthesized by red ripe fruits of Fragaria x ananassa while white fruits of a mutant genotype, which is known to be tolerated by individuals affected by allergy, are devoid of it. Proteomic analyses have
