Thus far, information on IgE-binding sites of major allergen in ragweed pollen, Amb a 1, is very limited. A powerful experimental method to gain insights on the allergen epitopes is the selection of peptides from biological libraries that bind to anti-allergen antibodies. In this work, we aimed to map IgE epitopes of Amb a 1 using epitope-mimicking short peptides % mimotopes that were affinity-selected from phage-displayed random peptide libraries. The peptides weakly aligned with the Amb a 1 primary sequence, thus suggesting that the epitopes are conformational. When the peptides were mapped onto the surface of Amb a 1 homology model, the EpiSearch analysis predicted the location of four potential epitopic sites on surface patches centred at residues K104, S110, H214, and W312. The peptides matching to the predicted epitopes bound selectively to the IgE from pool of ragweed-allergic patients% sera and therefore represent mimetics of Amb a 1 IgE epitopes. The knowledge of IgE epitopes is a prerequisite for the rational design of molecular-based approaches to diagnosis and immunotherapy of allergic diseases</dc:description><dc:description xml:lang="sl">Ambrozija je pomemben vzrok sezonskih alergij. Do sedaj imamo zelo malo informacij o IgE vezavnih mestih na glavnem alergenu iz cvetnega prahu ambrozije, Amb a 1. Afinitetna selekcija peptidov iz bioloških knjižnic z uporabo specifičnih protiteles proti alergenu je uporabna laboratorijska metoda za določevanje epitopov. V tej raziskavi smo s pomočjo mimotopov, kratkih peptidov, ki posnemajo epitope, izoliranih iz bakteriofagnih knjižnic naključnih peptidov, določali IgE epitope Amb a 1. Izbrani peptidi so se le šibko ujemali s primarnim zaporedjem Amb a 1, kar je nakazovalo, da so epitopi konformacijski. Da bi jih določili, smo izdelali homologni model tridimenzionalne strukture Amb a 1, na katerega smo prilegali izbrane peptide. S pomočjo programa EpiSearch smo identificirali štiri potencialne epitope na površini alergena okoli aminokislinskih ostankov K104, S110, H214 in W312. Peptidni mimetiki predvidenih epitopov so se specifično vezali na IgE iz zmesi serumov za ambrozijo alergičnih pacientov in tako predstavljajo mimetike IgE epitopov Amb a 1. Poznavanje IgE epitopov je predpogoj za racionalno načrtovanje molekularnih pristopov v diagnostiki in imunoterapiji alergijskih bolezni</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-LJLZ92AS"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-LJLZ92AS" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-LJLZ92AS/585ab992-1a09-4c48-a754-3e09cf8a8f35/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Slovensko kemijsko društvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-LJLZ92AS/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-LJLZ92AS" /></ore:Aggregation></rdf:RDF>
