Název v původním jazyce

Influence of high-pressure treatment on allergenicity of rDau c1 and carrot juice demonstrated by in vitro and in vivo tests

Popis výsledku v původním jazyce

The aim of our study was to detect the influence of high-pressure treatment (HPT) on the allergenicity of recombinant allergen rDau c1 and carrot juice using in vitro and in vivo tests. The buffer solution of recombinant main carrot allergen rDau c1 forthe basophil activation test (BAT) and Western blot (WB) was used. Dau c1 was pre-treated by pressure 500 MPa for 10 min and different temperatures (30 °C, 40 °C, 50 °C) and pressure from 400 to 550 MPa for 3 and 10 min. Neither the HPT from 400 to 550 MPa for 3 and 10 min nor the HPT at 500 MPa for 10 min and temperatures 30 °C, 40 °C, and 50 °C had the influence on basophil activation by rDau c1. Serum samples of birch pollen allergic patients reacted in WB with solution of rDau c1 treated by HP 500 MPa for 10 min at temperature 30 °C, 40 °C, and 50 °C. This pressure procedure did not influence the immune reactivity of rDau c1 in WB test. The structural changes of rDau c1 caused by HPT studied by circular dichroismus spectra were foun
