Dermatophagoides farinae allergens diversity identification by proteomics.

ABSTRACT: The most important indoor allergens for humans are house dust mites (HDM). Fourteen Dermatophagoides farinae allergens (Der f 1-3, 6, 7, 10, 11, 13-18, and 22) are reported although more than 30 allergens have been estimated in D. farinae. Seventeen allergens belonging to 12 different groups were identified by a procedure of proteomics combined with two-dimensional immunoblotting from D. farina extracts. Their sequences were determined by Edman degradation, mass spectrometry analysis, and cDNA cloning. Their allergenicities were assayed by enzyme-linked immunosorbent assay inhibition tests, immunoblots, basophil activation test, and skin prick tests. Eight of them are the first report as D. farinae allergens. The procedure of using a proteomic approach combined with a purely discovery appr
