| Abstract |
Strongyloides stercoralis is an intestinal helminth that infects people worldwide. Hyperinfection or disseminated human strongyloidiasis can involve vital organs, leading to lethal outcomes.We analyzed immunoproteomics of antigenic spots, derived from S. stercoralis third-stage larvae and reacted with human strongyloidiasis sera, by two dimensional gel electrophoresis and immunoblotting. Of 26 excised antigenic spots analyzed by liquid chromatography–electrospray ionization–tandem mass spectrometry, 20 proteins were identified. Most proteins were associated with enzymes involved in the metabolic process, energy generation, and oxidation–reduction. The proteins relate to promotion of worm development, cell division, cell signaling and transportation, and regulation of muscular contraction. Identification of antigenic proteins shows promise in helping to discover potential diagnostic protein markers or vaccine candidates for S. stercoralis infection. |
