Aspergillus fumigatus is a prime causative agent for various allergic and invasive aspergillosis. There has been a dramatic increase of such cases in last three decades yet the early diagnosis and virulence factor identification remains the challenge. In the present study secretome analysis of proteins isolated from the culture filtrate was done by 2D gel electrophoresis coupled with MS/MS and the immunosecretome analysis was carried out using immunoblotting of 2D transfer blots and probed with the sera of patients, immunized rabbit and mice. The identified proteins were analyzed further for homology with human proteins by BLAST search and for secretory signal by SignalP. A total of 65 protein spots from 2D gel resulted in identification of 24 different proteins along with their isoforms and out of which 15 proteins were identified as immunogenic in human. These findings may be helpful in the identification of virulence factors involved in aspergillosis and also useful as diagnostic markers. (C) 2011 Elsevier B.V. All rights reserved.
