Proteomics analysis of differential expression of chicken brain tissue proteins in response to the neurovirulent H5N1 avian influenza virus infection.
A certain H5N1 avian influenza virus has gained the ability to cause the classic central nervous system dysfunction in poultry and migratory birds. This study presents the proteomics analysis on the change of proteins to H5N1 avian influenza virus with neurovirulence infection in chicken brain tissue. By using 2-DE, coupled with MALDI-TOF MS/MS, we identified a set of differentially expressed cellular proteins, including 18 up-regulated proteins and 13 down-regulated proteins. The most significant changes were found in cytoskeleton proteins, proteins associated with the ubiquitin-proteasome pathway, and neural signal transduction proteins. Some identified proteins such as CRMP and SEP5 were found to participate in the pathogenesis progress of Parkinson's and Huntington's diseases, which also developed encephalitis accompanied with CNS dysfunction. The obtained data can provide insight into the virus-chicken brain tissue interaction and reveal the potential mechanism of the neuropathogenesis when the host was infected by the neurovirulent avian influenza virus.
