Vaccination of pigs with alphavirus replicon particles expressing PRRSV ORF 3, 4, 5 and 6
June 21, 2010By D.L. Hank Harris
The objective of this project was to evaluate alphavirus replicon particles (RP) expressing various PRRSV proteins as vaccine candidates. Previous work has identified the minor structural...

Development of a rapid, swine-specific test to simultaneously detect multiple immune proteins (cytokines) affected by PRRSV infection
June 18, 2010By Jane Christopher-Hennings
Cytokines are small secreted proteins which mediate and regulate immunity to viral infections in swine and other species. Evidence suggests that PRRSV does not induce early, effective...

Identifying PRRSV structural components that activate regulatory T cells and diminish protective immunity
April 26, 2010By Tanya LeRoith
This study was designed to test the hypothesis that certain structural components of PRRSV drive the activation of regulatory T cells (Tregs). Activating these T cells would thereby diminish the...
