Key result
Pestivirus glycoprotein Erns strongly inhibits protein synthesis and induces lymphocyte apoptosis in vitro.
Why the study?
Pestivirus infections cause leukopenia and immunosuppression, but the role of glycoprotein Erns in these processes was unclear.
Population
Porcine, bovine, ovine, and human lymphocytes and epithelial cells in vitro
Comparison
Exposure to glycoprotein Erns vs no exposure
Design
In vitro experimental study

Erns may drive pestivirus immunosuppression via lymphocyte apoptosis; extends in vitro findings across species but leaves open in vivo and clinical relevance.
The pestivirus envelope glycoprotein Erns induces apoptosis in lymphocytes across multiple species, suggesting a key role in viral pathogenesis and immunosuppression.
Bruschke et al. (1997) studied Pestivirus infection (in vitro). Glycoprotein Erns was evaluated on Lymphocyte proliferation, protein synthesis, and apoptosis. Glycoprotein Erns of pestiviruses strongly inhibited protein synthesis and induced apoptosis in porcine, bovine, ovine, and human lymphocytes in vitro.
