Perforin Is Essential for Control of Ectromelia Virus but Not Related Poxviruses in Mice

Müllbacher, Arno, Hla, Ron Tha, Museteanu, Crisan, Simon, Markus M.

Wang, Yang, Lobigs, Mario, Lee, Eva, Müllbacher, Arno

C57BL/6J mice infected intravenously with the Sarafend strain of West Nile virus (WNV) develop a characteristic central nervous system (CNS) disease, including an acute inflammatory reaction. Dose...

Perforin and Fas Act Together in the Induction of Apoptosis, and Both Are Critical in the Clearance of Lymphocytic Choriomeningitis Virus Infection

Rode, Miriam, Balkow, Sandra, Sobek, Vera, Brehm, Reina, Martin, Praxedis, Kersten, Astrid, ...

In this report we questioned the current view that the two principal cytotoxic pathways, the exocytosis and the Fas ligand (FasL)/Fas-mediated pathway, have largely nonoverlapping biological roles....
