CTL granules: evolution of vesicles essential for combating virus infections.

Viral strategies for escaping apoptosis have co-evolved with the immune system, resulting in a complex balance of pro- and anti-apoptotic forces in virus-infected cells under attack by cytotoxic T lymphocytes (CTLs). Here, Joseph Trapani and colleagues argue that CTL cytolytic granules are the principal apoptotic means of eliminating viruses and possess multiple independent mechanisms to counter the viral anti-apoptotic machinery.
