Translation factor eIF5a is essential for IFNγ production and cell cycle regulation in primary CD8+ T lymphocytes

The translational elongation factor eIF5a may have a function in T cell protein translation. Here the authors show that hypusination of eIF5a or deletion of eIF5a alters the profile of mRNA translation in T cells and that eIF5 regulates the proliferation and effector function of these T cells.
