abstract：:The transcription factor Blimp-1 regulates the overall accumulation of virus-specific CD8⁺ T cells during acute viral infections. We found that increased proliferation and survival of Blimp-1-deficient CD8⁺ T cells resulted from sustained expression of CD25 and CD27 and persistent cytokine responsiveness. Silencing of...
