T-cell responses are dysregulated in aged humans and mice, which leads to poor antitumour responses. Here, the authors demonstrate that this phenomenon is at least partially due to an overproduction of IL-6 caused by ageing and its inhibitory effect on Th1 differentiation of tumour-specific CD4 T cells.
