Ageing, immune fitness and cancer
Nature Reviews Cancer, Published online: 14 August 2025; doi:10.1038/s41568-025-00858-zAgeing reshapes immune composition, function and regenerative capacity, with profound effects on tumour immunity, cancer progression and treatment outcomes. In this Review, Dolan and colleagues examine how age-resolved immunoprofiling, insights from ageing haematopoiesis and preclinical modelling are uncovering immune ageing dynamics and therapeutic challenges — revealing new opportunities to optimize cancer therapy across diverse age groups.
