Immunity & Ageing, published since 2004, is a specialist open access journal dedicated to increasing knowledge about the impact of ageing on immune systems, the influence of aged immune systems on organismal well-being and longevity, and the potential for interventions to increase healthspan. The journal welcomes submissions dealing with any aspect of ageing in human and model organisms that relates to immune function. All articles undergo rapid and rigorous peer-review and all accepted articles are published open access to provide the highest visibility for authors’ work. The increasing realization that immune ageing and organismal ageing are intimately inter-related puts the immune system centre-stage in our efforts to understand and manipulate the ageing process and Immunity & Ageing continues to offer a specialized conduit for dissemination of new knowledge in this increasingly important arena.
