•The immune system undergoes profound age-related changes.•Aging affects bone marrow immune cells and their precursors.•The bone marrow provides a survival niche for memory T cells and plasma cells in mice and humans and the composition of the bone marrow niche seems to be affected by aging.
With aging the immune system undergoes significant age-related changes. These age-dependent changes are referred to as immunosenescence and are partially responsible for the poor immune response to infections and the low efficacy of vaccination in elderly persons. Immunosenescence is characterized by a decrease in innate and adaptive cell-mediated immune function in the peripheral blood and the bone marrow. The aging of bone marrow cells and in particular, of adaptive immune cells in the bone marrow has been addressed relatively rarely. It is therefore the goal of this review to summarize what is known about the effect of age on bone marrow immune cells and their precursors in mice and humans.
