It has been known for a long time that T-cell precursors generated in the bone marrow migrate to the thymus, where T-cell development occurs. However, a fact often neglected is that, under physiological conditions, mature CD4 and CD8 lymphocytes undergo extensive migration from the blood to the bone marrow and vice versa. Here, we first review several observations showing that the bone marrow can function as a secondary lymphoid organ for both CD4 and CD8 cells, as well as a preferential homing site for memory T cells. Second, we discuss evidence that, a long time after priming, memory CD8 cells proliferate more extensively in the bone marrow than they do in either secondary lymphoid or extra-lymphoid organs. Finally, we propose that the bone marrow is a central organ in mature T-cell traffic and contributes greatly to long-term cytotoxic memory, which has implications for adoptive immunotherapy and vaccine design.

UI	MeSH Term	Description	Entries
D007156	Immunologic Memory	The altered state of immunologic responsiveness resulting from initial contact with antigen, which enables the individual to produce antibodies more rapidly and in greater quantity in response to secondary antigenic stimulus.	Immune Memory,Immunological Memory,Memory, Immunologic,Immune Memories,Immunologic Memories,Immunological Memories,Memory, Immune,Memory, Immunological
D008221	Lymphoid Tissue	Specialized tissues that are components of the lymphatic system. They provide fixed locations within the body where a variety of LYMPHOCYTES can form, mature and multiply. The lymphoid tissues are connected by a network of LYMPHATIC VESSELS.	Lymphatic Tissue,Lymphatic Tissues,Lymphoid Tissues,Tissue, Lymphatic,Tissue, Lymphoid,Tissues, Lymphatic,Tissues, Lymphoid
D001854	Bone Marrow Cells	Cells contained in the bone marrow including fat cells (see ADIPOCYTES); STROMAL CELLS; MEGAKARYOCYTES; and the immediate precursors of most blood cells.	Bone Marrow Cell,Cell, Bone Marrow,Cells, Bone Marrow,Marrow Cell, Bone,Marrow Cells, Bone

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
