CCL21(redirected from secondary lymphoid-tissue chemokine)
Also found in: Acronyms.
CCL21A gene on chromosome 9p13 that encodes a CC-type cytokine, which is characterised by two adjacent cysteines and, as with all cytokines, is involved in immunoregulatory and inflammatory processes. CCL21 binds CCR7, inhibits haemopoiesis and is chemotactic for thymocytes and activated T cells—but not B cells, macrophages or neutrophils; it may also play a role in homing lymphocytes to secondary lymphoid tissue.
