Abstract:
Chemokines are a superfamily of small cytokines with activities ranging from leukocyte traffick to hematopoiesis, angiogenesis, and tissue organogenesis. Secondary lymphoid-organ chemokine (SLC/CCL21) was originally reported as a chemokine constitutively expressed by stromal cells and high endothelial venules in secondary lymphoid tissues and endothelium of afferent lymphatics, directing CCR7+ cells. More recently, others and we have demonstrated that SLC/CCL21 is up-regulated in different skin inflammatory conditions. Thereafter, this molecule is much more than a constitutive chemokine, which could play a role in effector and regulatory immune functions.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
