Follicular dendritic cells
Encyclopedia
Follicular dendritic cells (FDC) are cells of the immune system
found in lymph follicles of secondary lymphoid organs and tertiary lymphoid organs. They are probably not of hematopoietic origin, though they look similar to true dendritic cells due to their filiform dendritic processes, but are of stromal, mesenchymal origin. The term FDC was introduced to distinguish them from other stromal cells localizing in the B cell follicles, the reticular fibroblast cells. FDCs are originally defined as cells within lymphoid follicles, which trap immune complexes.
They attract B-cells with CXCL13
secretion; assist them in their maturation, presenting intact antigens. This occurs in the germinal centers of peripheral lymphoid organs and induces class switching and proliferation.
Immune system
An immune system is a system of biological structures and processes within an organism that protects against disease by identifying and killing pathogens and tumor cells. It detects a wide variety of agents, from viruses to parasitic worms, and needs to distinguish them from the organism's own...

CXCL13
C-X-C motif chemokine 13 also known as B lymphocyte chemoattractant is a protein that in humans is encoded by the CXCL13 gene.- Function :CXCL13 is a small cytokine belonging to the CXC chemokine family...
