Follicular dendritic cells (FOe) are unique among cells of the immune system. While their morphological characteristics re sulted in their inclusion as a 'dendritic cell type', tt1ey differ quite significantly from the other members of the dendritic cell family. In contrast to T-cell-associated.

Follicular dendritic cells (FDCs) are stromal cells residing in primary follicles and in germinal centers of secondary and tertiary lymphoid organs (SLOs and TLOs). There, they play a crucial role in B-cell activation and affinity maturation of antibodies. FDCs have the unique capacity to bind and retain native antigen in B-cell follicles for long periods of time. Mechanisms of Antigen Delivery to FDCs. A common observation was that even though most of the antigen was endocytosed by phagocytic cells, some remained extracellularly on the surface of cells, whose identity was obscure at that time.

Follicular dendritic cells (FDCs) are a separate population of dendritic cells that present opsonized . Components of the Immune System.
Follicular dendritic cells (FDCs) are a separate population of dendritic cells that present opsonized antigen to B cells and are likely a key player in antigen presentation. Antigen-presenting follicular dendritic cells (FDCs) are mainly found in the two deeper zones, and cell death by apoptosis occurs primarily in the basal light zone, where tingible body macrophages are also located. iv) Follicular Dendritic Cells.

The cardinal feature of FOe is to trap and retain antigen on the surface of their dendritic processes for extended amounts of time and it is this feature that provides the conceptual compo nent for the title of this book.

Follicular dendritic cells (FDCs) are cells of the immune system found in primary and secondary lymph follicles of the B cell areas of the lymphoid tissue. These cells were first described in 1965 and, although they have a very dendritic morphology, are not dendritic cells (DCs). Unlike DCs, FDCs are not derived from the bone-marrow hematopoietic stem cell, but are of mesenchymal origin.

Antigen-Presenting Cells. Lymphocytes are the principal cell players in the adaptive immune response. B lymphocytes (B cells). T lymphocytes (T cells). Natural killer (NK) cells. Most of these cells are found in the blood. Most dendritic cells are part of the myeloid lineage of hematopoietic cells and arise from a precursor that can also differentiate into monocytes but not granulocytes. They represent 20% to 40% of circulating white blood cells and 99% of cells in the lymph. Lymphocytes can be broadly subdivided into three major populations on the basis of functional and phenotypic differences: B lymphocytes (B cells).
Dendritic cells (DCs), named for their probing, ‘tree-like’ or dendritic shapes, are responsible for the initiation of adaptive immune responses and hence function as the ‘sentinels’ of the immune system. Paul Langerhans first described DCs in human skin in 1868 but thought they were cutaneous nerve cells. DCs are bone marrow (BM)-derived leukocytes and are the most potent type of antigen-presenting cells. They can also be propagated in vitro from BM and blood using various combinations of growth factors, such as granulocyte macrophage-colony stimulating factor (GM-CSF) and Flt3 ligand.
