A dendritic cell (DC) is an antigen-presenting cell (also known as an accessory cell) of the mammalian immune system. A DC's main function is to process antigen material and present it on the cell surface to the T cells of the immune system. They act as messengers between the innate and adaptive immune systems. [1]
Dendritic cells serve as a link between the bodily tissues and the innate and adaptive immune systems, as they present antigens to T cells, one of the key cell types of the adaptive immune system. [37] Granulocytes are leukocytes that have granules in their cytoplasm. In this category are neutrophils, mast cells, basophils, and eosinophils.
Macrophages, neutrophils, and dendritic cells are all cells of the innate immune system that utilize phagocytosis and are equipped with Toll-like receptors (TLR). Toll-like receptors are present on each of these cells and recognize a variety of microbial products resulting in the induction of more specific immune responses. [ 2 ]
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare type of myeloid cancer in which malignant pDCs infiltrate the skin, bone marrow, central nervous system, and other tissues. Typically, the disease presents with skin lesions (e.g. nodules, tumors, papules , bruise-like patches, and/or ulcers) that most often occur on the head, face ...

They are proteins expressed mainly by cells of the innate immune system, such as dendritic cells, macrophages, monocytes, neutrophils, as well as by epithelial cells, [3] [4] to identify two classes of molecules: pathogen-associated molecular patterns (PAMPs), which are associated with microbial pathogens, and damage-associated molecular ...
Follicular dendritic cells (FDC) are cells of the immune system found in primary and secondary lymph follicles (lymph nodes) of the B cell areas of the lymphoid tissue. [ 1 ] [ 2 ] [ 3 ] Unlike dendritic cells (DC), FDCs are not derived from the bone-marrow hematopoietic stem cell , but are of mesenchymal origin. [ 4 ]
Tolerogenic dendritic cells (a. k. a. tol-DCs, tDCs, or DCregs) are heterogenous pool of dendritic cells with immuno-suppressive properties, priming immune system into tolerogenic state against various antigens.
