What classification is a dendritic cell?

mononuclear phagocytes
Dendritic cells (DCs) are considered as a subset of mononuclear phagocytes that composed of multiple subsets with distinct phenotypic features.

What are dendritic cells responsible for?

Dendritic cells (DC) are responsible for initiating all antigen-specific immune responses. As such, they are the master regulators of the immune response and serve this function by linking the microbial sensing features of the innate immune system to the exquisite specificity of the adaptive response.

What is licensing of dendritic cells?

Dendritic cell licensing refers to the phenomenon of upregulation of MHC class I and costimulators CD80/86 on dendritic cells after antigen presentation to CD4+ T cells via MHC class II and CD40-CD40L interactions have occurred.

Why dendritic cells are called so?

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.

What are the three types of dendritic cells?

Dendritic Cells They are abundant at body surfaces and within tissues, where they sense and sample the environment for self- and non–self-antigens. Three major subsets of DCs—plasmacytoid DCs, conventional DCs, and monocyte-derived DCs—are characterized by distinct origins, receptors, and functions.

Where is dendritic cells found?

Dendritic cells are found in tissue that has contact with the outside environment such as the over the skin (present as Langerhans cells) and in the linings of the nose, lungs, stomach and intestines. Immature forms are also found in the blood.

How do you increase dendritic cells?

Currently, it is possible to proliferate populations of DCs in vitro from various cellular sources including bone marrow, umbilical cord blood, and peripheral blood. Following appropriate stimulation, T cells can proliferate extensively in vitro.
