What is dendritic cell differentiation?

Dendritic cells (DC) are bone marrow-derived cells that are specialized to take up, process and present antigen, and have the capacity to stimulate resting T cells in the primary immune response. DC differentiation from bone marrow precursors in enhanced by the cytokines GM-CSF and tumor necrosis factor-alpha.

What does dendritic cell represent?

Dendritic cells (DCs) represent a critical link between innate and adaptive immune responses and are the primary sensors of bacterial products as well as serving as antigen-presenting cells.

What is the main function of a dendritic cell?

Dendritic cells (DCs) represent a heterogeneous family of immune cells that link innate and adaptive immunity. The main function of these innate cells is to capture, process, and present antigens to adaptive immune cells and mediate their polarization into effector cells (1).

Are dendritic cells PBMCs?

15.1 Origin. Human peripheral blood mononuclear cells (PBMCs) are isolated from peripheral blood and identified as any blood cell with a round nucleus (i.e. lymphocytes, monocytes, natural killer cells (NK cells) or dendritic cells).

Where are dendritic cells derived from?

bone marrow
Dendritic cells (DCs) are uniquely potent in orchestrating T cell immune response, thus they are indispensable immune sentinels. They originate from progenitors in the bone marrow through hematopoiesis, a highly regulated developmental process involving multiple cellular and molecular events.

Can you culture dendritic cells?

Antigen-presenting dendritic cells are an important factor in studying the immune system. If you already have dendritic cells (DC) in your lab, you can culture them to achieve a desired phenotype and activate them to recognize immune or inflammatory responses.

How do dendritic cells work?

Dendritic cells (DCs) are antigen-presenting cells (also known as accessory cells) of the mammalian immune system. Their 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 the adaptive immune systems.

What do dendritic cells produce?

Dendritic cells (DCs) produce cytokines and are susceptible to cytokine-mediated activation. Thus, interaction of resting immature DCs with TLR ligands, for example nucleic acids, or with microbes leads to a cascade of pro-inflammatory cytokines and skewing of T cell responses.

Are dendritic cells white blood 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.

Where do dendritic cells in the body come from?

Dendritic cells (DC) are bone marrow-derived cells that are specialized to take up, process and present antigen, and have the capacity to stimulate resting T cells in the primary immune response. DC are a unique population that is likely to derive from a myeloid precursor cell.

How are monocyte-derived dendritic cells ( DC ) isolated?

Monocyte Isolation and Dendritic Cell (DC) Differentiation Peripheral blood mononuclear cells (PBMCs) were isolated from healthy blood donors by Ficoll-Hypaque (1.077 g/ml) density gradient centrifugation. CD14 + monocytes were isolated from PBMCs using immunomagnetic bead selection with CD14 microbeads (Miltenyi Biotec).

Can a leukemia cell line differentiate into DC?

It has been described that leukemia-derived cell lines are able to differentiate into functional DC, creating possibilities for the development of highly reproducible DC vaccines and providing in vitro model systems for in-depth studies about DC physiology.

Which is the best cell line for DC differentiation?
