What is dendritic cell migration?
Table of Contents
Dendritic cells (DCs) travel through lymphatic vessels to transport antigens and present them to T cells in lymph nodes. DCs move directionally toward lymphatics by virtue of their CCR7 and a CCL21 chemotactic gradient.
Can dendritic cells migrate?
Dendritic cells (DCs) are potent and versatile antigen-presenting cells, and their ability to migrate is key for the initiation of protective pro-inflammatory as well as tolerogenic immune responses.
What are the four types of dendritic cells?
The different subtypes of dendritic cells (e.g. Langerhans cells, Plasmacytoid DC, Interdigitating DC, and Myeloid DC) not only have different origins, but also different receptors and varying functions.
What causes dendritic cells to migrate?
Abstract. Dendritic cells are potent antigen-presenting cells endowed with the unique ability to prime T-cell responses. To present foreign antigens to na ive T cells, dendritic cells must migrate from inflamed or injured peripheral tissues to the closest draining lymph nodes through afferent lymphatic vessels.
What is dendritic cell?
(den-DRIH-tik sel) A special type of immune cell that is found in tissues, such as the skin, and boosts immune responses by showing antigens on its surface to other cells of the immune system. A dendritic cell is a type of phagocyte and a type of antigen-presenting cell (APC).
What classification of cell is a dendritic cell?
antigen-presenting cells
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.
Where do dendritic cells reside?
Dendritic cells are present in those tissues that are in contact with the external environment, such as the skin (where there is a specialized dendritic cell type called the Langerhans cell) and the inner lining of the nose, lungs, stomach and intestines. They can also be found in an immature state in the blood.
Where do dendritic cells go?
Introduction. Dendritic cells (DCs) (see footnote) can be found in three types of location within the body. They are present as ‘immature’ cells in peripheral tissues, especially tissues that are exposed to the external environment, including the skin, lungs and intestine.
What are dendritic cells?
A special type of immune cell that is found in tissues, such as the skin, and boosts immune responses by showing antigens on its surface to other cells of the immune system. A dendritic cell is a type of phagocyte and a type of antigen-presenting cell (APC).
What is the main function of dendritic cells?
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).

What is the transwell migration assay?
Introduction The transwell migration assay is a commonly used test to study the migratory response of endothelial cells to angiogenic inducers or inhibitors. This assay is also known as the Boyden or modified Boyden chamber assay.
How do you migrate cells to a Transwell plate?
Migration Protocol: Cells (5 × 104 -2 x105 cells per well) were seeded in top chambers of the transwell plates in FBS-free media with membrane inserts without matrigel coated. To the well of the plate (lower compartment), add 0.6ml DMEM supplemented with 10% FBS as attractant. Incubate the plate at 37 °C for 16-48h.
How do you do transendothelial migration assay?
By growing the endothelial cells on the inverted transwell insert, cells used for the transendothelial migration assay will initially contact the basal, or abluminal, surface of the endothelial cells, thus recapitulating lymphatic transendothelial migration in vivo.
What is plating step 3 in transwell assay?
Plating transwell insert, step 3: The standard transwell assay requires that cells be placed in the upper chamber of the transwell apparatus. If the endothelial cells were grown on the upper surface of the insert, T cells would first contact the apical, or luminal, surface of the endothelial cells.
