(den-DRIH-tik sell) ( listen) A special type of antigen-presenting cell that activates T cells
a type of cell which takes up antigen and presents it to other cells of the immune system. It is a phagocyte which is present in lymphoid and other tissues. Dendritic cells in lymphoid tissues stimulate T-cell responses.
A powerful and effective antigen-presenting cell that is especially efficient at alerting resting helper T cells to the presence of foreign tissue. Dendritic cells get their name from the Greek word dendron ("tree") because the cell resembles a tree, with roots and branches spreading out from the main body of the cell.
one type of antigen-presenting cell with long branchlike projections, for example, Langerhans cells in the epidermis
Patrolling immune system cells that may begin with the HIV disease process by carrying the virus from the site of the infection to the lymph nodes, where other immune system cells become infected.
Immune cell that plays an important role in initiating and regulating immune responses.
An immune cell with thread-like tentacles called dendrites that "capture" antigen and present it to T-cells. Examples of dendritic cell types include Langerhans cells, found in the skin, and follicular dendritic cells, found in lymphoid tissues.
a special type of white blood cell (leukocyte) which circulates throughout the body looking to acquire antigens
A type of antigen presenting cell named for its long arms or dendrites that is important for initiating and controlling the overall immune response. These cells exist in many tissues including the skin and mucous membranes and can travel to lymph nodes or spleen to interact with other immune cells. In a sense, dendritic cells are the sentinels that alert other immune cells of an attack.
An immune cell that confers specificity to a CTL.
also known as interdigitating reticular cells, are found in T cell areas of lymphoid tissues. They have a branched or dendritic morphology and are the most potent stimulators of T cell response. Non-lymphoid tissues also contain dendritic cells but these do not seem to stimulate T cell responses until they are activated and migrate to lymphoid tissues. The dendritic cell derives from bone marrow precursors. It is distinct from the follicular dendritic cell that presents antigen to be cells.
an antigen-presenting cell with long, branching extensions or processes.
immune cell with thread-like tentacles called dendrites used to enmesh antigen, which they present to T cells. Langerhans cells, found in the skin, and follicular dendritic cells, found in lymphoid tissues, are both types of dendritic cells. (See also antigen-presenting cell.)
a type of immune system cell with many branches. Dendritic cells are found in the skin and mucosal membranes. They are typically the first to arrive at sites of injury or infection, where they bind to invaders and transport them to the lymph nodes where the cell-mediated immune response is initiated. Dendritic cells carry the CD4 surface marker, and may be among the first cells to be infected by HIV.
a cell with finger-like processes specialised for antigen presentation
A special type of antigen-presenting cell that activates T lymphocytes, B cells and natural killer cells,in the immune system. “Educated” dendritic cells are used in NWBT's vaccines in order to teach the immune system how to recognize and kill the cancer cells.
A type of antigen-presenting immune cell. Dendritic cells have elongated, tentacle like branches in which they trap foreign objects.
Dendritic cells (DCs) are immune cells and form part of the mammalian immune system. Their main function is to process antigen material and present it on their surface to other cells of the immune system. Dendritic cells are present in small quantities in tissues that are in contact with the external environment, mainly the skin (where they are often called Langerhans cells) and the inner lining of the nose, lungs, stomach and intestines.
