What does DC mean in THERAPY
DC stands for dentritic cell. Dendritic cells are a type of antigen-presenting cells (APCs) that are found in the skin, lymphoid organs, and other tissues of the body. DCs play an important role in the immune response by capturing, processing, and presenting antigens to T cells.
DC meaning in Therapy in Medical
DC mostly used in an acronym Therapy in Category Medical that means dentritic cell i.e. antigen-presenting cells
Shorthand: DC,
Full Form: dentritic cell
i.e. antigen-presenting cells
For more information of "dentritic cell i.e. antigen-presenting cells", see the section below.
Functions of Dendritic Cells
- Antigen capture: DCs are able to capture antigens from the environment through various mechanisms, including phagocytosis, endocytosis, and the binding of antigens to specific receptors on the cell surface.
- Antigen processing: Once an antigen is captured, it is processed by the DC into smaller peptides that can be presented to T cells.
- Antigen presentation: The processed antigens are then presented to T cells in the context of major histocompatibility complex (MHC) molecules. This allows the T cells to recognize and respond to the antigen.
- Costimulation: DCs also provide costimulatory signals that are necessary for the activation of T cells. These signals include the expression of molecules such as CD80, CD86, and ICOS-L.
Types of Dendritic Cells
There are two main types of DCs:
- Myeloid DCs: These DCs are derived from myeloid progenitor cells and are found in the skin, lymphoid organs, and other tissues of the body.
- Plasmacytoid DCs: These DCs are derived from lymphoid progenitor cells and are found in the blood and lymphoid organs.
Essential Questions and Answers on dentritic cell i.e. antigen-presenting cells in "MEDICAL»THERAPY"
What is a dendritic cell (DC)?
A dendritic cell is a type of antigen-presenting cell that plays a critical role in the immune system. DCs capture and process antigens, which are molecules that can trigger an immune response. They then present these antigens to T cells, which activate the adaptive immune response.
What is the function of DCs in the immune system?
DCs are essential for the initiation of adaptive immune responses. They capture and process antigens from pathogens, and then present these antigens to T cells. This process activates the T cells, which can then kill infected cells or produce antibodies to neutralize the pathogen.
What are the different types of DCs?
There are two main types of DCs: myeloid DCs and plasmacytoid DCs. Myeloid DCs are the most common type of DC and are found in tissues throughout the body. Plasmacytoid DCs are less common and are found primarily in the blood and lymphoid tissues.
How do DCs capture and process antigens?
DCs capture antigens through a variety of mechanisms, including phagocytosis, endocytosis, and pinocytosis. Once the antigens are captured, they are processed into smaller peptides. These peptides are then bound to MHC molecules and presented to T cells.
What is the role of DCs in immune tolerance?
DCs play an important role in immune tolerance, which is the ability of the immune system to distinguish between self and non-self. DCs can induce tolerance by presenting antigens to T cells in a way that does not activate the T cells. This process helps to prevent the immune system from attacking the body's own tissues.
Final Words: Dendritic cells are essential for the immune response. They play a key role in capturing, processing, and presenting antigens to T cells, which allows the T cells to recognize and respond to the antigen.
