Dendritic Cells

Dendritic cells perform their daily tasks by acting as an antigen encloseing cell to efficiently introduce the antigen to separate immune cells identify in the body. The Dendritic cell activates when it take notes a harmful unusual substance in the body such as a bacteria, parasite, or viruses. Once the dendrite cell detects the strange substance it, it captures it and deports the antigen to the other(a) immune cells located in the body. The interactions of dendritic cells differ depending on the locations in the body. Some of the most common origins where dendritic cells be present are: the struggle, lymph nodes, and the spleen. Dendritic cells are located in the discase and mucus passages, because a virus or opposed substance is most likely transmitted through these openings. The dendritic cells located on the skin are as intimately as know as the immature head, because of their low nation of molecules (CD80, CD86,CD83).The dendritic cells in the immature stage basically middling lay well-nigh until the immune system is invaded. Once a virus or bacteria enter the dendritic cells instantly activate, but it is non mature bountiful to be able to respond. The skin overly does not require a mature enough phenotype. The dc cells that lack maturation to respond to the viral substance, penetrates into the openings of the body.

The skin dc cells are too immature to reach the t-cells, so in response it carries the antigen to mature part of the body cognise as the lymph nodes. Once the cell reaches the lymph nodes, it no longer require t o present antigens to the rest of the immune! system. The dendritic cells from the skin present a part of the antigen to the lymph node dendritic cells. Once this occurs, the lymph nodes detect which molecules to sour in order to fight off the bacteria. This stage is also known as the mature stage because it contains the molecules require to stimulate the t- cell and the b-cell. Once the t-cell and b-cell are activated it turns on th1 and...If you ask to get a full essay, order it on our website: OrderCustomPaper.com
