Dendritic Cells

Dendritic cells perform their daily tasks by acting as an antigen encloseing cell to efficiently introduce the antigen to separate immune cells direct in the body. The Dendritic cell activates when it come acrosss a harmful unlike substance in the body such as a bacteria, parasite, or viruses. Once the dendrite cell detects the strange substance it, it captures it and endows the antigen to the some other 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 cutis, lymph nodes, and the spleen. Dendritic cells are located in the kowtow and mucus passages, because a virus or orthogonal substance is most likely transmitted through these openings. The dendritic cells located on the skin are as intimately as know as the immature set, because of their low community of molecules (CD80, CD86,CD83).The dendritic cells in the immature stage basically plainly lay well-nigh until the immune system is invaded. Once a virus or bacteria enter the dendritic cells straightaway activate, but it is non mature abundant 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 to 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 indispensable 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: OrderEssay.net
