It is easy to be fascinated by dendritic cells DCs not only because of their pivotal role in the immune response but also because of the elegance with which they perform their tasks. 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.
DCs can take up a diverse array of antigens and present them to T cells.

Epidermal Dendritic Cells. Epidermal or dermal dendritic cells are found in different forms on and within the skin. All epidermal dendritic cells activate T-cells on or in the epidermis and dermis.
One example is the Langerhans cell LC. Langerhans cells migrate to the lymph nodes from the skin bringing an antigen with them to present to a naïve T cell. They are highly specialized for processing foreign protein antigens.
In the mature state they efficiently stimulate resting antigen-specific T cells. Dendritic cells can migrate from the non-lymphoid tissues where they reside in the immature state via the afferent lymphatics or the blood to the T. Dendritic cells are highly specialized accessory cells for the initiation of primary immune responses.
They occur as trace populations in non-lymphoid and lymphoid organs. Therefore the isolation and enrichment of primary dendritic cells is difficult and time-consuming. A dendritic or Langerhan cell is a specialized _____.
Activated antigen-specific T cells migrate to the injured tissue. Th cells secretecytokines which permit activationof macrophages eosinophils and NK cells. CTLs eventuallylyse these cells.
In parallel B cells become activated after contact with T cells and DC. They migrate into specialized. It is easy to be fascinated by dendritic cells DCs not only because of their pivotal role in the immune response but also because of the elegance with which they perform their tasks.
Although DCs comprise multiple subsets Liu 2001 this issue of Cell all are unusually effective at antigen processing and presentation. DCs can take up a diverse array of antigens and present them to T cells. The dendritic cells they are a heterogeneous group of hematopoietic cells which play an important role in innate immunity and adaptive immunity.
They are cells that are responsible for detecting phagocytose and presenting the toxins or pathogens antigens that enter the body. Dendritic cells perform their function very efficiently which is why they are known as professional antigen. Langerhans cells LCs are specialized dendritic cells DCs strategically located in stratified epithelia such as those of the skin oral cavity pharynx esophagus upper airways urethra and.

Specialized intraepithelial lymphocytes IEL reside at sites where the bodys surface is at the interface with the external environment such as the epidermis or mucosa.
Mouse epidermis contains large numbers of such prototypic IEL called dendritic epidermal T cells DETC.
