The dendritic cells found in T cell areas of secondary lymphoid tissues are termed interdigitating cells. These cells are continually renewed by the influx into lymph nodes of veiled cells via the afferent lymph.

What are examples of dendritic cells?

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. They can also be found in an immature state in the blood.

What are the four types of dendritic cells?

In human, three DCs precursors are recognized: GMDPs, MDPs, and CDPs. As the cells differentiate, they acquire different phenotype. It is accepted that under the influence of Flt3-L, cDC1, cDC2, and pDCs originate from CDPs. In mouse, it has been shown that there are several precursors: CMPs, MDPs, and CDPs.
