Analysis of Dendritic Cells in Patients With Acute or Chronic Skin Graft Versus Host Disease

Dendritic cells (DCs) serve as sentries for the immune system. DCs recognize foreign
compounds (antigens) in the body, which they internalize and process. When DCs uptake foreign
antigens, they migrate to secondary lymphoid organs, where the processed antigens are
presented to T cells.

Various DC subsets with unique cell lineages, surface protein markers, and tissue
localization determinants have been identified. For example, Langerhans cells (LCs) and
interstitial dendritic cells (intDCs) are DCs found in stratified epithelia, such as the
skin. Though both are expressed in the skin, they differ with respect to their origin and
surface protein content and can activate distinct types of immune responses. They may also
have different specificities for the capture of antigens and presentation to circulating T

To date, it is unknown what role, if any, the different DC populations that reside or
repopulate in the skin play in the development and progression of skin graft-versus-host
disease (GVHD) following bone marrow transplant.
