Dendritic cells in lung immunopathology

Dendritic Cells in Transplant Tolerance

Dendritic cells (DCs) are a heterogeneous family of professional APCs involved in priming adaptive immune responses. Donor DCs (direct pathway of allorecognition) and recipient DCs presenting processed donor major histocompatibility complex (MHC) as peptides (indirect pathway of allorecognition) participate actively in graft rejection by stimulating recipient T cell responses following organ tr...

Plasmacytoid dendritic cells in angiolymphoid hyperplasia with eosinophilia

Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is characterized by irregularly-shaped blood vessels with an inflammatory infiltrate. While absent from normal skin, plasmacytoid dendritic cells (pDCs) infiltrate the skin upon injury and during several infectious, inflammatory, and neoplastic entities. In addition to providing anti-viral resistance, pDCs link the innate and adapti...

Dendritic Cells and Their Role in Cancer Immunotherapy

Dendritic cells (DCs) are antigen presenting cells with unique capability to take up and process antigens in the peripheral blood and tissues. They subsequently migrate to draining lymph nodes where they present these antigens and stimulate naive T lympho-cytes. During their life cycle, DCs go through two maturation stages and are referred to as immature and mature cells, respectively. While im...

Isolation of mouse lung dendritic cells.

Lung dendritic cells (DC) play a fundamental role in sensing invading pathogens (1,2) as well as in the control of tolerogenic responses (3) in the respiratory tract. At least three main subsets of lung dendritic cells have been described in mice: conventional DC (cDC) (4), plasmacytoid DC (pDC) (5) and the IFN-producing killer DC (IKDC) (6,7). The cDC subset is the most prominent DC subset in ...
