MICROBIOLOGY: Dendritic Cells, Part 2

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...

Dendritic cells in experimental renal inflammation--Part I.

Dendritic cells (DCs) are bone marrow-derived professional antigen-presenting cells that act as master regulators of acquired and innate immune responses. While descriptions of cells with dendritic morphology in rodent kidneys date back to the early 1970s, a network of DCs in the mouse kidney has only recently been described. DCs acquire distinct phenotypic and functional characteristics depend...

Dendritic cells in human renal inflammation--Part II.

Dendritic cells (DCs) are bone marrow-derived professional antigen-presenting cells that act as master regulators of acquired and innate immune responses. Here, we review the available information on their role in human renal inflammation. In the 1980s and early 1990s, major histocompatibility complex class II antigen- (HLA-DR) positive DCs were first described in normal human kidneys and in th...

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...
