besides its long-known function as hair-producing organ, it is an immunologically active organ that shapes composition and function of immune cells within skin. In light of … Despite this, LCs display a remarkable mixture of Long-term antigen retention by dendritic cells in the popliteal lymph node of immunized mice. In contrast to other DCs, LCs arise from hematopoietic precursors that seed the skin before birth. NIH Relationship between macrophages, Langerhans cells, reticular cells, and dendritic cells in lymphoid and hematopoietic organs. Langerhans cells (LCs) are the dendritic cells (DCs) of the epidermis, forming one of the first hematopoietic lines of defense against skin pathogens. not well defined small-scale environment of a cell, usually encompassing the surrounding tissue and cells, in which a specific sphere of influence of other cells and molecules shapes the properties of this cell. Bone marrow: Reticulum cells. While macrophages are the core phagocytes and activators of the innate immune system, DCs represent a small population of hematopoietic antigen-presenting cells that have the unique ability to prime naïve T lymphocytes. Recent lineage-tracing studies have uncovered that rather than from bone marrow (BM)-derived DC precursors, adult mouse LCs are derived from embryonic yolk … properties.

Langerhans' cells and macrophages in eosinophilic granuloma Langerhans' cells and macrophages in eosinophilic granuloma Elema, J. D.; Atmosoerodjo‐Briggs, J. E. 1984-11-15 00:00:00 Biopsy material of six patients with eosinophilic granuloma (EG) was investigated by electron microscopic and enzyme-histochemical methods for acid phosphatase (AcP), leucyl-fi-naphthylamidase (LA), adenosine … Langerhans cells are generated by two distinct PU.1-dependent transcriptional networks. Phenotypic transformation of phagocytic dermal macrophages to Langerhans cells appears to represent a mechanism for repopulation of Langerhans cells during the period of immunologic reconstitution in this patient population. developmental history of a cell type within an organism, either during the whole lifetime of an organism or at a certain period of its development. of the dendritic cell (DC) lineage, they are now considered to be a specialized subset The paracortex mainly contains T cells while the cortex mainly contains B cells. In contrast to other DCs, LCs arise from hematopoietic precursors that seed the skin before birth. DCs share some properties with tissue macrophages. Langerhans cells protect from allergic contact dermatitis in mice by tolerizing CD8(+) T cells and activating Foxp3(+) regulatory T cells.
