Langerhans cell histiocytosis is a disorder in which excess immune system cells called Langerhans cells build up in the body. Langerhans cells, which help regulate the immune system, are normally found throughout the body, especially in the skin, lymph nodes, spleen, lungs, liver, and bone marrow. Langerhans' cells are white blood cells in the immune system that normally play an important role in protecting the body against viruses, bacteria and other invaders. They are found in the skin, lymph nodes, spleen, bone marrow and lungs.

Other disorders similar to LCH include Histiocytoses Rosai-Dorfman, juvenile xanthogranuloma, and Erdheim-Chester disease but they do not share the exact phenotypic signature of LCH. Langerhans cells (LCs) reside in the epidermis as a dense network of immune system sentinels. These cells determine the appropriate adaptive immune response (inflammation or tolerance) by interpreting the microenvironmental context in which they encounter foreign substances. In a normal physiological, “non-dangerous” situation, LCs coordinate a continuous state of immune tolerance Langerhans cells makes up 3–5% of the cells in the stratum spinosum [4]. Langerhans cells and melanocytes are connected to adjacent cells by desmosomes the same way keratinocytes are connected to one another.

Langerhans celler är antigenpresenterande dendritiska celler, vilket innebär att de är celler som normalt presenterar främmande ämnen (antigener) för vissa celler i immunsystemet. Förekomst Det årliga insjuknandet (incidensen) har uppskattats till 9 per miljon barn under 15 års ålder. 5 rows 2017-09-11 Langerhans cells (LC) are members of the dendritic cells family, residing in the basal and suprabasal layers of the epidermis and in the epithelia of the respiratory, digestive and urogenital tracts. They specialize in antigen presentation and belong to the skin immune system (SIS).

Vote(s) Species Official gene symbol UI Sensitivity (human) Sensitivity … Langerhans cells are dendritic cells of monocyte-macrophage lineage, containing large granules called Birbeck granules.They are normally found in epithelial surfaces, lymph nodes and other organs, and can also be found elsewhere, particularly in association with Langerhans cell histiocytosis..

Author information: (1)Department of Human Anatomy and Histology, V. le G.Pieraccini, Firenze, Italy. Skin biopsies from Langerhans cells (LCs) are epidermal immune cells of myeloid origin. Although these cells were primarily thought to play a defensive role in the skin, evidence now indicates a diverse range of LC‐mediated effects including the relay of viral antigens in herpes simplex infection, recruitment of eosinophils in atopic dermatitis and promotion of a Th17 response in Candida infection.

Our assumptions on the identity and functions of Langerhans cells (LCs) of the epidermis have undergone considerable changes. Once thought to be prototypic representatives of the dendritic cell (DC) lineage, they are now considered to be a specialized subset of tissue-resident macrophages. Despite this, LCs display a remarkable mixture of properties. Langerhans cells, along with other classes of dendritic cells, are universally found in all skin,. There is minimal variation between parts of the body in their content of Langerhans cells.
