I mitten av epidermis i stratum spinosum finns de Langerhanska cellerna som i sin tur bildar ett fint nätverk som registrerar allt som passerar. De har långa armar (bläckfiskliknande) som sonderar terrängen. Ibland är sjukdomen livshotande. Celltypen som orsakar sjukdomen heter Langerhans celler, uppkallad efter den man som först påvisade dessa celler. På många sätt liknar histiocytos cancer, och sjukdomen behandlas också ofta av cancerläkare (onkologer) med cellgifter och strålning.

I denna artikel vill vi redogöra för den historiska bakgrunden till beskrivningen av sjukdomen och ge en uppdaterad syn på diagnos och kliniska symtom samt behandling av dessa patienter.
The cells were fluorescently stained with CD207 and CD11c and analyzed by … Langerhans cells (LCs) are epidermis-resident antigen-presenting cells that share a common ontogeny with macrophages but function as dendritic cells (DCs). Their development, recruitment and retention in the epidermis is orchestrated by interactions with keratinocytes through multiple mechanisms. De fleste steder på kroppen er epidermis kun 0,1 mm tyk. Dog kan det være væsentligt tykkere (ca. 1-5 mm.) på steder med meget slid, f.eks.
Langerhans cells (LCs) reside in the epidermis as a dense network of immune system sentinels.

identify in the zebrafish epidermis an ectoderm-derived immune cell type—metaphocytes—that capture soluble antigens from external environment through transepithelial protrusions and convey these antigens to conventional Langerhans cells via an apoptosis-phagocytosis pathway. 1967-09-01 Multifocal Langerhans cell sarcoma involving epidermis: a case report and review Changsong Wang1*, Yanping Chen1, Chunfang Gao1, Jian Yin1 and Hong Li2 Abstract Objective: To study the clinico-pathological characteristics of Langerhans cell sarcoma (LCS) which involving epidermis. Langerhans cells which represent 3-6% of all cells in the epidermis, are mobile, dendritic, antigen presenting cells with a stellate appearance which reside in the suprabasal layers of the epidermis wedged in between, and in close contact with keratinocytes.

De aktiverade cellerna stimulerar T-lymfocyterna. With epidermotropic migration, Langerhans cell precursors undergo phenotypic and functional maturation (green to red transition), and as a consequence of replication, altered adhesion, or dysregulated chemokine networks, accumulate as LCM in the upper epidermal layers.

AB - In addition to the keratinocytes, the epidermis contains resident cells of dendritic morphology. These are principally the Langerhans cell, Merkel cell and melanocyte. Langerhanscellen (of: cellen van Langerhans) zijn dendritische (vertakte) cellen in de huid, die een belangrijke rol spelen bij het immuunsysteem.Bij een binnendringing van de huid nemen de langerhanscellen antigenen van de binnendringers op en reizen naar een lymfeknoop waar ze de antigenen aanbieden aan nog ongespecialiseerde T1-cellen. A slightly reduced population of Langerhans' cells is located in the epidermis of 80% of the nodules, occasionally showing a concentration in the pronounced epidermal ridges. Twenty percent of the nodules possess an epidermis which is completely free of Langerhans' cells. langerhans cell In this issue of Blood , Martínez-Cingolani et al identified that human thymic stromal lymphopoietin (TSLP), previously shown to be induced during skin inflammation, stimulates myeloid-related BDCA-1 + peripheral blood dendritic cells (DCs) to rapidly gain phenotypic characteristics of human epidermal Langerhans cells (LCs).
