The identity of Langerhans cells (LCs) has been called into question of late due to the increasing evidence that LCs originate from macrophage lineage instead of dendritic cell (DC) lineage as previously thought. For many years, LCs have been assumed to be DCs due to its migratory capabilities. However, recent studies have demonstrated that LCs are from macrophage lineage of the adult fetal

Langerhans cells are derived from a mobile pool of bone marrow -derived precursors and constitute, in normal epidermis, a stable self 2021-03-30 2001-09-01 Definition (GO) A cell-cell junction in which: on the cytoplasmic surface of each interacting plasma membrane is a dense plaque composed of a mixture of intracellular anchor proteins; a bundle of keratin intermediate filaments is attached to the surface of each plaque; transmembrane adhesion proteins of the cadherin family bind to the plaques and interact through their extracellular domains to OSTI.GOV Journal Article: Langerhans cell number and morphology in mouse footpad epidermis after X irradiation Langerhans Cell is a type of dendritic cell of the epidermis. 1 Appearance 2 Personality 3 Background 3.1 History 4 Abilities In his debut appearance, Langerhans Cell is depicted as a bearded man with a pair of glasses and a dinner jacket/tuxedo; resembling a butler. Langerhans cell granules contained characteristic mid-line lin defmite demonstration of Langerhans cells in bovine epidermis. Langerhans cells were positively identified in the epidermis of cattle using the ultrastructural criteria established by Birbeck, Breathnach, and Everall [8]. Langerhans cells (LCs) are bone marrow-derived dendritic cells (DCs) that represent 2-3% of the entire cell population of the human skin, known to have an ability to present antigens to T lymphocytes. Moreover, there is evidence that LCs are probably capable of inducing the local cytotoxic type T-cell-mediated response against the tumour-associated antigens.

Langerhans cells, which account for 3–8 percent of the cells in the epidermis, are most common in the superficial portion of the stratum spinosum. These cells play an important role in triggering an immune response against epidermal cancer cells and pathogens that have penetrated the superficial layers of the epidermis. Langerhans cell histiocytosis (LCH) is a disorder that primarily affects children, but is also found in adults of all ages. People with LCH produce too many Langerhans cells or histiocytes, a form of white blood cell found in healthy people that is supposed to protect the body from infection. Langerhans cells 4.

2014-02-15 2017-09-11 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.

The Langerhans cell tumors were classified into Langerhans cell histiocytosis (LCH) and Langerhans cell sarcoma (LCS) by the World Health Organization (WHO) in 2001. LCS is a rare dendritic cell tumor, and the WHO defined it as having typical features of malignant cytology as a high-grade variant of LCH.
