Langerhans Cell - an overview ScienceDirect Topic

  1. Langerhans cells constitute the first line of immunologic defense in the skin [10]. These cells are derived from the bone marrow and can normally be found scattered among the keratinocytes of the stratum spinosum. 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
  2. A Langerhans cell is a specific kind of white blood cell. Found largely in the epidermis, the outer layer of the skin, as well as in lymph nodes, Langerhans cells are an important element of the immune system. They are classified as dendritic cells because they grow projections called dendrites as they develop. Langerhans cells work to prevent infections, and they help trigger immune reactions by interacting with T-cells
  3. Langerhans cell definition is - a cell found in the epidermis that functions as an antigen-presenting cell which binds antigen entering through the skin
  4. One of these rare disorders -- which resembles some types of cancer-- is called Langerhans cell histiocytosis, or LCH. It most commonly appears in toddlers and very young children, but you can.

The islets of Langerhans contain alpha, beta, and delta cells that produce glucagon, insulin, and somatostatin, respectively. A fourth type of islet cell, the F (or PP) cell, is located at the periphery of the islets and secretes pancreatic polypeptide. These hormones regulate one another's secretion through paracrine cell-cell interactions The representation of Langerhans cells in the Cell Ontology. A portion of the Cell Ontology is shown with ovals corresponding to cell types defined in the ontology and arrows corresponding to relations between those cell types. From Masci et al., 2009 Other articles where Langerhans cell is discussed: integument: Skin structure: cell types: Merkel cells and Langerhans cells. Merkel cells form parts of sensory structures. Langerhans cells are dendritic but unpigmented and are found nearer the skin surface than melanocytes. After a century of question about their purpose, it is now clear that they have a vital immunologic function Langerhans cell histiocytosis (LCH) is a rare multisystem disease with a wide and heterogeneous clinical spectrum and variable extent of involvement. Terminology Langerhans cell histiocytosis was previously known as histiocytosis X. The newer.

Langerhans cell histiocytosis is a clonal proliferation of cells that morphologically and immunophenotypically resemble Langerhans cells More common in childhood (1 - 3 years old) and involves nodal and extranodal sites (most common site is bone 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). LC acquire antig The immune system contains cells called histiocytes. Langerhans' cells are a specific type of histiocyte that help fight infection in the skin. When a child has LCH, these cells spread through the bloodstream to other healthy parts of the body where they can cause damage. LCH can be divided into two groups

Langerhans cell histiocytosis (LCH) is a group of idiopathic disorders characterized by the presence of cells with characteristics similar to bone marrow-derived Langerhans cells juxtaposed against a backdrop of hematopoietic cells, including T-cells, macrophages, and eosinophils. In 1868, Paul Langerhans discovered the epidermal dendritic ce.. Langerhans' cell: dendritic cell in the skin that functions in the processing of antigen. See also dendritic cell Langerhans cell histiocytosis is an abnormal clonal proliferation of Langerhans cells, abnormal cells deriving from bone marrow and capable of migrating from skin to lymph nodes. Symptoms range from isolated bone lesions to multisystem disease. Symptoms range from isolated bone lesions to multisystem disease. LCH is part of a group of syndromes called histiocytoses, which are characterized by an abnormal proliferation of histiocytes. These diseases are related to other forms of abnormal prolife Langerhans cell histiocytosis (LCH) is a group of rare, idiopathic disorders which can cause damage to the skin, bones and other organs. An overload of cells similar to LCs are produced in this disorder, however, LCH cells show a different, hematopoietic (blood cells) origin for the disorder

Langerhans cell histiocytosis (also called histiocytosis X) is a rare disorder that primarily affects children. This disorder is characterized by an abnormal increase in certain immune cells called histiocyte cells. Histiocyte cells are a form of white blood cells that help the immune system destroy foreign materials and fight infection 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. In people with LCH, these cells multiply excessively and.

Langerhans Cell Histiocytosis (LCH): Symptoms, Causes

Langerhans cell histiocytosis is a rare disorder that damages tissues all over the body. It occurs when your child has very high levels of a type of immune cell (Langerhans cell). The extra cells travel all over the body. The cells build up and create tumors. These tumors can be in areas such as the skin, bones, bone marrow, lymph nodes, mouth. Langerhans Cell Histiocytosis (LCH) is a collection of rare disorders of the mononuclear phagocytes and dendritic cells. 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 are immune cells that are normally found within the epidermis where they act as antigen-presenting cells in an early warning system fighting foreign material such as bacteria. They may migrate to the local lymph glands but usually return to the skin Langerhans cells function similarly in human and mouse and can be identified by the presence of Langerin/CD207-containing Birbeck granules. Both human and mouse Langerhans cells express MHC class II, E-Cadherin, EpCAM/TROP1, Integrin alpha X/CD11c, and Langerin/CD207 Langerhans' cell histiocytosis (LCH) is a rare clonal disorder of proliferating histiocytic cells expressing phenotypic markers of the epidermal Langerhans' cells.
