| histiocytosis, non-langerhans-cell | Group of disorders which feature accumulations of active histiocytes and lymphocytes, but where the histiocytes are not langerhans cells. The group includes haemophagocytic lymphohistiocytosis, infection-associated haemophagocytic syndrome, sinus histiocytosis, xanthogranuloma, reticulohistiocytoma, juvenile xanthoma, xanthoma disseminatum, as well as the lipid storage diseases (sea-blue histiocyte syndrome and niemann-pick disease). (12 Dec 1998) |

| histiocytosis, sinus | Benign, non-langerhans-cell, histiocytic proliferative disorder that primarily affects the lymph nodes. It is often referred to as sinus histiocytosis with massive lymphadenopathy. (12 Dec 1998) |
| histiogenic | Formed by the tissues; e.g., the histogenous cells in an exudate arising from proliferation of the fixed tissue cells. Synonym: histiogenic. Origin: histo-+ G. -gen, producing (05 Mar 2000) |
| histioid | 1. Resembling in structure one of the tissues of the body. 2. Sometimes used with reference to the histologic structure of a neoplasm derived from and consisting of a single, relatively simple type of neoplastic tissue that closely resembles the normal, as in certain fibromas and leiomyomas. Synonym: histioid. Origin: histo-+ G. Eidos, resemblance (05 Mar 2000) |
| histiology | <study> Same as Histology. Origin: Gr. "istos tissue. Source: Websters Dictionary (01 Mar 1998) |
| histioma | <oncology, tumour> A histoma is any tumour which was derived from mature tissue. (09 Oct 1997) |
| histionic | Relating to any tissue. (05 Mar 2000) |
| histo- | Tissue. Origin: G. Histos, web (tissue) (05 Mar 2000) |
| histo-blood group B transferase | <enzyme> Catalyses transfer of galactose from udp-galactose to glycoproteins and glycolipids; differs from a transferase by four amino acid residues Registry number: EC 2.4.1.- Synonym: b transferase, histo-blood group (26 Jun 1999) |
| histoangic | Relating to the structure of blood vessels, especially in terms of their function. Synonym: histangic. Origin: histo-+ G. Angeion, vessel (05 Mar 2000) |
| histoblast | Population of small diploid epithelial cells in Dipteran larvae that do not form typical imaginal discs, yet resemble them in some ways. (18 Nov 1997) |
| histochemistry | Study of the chemical composition of tissues by means of specific staining reactions. (18 Nov 1997) |
| histocompatibility | If tissues of two organisms are histocompatible, then grafts between the organisms will not be rejected. If, however, major histocompatibility antigens are different then an immune response will be mounted against the foreign tissue. (18 Nov 1997) |
| histocompatibility antigen | <immunology> A set of plasmalemmal glycoproteins on the surface of all nucleated cells that are crucial for T-cell recognition of antigens. Particularly the HLA system in humans and the H2 system in mice. They are the major antigens responsible for tissue recognition. For this reason, they are of prime importance in determining compatible organ donors for a specific transplantation procedure. Each person has unique HLA antigens. Some HLA antigens have been identified to be correlated with the presence of certain autoimmune diseases. One of these is the HLA-B27 site. Approximately 85% of patients with ankylosing spondylitis and Reiter's syndrome will have the HLA-B27 antigen present on the leukocytes. There are two classes of histocompatibility antigens: 1. Class I, histocompatibility antigens composed of two glycosylated subunits, a heavy chain of 44 kD and beta2 microglobulin (12 kD). The heavy chain may be coded by K, D or L genes of mouse H2 and A, B or C genes of human HLA complex. Class I antigens are important in T-cell killing and are recognised in conjunction with the foreign cell surface antigens MHC restriction). 2. Class II antigens, heterodimeric histocompatibility antigens composed of alpha (32 kD) and beta (28 kD) chains. Found mostly on B lymphocytes, macrophages and accessory cells. The response of T helper cells requires that the foreign antigen is presented in conjunction with the appropriate Class II antigens. (Murine H2 Ia antigens and human HLA DR antigens are Class II). (14 Oct 1997) |
| histocompatibility antigens | A group of antigens that includes both the major and minor histocompatibility antigens. The former are genetically determined by the major histocompatibility complex. They determine tissue type for transplantation and cause allograft rejections. The latter are systems of allelic alloantigens that can cause weak transplant rejection. (12 Dec 1998) |
