Refimprove date July 2007 Target cell is a term given to one of three different concepts in medicine. Hematology In hematology , target cells are very abnormal red blood cells , that have a bullseye target bullseye appearance See main article codocyte . These target cells from red blood cells are associated with Hemoglobin C HbC disease, Asplenia , Liver Disease , Thalassemia and severe Iron deficiency anemia . Target cells may be seen on a peripheral blood smear when there is excess membrane relative to the amount of hemoglobin. Membrane may be excessive in liver disease. Intracellular hemoglobin may be lowered during iron deficiency, thalassemia, hemoglobin C or SC and other hemoglobinopathies. Immunology In immunology , target cells are cells which present the antigen antigenic peptide combined with MHC class I molecules to Cytotoxic T cell s. These cells have MHC molecules on their surface in contrast to AntigenPresentingCell s, which in addition also have MHC class II molecules . Target Cells are the normal cells of the body which have undergone some alteration and synthesize abnormal proteins e.g. tumor cells, virus infected cells. Endocrinology In endocrinology , target cells can refer to the cells where hormone s have their effect. Target cells are capable of responding to hormones because they bear Receptor biochemistry receptors to which the hormone can bind. Most hormones circulate in blood, coming into contact with essentially all cells. However, a given hormone usually affects only a limited number of cells, which are called target cells. A target cell responds to a hormone because it bears receptors for the hormone. Hormone receptors are found either exposed on the surface of the cell or within the cell, depending on the type of hormone. A hormone may bind target cells in three general ways Endocrine action the hormone is distributed in blood and binds ... cells in the neighborhood. Autocrine action the hormone acts on the same cell that produced it. Category ... more details
Lymphocyte function associated antigen 1 , also known as LFA 1 is found on all T cells and also on B cells , macrophages and neutrophils and is involved in recruitment to the site of infection. It binds to ICAM 1 on antigenpresenting cells and functions as an adhesion molecule. LFA 1 is the first to bind T cells to antigenpresenting cells and initially binds weakly. A signal from the T cell receptor and or the cytokine receptor changes the conformation and prolongs the cell contact, allowing the T cell to proliferate. LFA 1 is part of the family of leukocyte integrin s that are recognised by their common chains CD18 . LFA 1 also has a distinct chain CD11a .

The Lewis antigen system is a Human blood group systems human blood group system based upon genes on chromosome 19 p13.3 FUT3 or Lewis gene and 19q13.3, FUT2 or secretor gene . Both genes are expressed in glandular epithelia and have dominant alleles Le and Se, respectively coding for enzymes with fucosyltransferase activity and recessive alleles le and se, respectively that are not functional. There are two main types of Lewis antigens, Lewis a Le a and Lewis b Le b . They are red cell antigens which are not produced by the erythrocyte itself.

The band 3 protein functions in the transport of chlorine ions and carbonate . The resulting factor of each SLC4A1 allele is classified as a separate Human blood group systems blood group . Diego antigens are only found or in some cases, only not found in populations of Aboriginal American s in both North and South America and the Mongolic peoples of East, Southeast, North Central and Northeast Asia.

History and occurrence The Diego and Wright antigen s were thought to be separate systems until 1992, when it was realised they were part of one system. The labeling of individual factors, however, has not changed, with the former Wright factors still signed Wr while the rest of the Diego factors are signed Di .

Otheruses2 Biomarker A biomarker can be understood as a molecule that is present or absent from a particular cellular type. This facilitates the characterization of a cell type, their identification, and eventually their isolation. Cell sorting techniques are based on cellular biomarkers for example, Fluorescent activated cell sorting . A biomarker can be used to identify a cell population, make a diagnostic , measure the progress of disease or the effects of treatment. ref http www.medterms.com script main art.asp?articlekey 6685 Medterms definition ref One example of cellular biomarker is the protein Oct 4 that is found in embryonic stem cell s, while the Carcinoembryonic antigen CEA is a tumoral marker used to follow up cancer treatment, and the Prostate Specific Antigen PSA is used for diagnostic. ref http www.questdiagnostics.com kbase topic medtest hw3988 consider.htm Quest diagnostic ref References reflist Cell biology stub Category Cell biology ... more details
