They are populated largely by T cells and surround central arteries within the spleen; the PALS T-cells are presented with blood borne antigens via myeloid dendritic cells.Cell-mediated immunity: Cell mediated immunity is an immune response that does not involve antibodies, but rather involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen. Historically, the immune system was separated into two branches: humoral immunity, for which the protective function of immunization could be found in the humor (cell-free bodily fluid or serum) and cellular immunity, for which the protective function of immunization was associated with cells.CTL-mediated cytotoxicityThymidine diphosphateSister (Sister2Sister song)Micronucleus test: A micronucleus test is a test used in toxicological screening for potential genotoxic compounds. The assay is now recognized as one of the most successful and reliable assays for genotoxic carcinogens, i.Flow cytometry: In biotechnology, flow cytometry is a laser-based, biophysical technology employed in cell counting, cell sorting, biomarker detection and protein engineering, by suspending cells in a stream of fluid and passing them by an electronic detection apparatus. It allows simultaneous multiparametric analysis of the physical and chemical characteristics of up to thousands of particles per second.Hassall's corpuscles: Hassall's corpuscles (or thymic corpuscles (bodies)) are structures found in the medulla of the human thymus, formed from eosinophilic type VI epithelial reticular cells arranged concentrically. These concentric corpuscles are composed of a central mass, consisting of one or more granular cells, and of a capsule formed of epithelioid cells.HLA B7-DR15-DQ6MinC: The MinC protein is one of three proteins encoded by the minB operon and which is required to generate pole to pole oscillations prior to bacterial cell division as a means of specifying the midzone of the cell. This function is achieved by preventing the formation of the divisome Z-ring around the poles.Helichrysum petiolare: Helichrysum petiolare, known as licorice or liquorice plant, silver bush everlasting flower, trailing dusty miller and kooigoed, is a species of flowering plant in the family Asteraceae, native to South Africa and introduced to Portugal and the United States of America.Genetic imbalance: Genetic imbalance is to describe situation when the genome of a cell or organism has more copies of some genes than other genes due to chromosomal rearrangements or aneuploidy.KLRD1: CD94 (Cluster of Differentiation 94), also known as killer cell lectin-like receptor subfamily D, member 1 (KLRD1) is a human gene.Monoclonal antibody therapyCryptic self epitopes: In immunology, cryptic self epitopes are a source of autoimmunity.Immunogenetics (journal): Immunogenetics is a peer-reviewed scientific journal covering immunogenetics, the branch of medical research that explores the relationship between the immune system and genetics. This journal publishes original research papers, brief communications and reviews in: immunogenetics of cell interaction, immunogenetics of tissue differentiation and development, phylogeny of alloantigens and of immune response, genetic control of immune response and disease susceptibility, and genetics and biochemistry of alloantigens.Mutagen: In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingHistory and naming of human leukocyte antigens: Human leukocyte antigens (HLA) began as a list of antigens identified as a result of transplant rejection. The antigens were initially identified by categorizing and performing massive statistical analyses on interactions between blood types.Suppressor-inducer T cell: Suppressor-inducer T cells are a specific subset of CD4+ T helper cells that "induce" CD8+ cytotoxic T cells to become "suppressor" cells. Suppressor T cells are also known as CD25+–Foxp3+ regulatory T cells (nTregs), and reduce inflammation.Inferior mesenteric lymph nodes: The inferior mesenteric lymph nodes consist of:CD36 antigen: CD36 antigen is a transmembrane, highly glycosylated, glycoprotein expressed by monocytes, macrophages, platelets, microvascular endothelial cells and adipose tissues. CD36 recognises oxidized low density lipoprotein, long chain fatty acids, anionic phospholipids, collagen types I, IV and V, thrombospondin and Plasmodium falciparum infected erythrocytes.Kinetic-segregation model of T cell activationT helper 3 cell: T helper 3 cells are a type of T helper cell, lymphocytes involved in regulating the immune response.T helper cells in general mediate the immune response by secreting cytokines and interacting with B-cells to enhance or inhibit their activity.Tingible body macrophage: A tingible body macrophage is a type of macrophage predominantly found in germinal centers, containing many phagocytized, apoptotic cells in various states of degradation, referred to as tingible bodies (tingible meaning stainable).Horst Ibelgaufts' COPE: Cytokines & Cells Online Pathfinder Encyclopaedia > tingible body macrophages Retrieved on June 27, 2010 Tingible body macrophages contain condensed chromatin fragments.Immunosuppression: Immunosuppression is a reduction of the activation or efficacy of the immune system. Some portions of the immune system itself have immunosuppressive effects on other parts of the immune system, and immunosuppression may occur as an adverse reaction to treatment of other conditions.Immunophenotyping: Immunophenotyping is a technique used to study the protein expressed by cells. This technique is commonly used in basic science research and laboratory diagnostic purpose.DNA condensation: DNA condensation refers to the process of compacting DNA molecules in vitro or in vivo.
