Peyer's patch: Peyer's patches (or aggregated lymphoid nodules, or occasionally PP for brevity) are organized lymphoid nodules, named after the 17th-century Swiss anatomist Johann Conrad Peyer. They are aggregations of lymphoid tissue that are usually found in the lowest portion of the small intestine, the ileum, in humans; as such, they differentiate the ileum from the duodenum and jejunum.Inferior mesenteric lymph nodes: The inferior mesenteric lymph nodes consist of:Periarteriolar lymphoid sheaths: Periarteriolar lymphoid sheaths (or periarterial lymphatic sheaths, or PALS) are a portion of the white pulp of the spleen. 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.Polyclonal B cell response: Polyclonal B cell response is a natural mode of immune response exhibited by the adaptive immune system of mammals. It ensures that a single antigen is recognized and attacked through its overlapping parts, called epitopes, by multiple clones of B cell.Lymphotoxin beta receptor: Lymphotoxin beta receptor (LTBR), also known as tumor necrosis factor receptor superfamily member 3 (TNFRSF3), is a cell surface receptor for lymphotoxin involved in apoptosis and cytokine release. It is a member of the tumor necrosis factor receptor superfamily.Intraepithelial lymphocyte: Intraepithelial lymphocytes (IEL) are lymphocytes found in the epithelial layer of mammalian mucosal linings, such as the gastrointestinal (GI) tract and reproductive tract. However, unlike other T cells, IELs do not need priming.Tumor necrosis factors: Figure rendered using FirstGlance Jmol.Sectional Appendix: In Great Britain, the Sectional Appendix is a railway document compiled by Network Rail and is the official definition of railway infrastructure, giving a detailed description of all railway lines owned by Network Rail. It has traditionally been published in printed format, originally as a bound book and subsequently in loose-leaf format, for ease of updating.Lymphatic endothelium: The lymphatic endothelium is a specialised form of epithelium, distinct from but similar to vascular endothelium. A lymph capillary endothelial cell is distinct from other endothelial cells in that collagen fibers are directly attached to its plasma membrane.Osmotic controlled-release oral delivery system: OROS (Osmotic [Controlled] Release Oral [Delivery] System) is a controlled release oral drug delivery system in the form of a tablet. The tablet has a rigid water-permeable jacket with one or more laser drilled small holes.Addressin: Addressin also known as mucosal vascular addressin cell adhesion molecule 1 (MAdCAM-1) is a protein that in humans is encoded by the MADCAM1 gene.CXCL13: chemokine (C-X-C motif) ligand 13 (CXCL13), also known as B lymphocyte chemoattractant (BLC) or B cell-attracting chemokine 1 (BCA-1), is a protein ligand that in humans is encoded by the CXCL13 gene.Yersinia enterocolitica: Yersinia enterocolitica is a Gram-negative bacillus-shaped bacterium, belonging to the family Enterobacteriaceae. Y.PMHC cellular microarray: PMHC cellular microarrays are a type of cellular microarray that has been spotted with pMHC complexes peptide-MHC class I or peptide-MHC class II.Stratified squamous epithelium: A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.VenuleJejunumCorriedale: Corriedale sheep are a dual purpose breed, meaning they are used both in the production of wool and meat. The Corriedale is the oldest of all the crossbred breeds, a Merino-Lincoln cross developed almost simultaneously in Australia and New ZealandStock Types, The Land, North Richmond, c.List of diseases (Y): This is a list of diseases starting with the letter "Y".Lumbar lymph trunk: The lumbar trunks are formed by the union of the efferent vessels from the lateral aortic lymph glands.MicrovillusCDP-abequose synthase: CDP-abequose synthase (, rfbJ (gene)) is an enzyme with system name CDP-alpha-D-abequose:NADP+ 4-oxidoreductase. This enzyme catalyses the following chemical reactionAB5 toxin: The AB5 toxins are six-component protein complexes secreted by certain pathogenic bacteria known to cause human diseases such as cholera, dysentery, and hemolytic-uremic syndrome. One component is known as the A subunit, and the remaining five components make up the B subunit.CD19: B-lymphocyte antigen CD19 also known as CD19 (Cluster of Differentiation 19), is a protein that in humans is encoded by the CD19 gene. It is found on the surface of B-cells, a type of white blood cell.Germinal center B-cell like diffuse large B-cell lymphoma: Gene expression profiling has revealed that diffuse large B-cell lymphoma (DLBCL) is composed of at least 3 different sub-groups, each having distinct oncogenic mechanisms that respond to therapies in different ways. Germinal Center B-Cell like (GCB) DLBCLs appear to arise from normal germinal center B cells, while Activated B-cell like (ABC) DLBCLs are thought to arise from postgerminal center B cells that are arrested during plasmacytic differentiation.Haptotaxis: Haptotaxis (from Greek ἅπτω (hapto, "touch, fasten") and τάξις (taxis, "arrangement, order")) is the directional motility or outgrowth of cells, e.g.Acute myeloid dendritic cell leukemia: Acute myeloid dendritic cell leukemia is an exceedingly rare form of leukemia. This form of leukemia represents only about 0.ImmunizationField emission probes
