  • molecular
  • Conversely, under other circumstances CD34 has been shown to act as molecular "Teflon" and block mast cell, eosinophil and dendritic cell precursor adhesion, and to facilitate opening of vascular lumina. (wikipedia.org)
  • neuronal
  • Giant cell glioblastoma and pleomorphic xanthoastrocytoma show different immunohistochemical profiles for neuronal antigens and p53 but share reactivity for class III beta-tubulin. (nih.gov)
  • chemokine
  • Finally, recent data suggest CD34 may also play a more selective role in chemokine-dependent migration of eosinophils and dendritic cell precursors. (wikipedia.org)
  • cells
  • A concurrent patient group meeting eligibility but not receiving CD34+ cells will be evaluated similar to the treated group to assess the rate of significant spontaneous improvement in cardiac function without CD34+cell infusion. (bioportfolio.com)

  • The presence of CD34 on non-hematopoietic cells in various tissues has been linked to progenitor and adult stem cell phenotypes. (wikipedia.org)
  • citation needed] CD34 is expressed in roughly 20% of murine hematopoietic stem cells, and can be stimulated and reversed. (wikipedia.org)
  • The Fc region of immunoglobulin E (IgE) becomes bound to mast cells and basophils and when IgE's paratopes bind to an antigen, it causes the cells to release histamine and other inflammatory mediators. (wikipedia.org)
  • The Duffy antigen is located on the surface of red blood cells, and is named after the patient in which it was discovered. (wikipedia.org)
  • It was originally named theta (θ) antigen, then Thy-1 (THYmocyte differentiation antigen 1) due to its prior identification in thymocytes (precursors of T cells in the thymus). (wikipedia.org)
  • T cells become activated by recognising foreign antigens bound to antigen presenting cells (APC), in particular, dendritic cells. (wikipedia.org)
  • In order for naïve T cells to bind to their specific antigen, they need to experience physical contact with those cells. (wikipedia.org)
  • Therefore, T cells need a region where they can go to sample foreign antigens that have entered the body. (wikipedia.org)
  • gene
  • The Duffy antigen gene was the fourth gene associated with the resistance after the genes responsible for sickle cell anaemia, thalassemia and glucose-6-phosphate dehydrogenase. (wikipedia.org)
  • The gene was first localised to chromosome 1 in 1968, and was the first blood system antigen to be localised. (wikipedia.org)
  • encounter
  • When they encounter such an antigen, the cell becomes activated, resulting in the immune system mounting a response against the causative agent of the infection. (wikipedia.org)
  • ELISA
  • MA5-17829 targets CD34/gp105-120 in ELISA, FACS, IHC (F), IHC (P), IP, and WB applications and shows reactivity with Mouse samples. (thermofisher.com)
  • Functions
  • Effector memory T-lymphocytes do not express L-selectin, as they circulate in the periphery and have immediate effector functions upon encountering antigen. (wikipedia.org)
  • express
  • Central memory T-lymphocytes, which have encountered antigen, express L-selectin to localize in secondary lymphoid organs. (wikipedia.org)
  • expression
  • BRAF-mutated pleomorphic xanthoastrocytoma is associated with temporal location, reticulin fiber deposition and CD34 expression. (nih.gov)
  • Blood
  • It carries the antigenic determinants of the Duffy blood group system which consist of four codominant alleles-FY*A and FY*B-coding for the Fy-a and Fy-b antigens respectively, FY*X and FY*Fy, five phenotypes (Fy-a, Fy-b, Fy-o, Fy-x and Fy-y) and five antigens. (wikipedia.org)
  • Since antigen levels are usually low, contact in blood circulation would be unlikely. (wikipedia.org)
  • Structure
  • Three-dimensional structure prediction of the interaction of CD34 with the SH3 domain of Crk-L. (abnova.com)
  • negative
  • A negative CD34 may exclude Ewing's sarcoma/PNET, myofibrosarcoma of the breast, and inflammatory myofibroblastic tumors of the stomach. (wikipedia.org)
  • Molecular
  • Conversely, under other circumstances CD34 has been shown to act as molecular "Teflon" and block mast cell, eosinophil and dendritic cell precursor adhesion, and to facilitate opening of vascular lumina. (wikipedia.org)

  • The processes of beta-selection, positive selection, and negative selection shape the population of thymocytes into a peripheral pool of T cells that are able to respond to foreign pathogens and are immunologically tolerant towards self antigens. (wikipedia.org)
  • The ability of T cells to recognize foreign antigens is mediated by the T cell receptor (TCR), which is a surface protein able to recognize short protein sequences (peptides) that are presented on MHC. (wikipedia.org)
  • It has been shown that these pre-endothelial/pre-hematopoietic cells in the embryo arise out of a phenotype CD34 population. (wikipedia.org)
  • The hypothesis of a bipotential precursor was further supported by the fact that endothelial cells and hematopoietic cells share many of the same markers, including Flk1, Vegf, CD34, Scl, Gata2, Runx1, and Pecam-1. (wikipedia.org)
