Welcome to More Choice CD Marker Handbook For more information, please visit: Human bdbiosciences.com/eu/go/humancdmarkers Mouse bdbiosciences.com/eu/go/mousecdmarkers Human and Mouse CD Marker Handbook Human and Mouse CD Marker Key Markers - Human Key Markers - Mouse CD3 CD3 CD (cluster of differentiation) molecules are cell surface markers T Cell CD4 CD4 useful for the identification and characterization of leukocytes. The CD CD8 CD8 nomenclature was developed and is maintained through the HLDA (Human Leukocyte Differentiation Antigens) workshop started in 1982. CD45R/B220 CD19 CD19 The goal is to provide standardization of monoclonal antibodies to B Cell CD20 CD22 (B cell activation marker) human antigens across laboratories. To characterize or “workshop” the antibodies, multiple laboratories carry out blind analyses of antibodies. These results independently validate antibody specificity. CD11c CD11c Dendritic Cell CD123 CD123 While the CD nomenclature has been developed for use with human antigens, it is applied to corresponding mouse antigens as well as antigens from other species. However, the mouse and other species NK Cell CD56 CD335 (NKp46) antibodies are not tested by HLDA. Human CD markers were reviewed by the HLDA. New CD markers Stem Cell/ CD34 CD34 were established at the HLDA9 meeting held in Barcelona in 2010.

Anti-CD40 Antibody KPL-404 Inhibits T Cell
Marken et al. Arthritis Research & Therapy (2021) 23:5 https://doi.org/10.1186/s13075-020-02372-z RESEARCH ARTICLE Open Access Anti-CD40 antibody KPL-404 inhibits T cell- mediated activation of B cells from healthy donors and autoimmune patients John Marken1, Sujatha Muralidharan2* and Natalia V. Giltiay1* Abstract Background: CD40-CD40L is a key co-stimulatory pathway for B cell activation. As such, its blockade can inhibit pathogenic B cell responses in autoimmune diseases, such as Sjogren’s syndrome (SjS) and systemic lupus erythematosus (SLE). In this study, we examined the in vitro effects of KPL-404, a humanized anti-CD40 monoclonal antibody (Ab), on primary human B cells derived from either healthy donors (HD) or autoimmune patients and compared them to the effects of G28-5, a partially antagonistic anti-CD40 antibody. Methods: PBMCs from HD or SjS and SLE patients were cultured in high-density cell cultures in the presence of IgG4 isotype control or anti-CD40 Abs KPL-404 or G28-5. Cells were stimulated with anti-CD3/CD28 cross-linking reagent ImmunoCult (IC) to induce CD40L-CD40-mediated B cell responses. B cell proliferation and activation, measured by dilution of proliferation tracker dye and the upregulation of CD69 and CD86, respectively, were assessed by flow cytometry. Anti-CD40 Ab cell-internalization was examined by imaging flow cytometry. Cytokine release in the PBMC cultures was quantified by bead-based multiplex assay. Results: KPL-404 binds to CD40 expressed on different subsets of B cells without inducing cell depletion, or B cell proliferation and activation in in vitro culture. -

In the last few years, identification of T cell activation markers to assess drug allergy has been the focus of several studies. Objective: The aim of the present work was to search for CD25 and CD69 markers on T CD4+ and T CD8+ cells in drug allergy. Methods: Fourteen patients with drug hypersensitivity were enrolled in this investigation. Some patients had at least one adverse reaction to one or more suspected drugs, therefore, a total of 16 reactions and 10 drugs were investigated. Prick or patch tests were done according with the time of onset and type of the clinical manifestations. -

A Novel CD4+ CTL Subtype Characterized by Chemotaxis and Inflammation Is Involved in the Pathogenesis of Graves’ Orbitopa
Cellular & Molecular Immunology www.nature.com/cmi ARTICLE OPEN A novel CD4+ CTL subtype characterized by chemotaxis and inflammation is involved in the pathogenesis of Graves’ orbitopathy Yue Wang1,2,3,4, Ziyi Chen 1, Tingjie Wang1,2, Hui Guo1, Yufeng Liu2,3,5, Ningxin Dang3, Shiqian Hu1, Liping Wu1, Chengsheng Zhang4,6,KaiYe2,3,7 and Bingyin Shi1 Graves’ orbitopathy (GO), the most severe manifestation of Graves’ hyperthyroidism (GH), is an autoimmune-mediated inflammatory disorder, and treatments often exhibit a low efficacy. CD4+ T cells have been reported to play vital roles in GO progression. To explore the pathogenic CD4+ T cell types that drive GO progression, we applied single-cell RNA sequencing (scRNA-Seq), T cell receptor sequencing (TCR-Seq), flow cytometry, immunofluorescence and mixed lymphocyte reaction (MLR) assays to evaluate CD4+ T cells from GO and GH patients. scRNA-Seq revealed the novel GO-specific cell type CD4+ cytotoxic T lymphocytes (CTLs), which are characterized by chemotactic and inflammatory features. The clonal expansion of this CD4+ CTL population, as demonstrated by TCR-Seq, along with their strong cytotoxic response to autoantigens, localization in orbital sites, and potential relationship with disease relapse provide strong evidence for the pathogenic roles of GZMB and IFN-γ-secreting CD4+ CTLs in GO. Therefore, cytotoxic pathways may become potential therapeutic targets for GO. 1234567890();,: Keywords: Graves’ orbitopathy; single-cell RNA sequencing; CD4+ cytotoxic T lymphocytes Cellular & Molecular Immunology -

These are primarily microbes (germs)—tiny, infection-causing Bacteria: organisms such as bacteria, viruses, streptococci parasites, and fungi. Because the human body provides an ideal environment for many microbes, they try to break in. It is the immune system’s job to keep them out or, failing that, to seek out and destroy them. Virus: When the immune system hits the wrong herpes virus target or is crippled, however, it can unleash a torrent of diseases, including allergy, arthritis, or AIDS. The immune system is amazingly complex. It can recognize and remember millions of Parasite: different enemies, and it can produce schistosome secretions and cells to match up with and wipe out each one of them. -

Immunological damage is mediated by a local Th2 inflammatory microenvironment, accompanied by changes in circulating cell subsets, with more effector cells and fewer T regulatory cells (Tregs). This study aimed to evaluate the involvement of toll-like receptor 4 (TLR4) and α-melanocyte stimulating hormone (α-MSH) in the immune regulation associated with perennial allergic conjunctivitis (PAC). We performed an Ag-specific stimulation during 72 h of culturing with or without lipopolysaccharide (LPS) or α-MSH in peripheral blood mononuclear cells (PBMC), analyzing the cell subsets and cytokines induced by the stimuli. -

Category: Cells Helper and Cytotoxic T cells Original author: Tracy Hussell, University of Manchester, UK UpdatedMelissa Bedard, by: Hannah MRC Jeffery,Human Immunology University of Unit, Birmingham University of Oxford T cells are so called because they are predominantly produced in the thymus. They recognise foreign particles (antigen) by a surface expressed, highly variable, T cell receptor (TCR). There are two major types of T cells: the helper T cell and the cytotoxic T cell. As the names suggest helper T cells ‘help’ other cells of the immune system, whilst cytotoxic T cells kill virally infected cells and tumours. Unlike antibody, the TCR cannot bind antigen directly. Instead it needs to have broken-down peptides of the antigen ‘presented’ to it by an antigen presenting cell (APC). The molecules on the APC that present the antigen are called major histocompatibility complexes (MHC). There are two types of MHC: MHC class I and MHC class II. MHC class I presents to cytotoxic T cells; MHC class II presents to helper T cells. The binding of the TCR to the MHC molecule containing the antigen peptide is a little unstable and so co-receptors are required. The CD4 co-receptor (left image, below) is expressed by helper T cells and the CD8 co-receptor (right image, below) by cytotoxic T cells. Although most T cells express either CD4 or CD8, some express both and proportion do not express either (“double negative” (DN)). Most T cells are defined as CD4 or CD8 but some are classified into additional types such as invariant Natural Killer T cells (iNKT), and Mucosal Associated Invariant T cells (MAIT) The TCR is made up of multiple chains to assist the transmission of the signal to the T cell.
