CD10
CD11
  • Alpha component of various integrins (CD11a, CD11b, CD11c, CD11d)
  • Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain
  • Adhesion molecules of the beta2 integrin family (CD11 / CD18) plays an essential role in neutrophil recruitment and activation during inflammation
  • Clinical features: deficiency of CD18 component (leukocyte adhesion deficiency) is a rare, inherited disorder, causing recurrent severe bacterial infections early in life, possibly fatal (OMIM: 116920 [Accessed 10 May 2021], Hematol Oncol Clin North Am 1988;2:13)
CD11a
  • Alpha integrin chain at 16p11-13.1 that binds to CD18 and has various leukocyte functions (OMIM: 153370 [Accessed 10 May 2021])
  • Also called integrin alpha L, ITGAL and LFA1 alpha chain (in complex with CD18)
  • Pathophysiology:
    • Alpha integrin chain which binds to CD18 and mediates leukocyte adhesion to endothelium, leukocyte trafficking through activated endothelium, lymphocyte blastogenesis, lymphocyte endothelial cell adhesion, lymphocyte recirculation through lymph nodes, cytotoxic T cell mediated killing and antibody dependent killing by neutrophils and monocytes
    • Also mediates binding to unopsonized bacteria (e.g. E. coli) and fungi (e.g. Histoplasma capsulatum)
    • With CD18, binds to ICAM1 (CD54), ICAM2 (CD102), ICAM3 (CD50) and ICAM4 (CD242)
    • CD11a identifies effector and memory CD8+ T cells, independent of antigen specificity (Oncoimmunology 2013;2:e23972)
    • Decreased levels in CD4+ T cells in infants with biliary atresia, due to hypermethylation of CD11a promoter region (Biochem Biophys Res Commun 2012;417:986)
    • Increased levels in CD4+ T cells with immune thrombocytopenia (ITP) (J Clin Immunol 2011;31:632)
  • Clinical features:
CD11b
  • Alpha component of an integrin at 16p11-13.1 that mediates adhesion (OMIM: 120980 [Accessed 10 May 2021])
  • Also called integrin alpha M, Mac1 and CR3A
  • Pathophysiology:
    • Mediates monocyte / macrophage / granulocyte adhesion to substrates by opsonization with iC3b, leading to phagocytosis, neutrophil aggregation and chemotaxis
    • Ligands include fibrinogen, Factor X, ICAM1, iC3b, Saccharomyces cerevisiae, Staphylococcus epidermidis and Histoplasma capsulatum
    • Expression is associated with activation of T cells
  • Clinical features:
  • Uses by pathologists:
    • Common myeloid marker and NK (natural killer cell) antigen
    • Differentiates recovery from acute agranulocytosis (CD11b+, CD117-) from acute promyelocytic leukemia (CD11b-, CD117+) (Am J Clin Pathol 2002;118:31)
    • Differentiates Down syndrome patients with AML (usually CD13+, CD11b+) from transient myeloproliferative disorder (usually CD13-, CD11b-) (Am J Clin Pathol 2001;116:204)
    • May be useful for flow cytometry diagnosis of myelodysplastic syndrome as part of panel (Ann Clin Lab Sci 2012;42:271)
  • Positive staining - normal:
    • Granulocytes, macrophages
    • Follicular dendritic cells, myeloid cells beginning with promyelocytes, NK cells, some B / T cells

  • Negative staining: B cells, follicular dendritic cells
CDw12
CD13
CD14
  • Pattern recognition receptor that detects antigenic molecules on the surface of various microorganisms
  • Also called lipopolysaccharide (LPS) receptor, monocyte differentiation antigen
  • Mutations can prevent adequate inflammatory response to infection, leading to systemic infections
  • Pathophysiology:
    • GPI linked pattern recognition receptor that detects antigenic molecules on the surface of bacteria (lipoteichoic acid on gram positive, lipopolysaccharides on gram negative), myobacteria (glycolipids) and fungi (mannans), as part of the innate (nonadaptive) immune system (adaptive immune system refers to lymphocytes recognizing microorganism proteins via T cell receptors and antibodies) (Wikipedia: Innate Immune System [Accessed 10 May 2021]
    • Soluble form of CD14 is secreted by liver and monocytes; in low concentrations it confers LPS responsiveness to cells which are otherwise CD14 negative
    • Macrophages with a multiprotein complex of CD14, MD2 and TLR4 bind to LPS, causing macrophage activation and release of cytokines (Mol Immunol 2014;57:210)
    • Detection of lipopolysaccharide induces IL12 production (mediated by CD14), producing interferon gamma, which steers immune system away from allergy driven Th2 phenotype, associated with IgE production
    • Important for clearance of apoptotic cells (Nature 1998;392:505, PLoS One 2013;8:e70691)
    • Early promonocytes express MY4 epitope; mature monocytes express MO2 epitope; neoplastic monocytes also often express MY4 but not MO2 (Am J Clin Pathol 2005;124:930)
  • Clinical features:
  • Uses by pathologists: identify mature monocytes / macrophages
  • Positive staining - normal: macrophages / monocytes (90%), Langerhans cells, dendritic cells, B cells and granulocytes (weak, 30%)

  • CD14+ CD16+ monocytes have increased capacity to produce proinflammatory cytokines such as TNF alpha and are elevated in various inflammatory diseases, including coronary artery disease (Thromb Haemost 2004;92:419)
  • CD16a polymorphisms influence:
    1. Severity but not the incidence of IgA nephropathy in Japanese patients (Nephrol Dial Transplant 2005;20:2439)
    2. Pathogenesis of coronary artery disease (Atherosclerosis 2005;180:277)

  • Pathophysiology:
  • Clinical features:
    • Deficiency of the CD18 component (leukocyte adhesion deficiency type 1) is a rare, inherited disorder, causing severe leukocytosis and recurrent severe bacterial infections early in life of skin and mucosal surfaces, possibly fatal, due to defective white blood cell adherence, chemotaxis, phagocytosis and bacterial killing (OMIM: 116920 [Accessed 11 May 2021], J Clin Immunol 2010;30:756)
