CD180
- Also called RP105
- Regulates B cell recognition of lipopolysaccharide, a membrane constituent of gram-negative bacteria
- Positive staining - normal: mantle zone and marginal zone B cells (strong), other B cells (weak/negative); peripheral blood monocytes, dendritic cells
CD181
- Also called CXCR1, IL8Ralpha; previously called CDw128A
- Chemokine receptor, powerful neutrophil chemotactic factor
- Positive staining - normal: neutrophils, basophils, T cell subset, monocytes, keratinocytes
- Positive staining - disease: T cells in allergic rhinitis (J Immunol 2004;172:268)
CD182
- Also called CXCR2; formerly called CD128b
- Interleukin 8 receptor beta subunit (IL8RB); binds multiple CXC chemokines including IL-8 (CXCL8)
- Chemokine receptor, powerful neutrophil chemotactic factor, particularly to sites of inflammation
- Interpretation: cytoplasmic staining
- Uses by pathologists: no significant uses by pathologists
- Positive staining - normal: mature granulocytes, keratinocytes, neuroendocrine cells, projection neurons (Arch Pathol Lab Med 2000;124:520)
- Positive staining - disease: carcinoid tumor (classic, atypical, metastatic), pituitary adenoma, pheochromocytoma, medullary carcinoma
- Negative staining: parathyroid cells; small cell carcinoma of lung / cervix, large cell lung neuroendocrine carcinoma, Merkel cell carcinoma, neuroblastoma, melanoma
CD183
- Also called CXCR3
- Receptor for some chemokines; binding of chemokines to CD183 induces integrin activation, cytoskeletal changes and chemotactic migration in inflammation-associated effector T cells
- CD183+ T cells detected in inflamed tissues of patients with juvenile rheumatoid arthritis, multiple sclerosis, sarcoidosis, hepatitis C
- Positive staining - normal: T cells in inflamed tissue, eosinophils, plasmacytoid dendritic cells, hematopoietic progenitors
- Negative staining: naïve T cells in peripheral blood
CD184
- Also called CXCR4, Stromal cell Derived Factor 1 (SDF1)
- Receptor for the CXC chemokine SDF-1
- Also major HIV/SIV co-receptor (with CCR5/CD195)
- Involved in B cell development, myelopoiesis, cardiac ventricular septum formation, blood vessel formation in GI tract, cerebellar granular cell development
- Positive staining - normal: all mature blood cells, blood progenitor cells, endothelial and epithelial cells, astrocytes, neurons
CD185
- Multipass membrane protein of CXC chemokine receptor family
- Also called CXCR5, BLR1 (Burkitt lymphoma receptor 1)
- Pathophysiology:
- Binds to B Lymphocyte Chemoattractant (BLC / CXCL13) (J Exp Med 1998;187:655)
- Involved in B cell migration into B cell follicles of spleen and Peyer patches (J Immunol 2009;182:2610)
- Critical for function of follicular helper T (TFH) cells
- May have role in survival and maintainance of cardiac structure upon pressure overload by regulating proteoglycans essential for correct collagen assembly (PLoS One 2011;6:e18668)
- May be important for ectopic mucosa associated lymphoid tissue neogenesis in chronic Helicobacter pylori induced inflammation (J Mol Med (Berl) 2010;88:1169)
- During HIV1 infection, altered expression of CXCR5 / CXCL13 may cause B cell dysfunction (Blood 2008;112:4401)
- Upregulated in rheumatoid arthritis synovial tissue and expressed in various cell types (Arthritis Res Ther 2005;7:R217)
- Interpretation: cytoplasmic staining
- Uses by pathologists: no significant uses by pathologists
- Positive staining - normal: mature B cells
- Positive staining - disease: Burkitt's lymphoma, mantle cell lymphoma; AIDS-related non-Hodgkin lymphoma (Blood 2009;113:4604, AIDS Res Treat 2010;2010:164586)
