Definition / general
Clinical features
  • Aberrant CCR7 expression in various malignancies has been linked to pro-survival, -invasive, and -metastatic pathways (J Biol Chem 2012;287:3581)
  • CCR7-CCL21 pathway may have role in rheumatoid arthritis angiogenesis (Arthritis Rheum 2012;64:2471)
  • Macrophages participate in lymphangiogenesis in idiopathic diffuse alveolar damage through CCL19-CCR7 signal (Hum Pathol 2009;40:1553)
  • 85 year old man with primary cutaneous aggressive epidermotropic CD8+ T cell lymphoma which transformed from indolent to aggressive phase in association with CCR7+ conversion (Dermatol Online J 2012;18:5)
Uses by pathologists
  • Tumor infiltration by CCR7+ T cells may be favorable prognostic marker in advanced colorectal carcinoma (Clin Cancer Res 2012;18:850)
