Article Title: Chemokine CCL19 and Its Receptors CCR7 and CCRL1 in Chronic Rhinosinusitis
doi: 10.2147/JIR.S453567
Figure Lengend Snippet: Sinonasal epithelial cell expression of CCL19 and its receptors CCR7 and CCRL1 is elevated in CRSwNP (n=7) compared to in CRSsNP (n=6) and controls (n=6). ( A ) Representative immunohistochemical images demonstrate the increased co-expression of CCL19 and typical receptor CCR7 (top), as well as of CCL19 and its atypical receptor CCRL1, in the sinonasal epithelium in patients with CRSwNP compared to in CRSsNP and controls. CCL19 appears gray, whereas its receptors appear dark brown. ( B ) CCL19 and CCR7 co-expression in the sinonasal epithelium, represented as the % total area via Image J analysis, is significantly elevated in CRSwNP compared to CRSsNP ( p =0.04) and controls ( p =0.06). ( C ) Although not significant, CCL19 and CCRL1 co-expression is elevated in CRSwNP compared to in CRSsNP and controls, represented as the % total area via Image J analysis. Data is represented by individual values with the mean ± SD with respect to cohort.
Article Snippet: The tissues were then incubated with polyclonal rabbit anti-human CCR7 (1:200, 4°C, overnight) (Bioss Antibodies, bs-1305R; Woburn, MA, USA), followed by incubation with ImmPRESS TM HRP anti-rabbit IgG (20 min) and detection with ImmPACT DAB Peroxidase kits from Vector Laboratories (Burlingame, CA, USA).
