Figure Legend Snippet: Increased S100A8/9 expression in the skin and serum of patients with BP and AD. ( a ) Immunohistochemical analysis with anti-S100A8/9 antibody showing the expression of S100A8/9 in keratinocytes and infiltrating inflammatory cells of lesional skin of patients with BP and AD. S100A8/9 expression was not observed in the healthy skin. Scale bar: 100 μm. (b) Quantification of the expression level of S100A8/9. (control, n = 2; BP, n = 5; AD n = 2). Inter-patient heterogeneity of the expression level of S100A8/9 was observed in the BP skin samples, and representative images of both low and high S100A8/9 expression were shown in A. (c) ELISA analysis showing increased S100A8/9 concentrations in the serum of patients with BP. (control, n = 8; BP, n = 16; P = .0087, Mann-Whitney test). Data are reported as mean ± SD. AD, atopic dermatitis; BP, bullous pemphigoid.
Techniques Used: Expressing, Immunohistochemical staining, Control, Enzyme-linked Immunosorbent Assay, MANN-WHITNEY
Figure Legend Snippet: S100A8/9 directly activates small-diameter, nociceptive DRG sensory neurons. ( a ) Representative fluorescent images of cultured DRG sensory neurons isolated from Pirt GCaMP3/+ mice before and after S100A8/9 (100 ng/ml) application. Arrows point to sensory neurons showing increased GCaMP3 fluorescence levels after S100A8/9 application. (b) Histogram showing size distribution of S100A8/9-responsive neurons. (c–e) Representative traces of DRG neurons evoked by indicated chemicals, including S100A8/9 (100 ng/ml), S100A8 (100 ng/ml), S100A9 (100 ng/ml), capsaicin (1 μM), and KCl (75 mM) in a calcium imaging assay. All S100A8/9-sensitive neurons responded to capsaicin and KCl. The majority of S100A8- and S100A9-responsive neurons also responded to S100A8/9. The three different colors (Red, Green, and Blue) represent individual cells in C-E. (f) TAK-242 inhibited S100A8/9-induced calcium responses in sensory neurons. (n = 3 for both groups P = .018, Welch’s t -test). Data are reported as mean ± SD. AD, atopic dermatitis; BP, bullous pemphigoid; DRG, dorsal root ganglia.
Techniques Used: Cell Culture, Isolation, Fluorescence, Imaging
Figure Legend Snippet: S100A8/9 potentiate histamine-induced itch. ( a ) Subcutaneous injection of S100A8/9 (20 μg/ml) into the nape of the neck of wild-type mice does not induce scratching behavior. (n = 7 for both groups, P = .97, Welch’s t test). (b) Co-injection of S100A8/9 increased histamine (20 mM)-induced scratching behavior. (n = 11 for both groups, P = .038, Welch’s t test). Data are reported as mean ± SD.
