MCs are targets of SLURP-1 in the skin. (A–D) immunohistology and (E,F) HM of Chrna7 and SLURP-1 in full-thickness skin samples obtained from control and 24 h noise-stressed mice. In photomicrographs, sMC are labeled green, Chrna7 and SLURP-1 red. Each dot in the graphs represents one mouse. (G–I) cMC stimulation with SLURP-1 yielded comparable results to stimulation with the stress mediator SP and standard MC degranulators DNP-HSA, Ionomycin, Ionomycin and PMA. P < 0.01 = *. Scale bars: (A,B) 25 μm and (C,D) 10 μm. Chrna, alpha nicotinic acetylcholine receptor; DNP-HSA, Dinitrophenyl Albumin; NGF, Nerve Growth Factor; PMA, Phorbol 12-myristate 13-acetate; SLURP, secreted Ly-6/uPAR-related protein.
