doi: 10.1126/sciadv.aea7017
Figure Lengend Snippet: ( A ) Volcano plots illustrated the expression of adrenergic receptors on fibroblasts in human skin, including ADRA1A, ADRA1B, ADRA1D, ADRA2A, ADRA2B, ADRA2C, ADRB1, ADRB2, and ADRB3. ( B ) Bubble map illustrated the up-regulation of ADRA2A expression on fibroblasts in the lesional skin of patients with vitiligo and the normal skin of healthy controls. ( C ) Representative immunofluorescence images of fibroblasts, ADRA2A, CXCL9, CXCL10, and CD8 + T cells from the normal skin of the healthy control and the lesional skin of the patient with vitiligo ( n =3 per group). Nuclei were counterstained with DAPI (blue). Scale bars, 50 μm. ( D ) Immunofluorescence analysis of ADRA2A (red) expression in BJ cells after treatment with 5 μM NE for 48 hours. Cell nuclei were stained with DAPI (blue). Scale bar, 50 μm. ( E ) Secretion levels of CXCL9, CXCL10, IL-6, and IL-15 in BJ cells were detected by ELISA with treatment with aposcopolamine (Apos) or NE ( n =3 per group). ( F ) Secretion levels of CXCL9, CXCL10, IL-6, and IL-15 in BJ cells with ADRA2A siRNA or control siRNA were detected by ELISA ( n =3 per group). Error bars represent mean ± SD from three independent experiments. * P < 0.05, ** P < 0.01, and *** P < 0.001; ns, not significant.
