doi: 10.3390/biomedicines12112624
Figure Lengend Snippet: p75NTR modulation reduces IL-6 and IL-8 expression in RTT fibroblasts. Representative immunofluorescence and respective quantitative analysis of ( A ) IL-6 immunoreactivity in control fibroblasts (HC-1), Rett syndrome fibroblasts (RTT-1), and RTT fibroblasts treated with LM11A-31(RTT-1+LM) at the dose of 0.1 μM for 24 h. Cells were fixed in 4% PFA and stained with antibodies against IL-6 (red). DAPI was used to counterstain nuclei. n = 6 biological replicates. Images were acquired using the Leica TCS SP8 confocal microscope and Leica Application Suite X (LAS X) software at 40× magnification. Scale bar: 50 µm. ( B ) ELISA on IL-6 in culture medium from HC-1, RTT-1, and RTT-1+LM groups treated as abovementioned. n = 4 biological replicates. ( C ) IL-8 immunoreactivity (red) and respective quantitative analysis performed on HC-1, RTT-1, and RTT-1+LM fibroblasts treated as in ( A ). DAPI was used for nuclear staining. n = 6 biological replicates. Scale bar: 50 µm. ( D ) ELISA on secreted IL-8 in conditioned medium from HC-1, RTT-1, and RTT-1+LM cells treated as abovementioned. n = 4 biological replicates. Data are expressed as mean ± SD. Statistical analysis was performed using one-way ANOVA, followed by Tukey’s post hoc test. Statistical significance is indicated as follows: * p < 0.05; ** p < 0.01; *** p < 0.001. “a” indicates statistical significance vs. HC-1; “b” indicates statistical significance vs. RTT-1.
Article Snippet: The anti-NGF and anti-p75NTR antibodies were validated using NGF (BLP-N240, Alomone labs, Jerusalem, Israel) and p75NTR (BLP-NT011 Alomone labs, Jerusalem, Israel) blocking peptides.
