Article Title: Efficacy of subantimicrobial-dose doxycycline against nitrosative stress in chronic periodontitis

doi: 10.1038/aps.2012.129

Figure Lengend Snippet: Photomicrographs of representative iNOS-positive and 3-nitrotyrosine-positive stains in gingival tissue from patients with chronic periodontitis (immunohistochemical staining): (A) countless iNOS+ PMNs and monocytes (scale bar, 50 μm); (B) decreased iNOS+ cells in the SRP+placebo group (scale bar, 50 μm); (C) sparse iNOS+ cells in SRP+SDD group (scale bar, 50 μm); (D) countless 3NT+ PMNs and monocytes (scale bar, 100 μm); (E) decreased 3NT+ cells in the SRP+placebo group (scale bar, 50 μm); (F) sparse 3NT+ cells in the SRP+SDD group (scale bar, 50 μm). This figure is representative of 3 measurements (×400). iNOS+=induced nitric oxide synthase positive cells; 3NT+=3-nitrotyrosine positive cells; SRP=scaling and root planing; SDD=subantimicrobial dose of doxycycline.

Article Snippet: The following primary monoclonal antibodies were used: anti iNOS (R&D Systems, RD-MAB9502, MN, USA), anti 3-nitrotyrosine (3NT) (Novus Europe, KA0445, ABNOVA, Cambridge, UK).

Article Title: LTr1 alleviates DSS-induced ulcerative colitis by modulating macrophages to inhibit M1 polarization and associated inflammatory responses

doi: 10.3389/fimmu.2025.1651922

Figure Lengend Snippet: LTr1 reduces DSS-induced macrophage infiltration and M1 Polarization. (A) The proportions of macrophages in the splenocytes and LNLs were determined by flow cytometry analysis. (B) Protein expression levels of iNOS and CD80 in macrophages of LNLs, along with the percentage of iNOS + or CD80 + macrophages as determined by flow cytometry. (C) mRNA expression levels of iNOS , CD80 , Arg1 , CD206 in colon tissue determined by quantitative RT-PCR. All experiments were performed with n = 5 mice per group and presented as means ± SD. Statistical analysis was performed using one-way ANOVA followed by LSD multiple comparisons test. * p < 0.05, ** p < 0.01, *** p < 0.001.

Article Snippet: The following antibodies were used for flow cytometry: CD3-Brilliant Violet 510 (eBiosciences, Cat# 464882), CD11b-Brilliant Violet 421 (Biolegend, Cat# 101235), CD19-Brilliant Violet 650 (BD Biosciences, Cat# 563235), CD45-FITC (Biolegend, Cat# 103108), F4/80-PE (BD Biosciences, Cat# 565410). iNOS-APC (Miltenyibiotec, Cat# 130-116-423), CD80-Brilliant Violet 711 (Biolegend, Cat# 104743), CD206-PE/Cyanine7 (Biolegend, Cat# 141720).

doi: 10.3389/fimmu.2025.1651922

Figure Lengend Snippet: LTr1 directly acted on macrophages. (A) Cytotoxicity of LTr1 to RAW264.7 cell line was determined by CCK8 cell viability assay. (B) Protein expression levels of iNOS, CD80, and CD206 in RAW264.7 cell line was determined by flow cytometry. (C) ELISA analysis of IL-1β and IL-6 in cell culture medium. (D) mRNA expression levels of iNOS , IL-1β , and IL-6 in colon tissue determined by quantitative RT-PCR. Data were collected from at least three independent experiments and presented as means ± SD. All data statistical differences were evaluated using Permutation test and Bonferroni correction. * p < 0.05, ** p < 0.01, *** p < 0.001.
