Article Title: Aqueous Artemisia argyi extract mitigates acute lung injury in association with coordinated alterations in gut microbiota, metabolic homeostasis, and pulmonary inflammatory gene expression

doi: 10.3389/fimmu.2026.1770675

Figure Lengend Snippet: AEAA pretreatment is associated with reduced pathological features of LPS-induced acute lung injury in mice. (A) Experimental design of the LPS-induced acute lung injury (ALI) model. (B) Histopathological evaluation of lung tissues. Representative H&E-stained sections from different treatment groups at 20× and 40× magnification show alveolar wall thickening, inflammatory cell infiltration, hemorrhage, and edema in LPS-treated mice. AEAA treatment dose-dependently ameliorated these pathological alterations (red boxed areas). (C) Wet-to-dry (W/D) lung weight ratio. (D) Lung injury score. (E–G) Pro-inflammatory cytokines in serum and BALF.IL-1β (E) , IL-6 (F) , and IL-10 (G) levels in serum and BALF. (H) TNF-α levels in serum and BALF. (I) Myeloperoxidase (MPO) activity. Data are presented as mean ± SEM. n = 5 per group. Statistical analysis was performed using one-way ANOVA followed by post hoc tests. * P < 0.05 , ** P < 0.01 , *** P < 0.001 , **** P < 0.0001 .

Article Title: A new recombinant MS-superoxide dismutase alleviates 5-fluorouracil-induced intestinal mucositis in mice

doi: 10.1038/s41401-019-0295-8

Figure Lengend Snippet: Effects of MS-SOD on tight junctions and cytokines in the small intestine after 5-FU treatment. qPCR analysis was performed to measure the transcription levels of occludin ( a ), IL-6, IL-17α, IL-22 ( c ), CXCL1 and CXCL2 ( d ). Western blotting was used to measure the translation level of occludin ( a ). An ELISA was used to measure the IL-6 concentration in serum ( c ). Both occludin mRNA and protein levels in the small intestine were decreased in mice after 5 days of 5-FU injection but were increased in the MS-SOD group. The mRNA expression levels of the main pro-inflammatory cytokines, IL-6, IL-17α and IL-22 as well as the chemokines CXCL1 ans CXCL2, were upregulated in the 5-FU group, but these cytokines were downregulated in MS-SOD-treated mice. The serum IL-6 concentration was in accordance with the mRNA level. ELISA method was used for MPO content measure. MPO content in intestinal tissue homogenates was significantly increased in the 5-FU group, but did not decrease in MS-SOD group ( b ). The data are shown as the means ± SEM ( n = 6). * P < 0.05, ** P < 0.01, *** P < 0.001. In a , the repeated blots in each group indicate three individuals

Article Snippet: Moreover, a mouse myeloperoxidase (MPO) ELISA kit (Cusabio, Wuhan, China) was used to detect MPO content.

Article Title: Rescuable effect of R-salbutamol in LPS-induced immune dysfunction of sepsis

doi: 10.1101/2021.05.17.444573

Figure Lengend Snippet: Effects of R-sal, S-sal, Rac-sal or Dex pretreatment on myeloperoxidase (MPO) level in the lung tissues of LPS-induced septic mice. The lung tissue for the MPO determination was collected 6h after LPS challenge. Data are presented as mean ± SD (n=3). ****p<0.0001 vs the control group; # p<0.05 vs the LPS group.

Article Snippet: The supernatant was then collected and measured using a mouse myeloperoxidase (MPO) ELISA kit following the manufacturer’s instructions (MultiSciences Biotech Co., Ltd, Zhejiang, China).
