Article Title: The metabolic reprogramming of T cells controls airway remodeling in severe asthma

doi: 10.64898/2026.03.19.712985

Figure Lengend Snippet: To model EA or MGA respectively, Balb/c or Il4ra -/- mice were given five intranasal (i.n.) challenges with 100ug house dust mite (HDM) extract every week (followed by two days resting) for three consecutive weeks. A final i.n. HDM challenge was given 24 hours prior to harvest. ( A ) Lung sections were stained and representative Masson trichrome (collagen), α-smooth muscle actin (αSMA), and hematoxylin and eosin (H&E) sections and accompanying quantifications are shown. ( B ) Airway resistance to increasing doses of methacholine exposure (6-8 mice per group). (C) Expression of mRNA for IL13 and IL17, assessed by quantitative PCR analyses of lung samples. mRNA expression was calculated relative to GAPDH for 5 mice per group. ( D ) Number of neutrophils or eosinophils in the left lung lobe of EA or MGA induced mice, as assessed by flow cytometry. ( E ) MGA-induced animals were treated with 50ug dexamethasone intratracheally one hour prior to each allergen challenge, beginning on day 7. Lung sections were stained and representative Masson trichrome and αSMA sections and accompanying quantifications are shown. ( F ) Number of neutrophils or eosinophils in the left lung lobe of MGA induced mice treated with or without dexamethasone, as assessed by flow cytometry. ( G ) MGA-induced animals were treated with 100ug anti-IL17A or matching isotype control i.p. beginning on day 7 and continuing every other day until harvest. Lung sections were stained, and representative H&E sections and accompanying quantifications are shown. Trichrome data show area of interest values covering full lung section of 6 individual mice per condition. αSMA data show mean values of all bronchi scored from 6 mice per condition. Data are representative of 3 independent experiments. *P < 0.05, **P < 0.005, ***P < 0.0005, ****P < 0.00005; HPF, high-power field; ns, nonsignificant.

Article Snippet: To block IL-17 signaling, 100ug anti-IL17A (17F3; BioXCell) or matching isotype control (MOPC-21; BioXCell) were given intraperitoneally (i.p.) to HDM induced Ilr4a -/- mice beginning on day 7 and continuing every other day for a total of 7 injections.

Article Title: Acetylated Diacylglycerol 1-palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol in Autoimmune Arthritis and Interstitial Lung Disease in SKG Mice

doi: 10.3390/biomedicines9091095

Figure Lengend Snippet: Histologic examination of the lung tissue from SKG mice at 20 weeks after a curdlan injection with/without PLAG treatment. ( A ) Hematoxylin and eosin (upper panels) and Masson’s trichrome (lower panels) staining of the lung tissues. Severe lung inflammations were observed in the curdlan-induced SKG mice and these features were attenuated in the PLAG-treated curdlan-induced SKG mice. ( B ) Opal multiplexed immunofluorescent images and semi-quantitation of the total, GM-CSF + and IL-17A + neutrophil accumulation in the lung tissues. The GM-CSF + neutrophil accumulation was significantly decreased in the PLAG-treated curdlan-induced SKG mice compared with those without PLAG treatment whereas the IL-17A + neutrophil accumulation was not attenuated. The values represent the mean of three independent experiments ± SEM. * p < 0.05. PLAG: acetylated diacylglycerol 1-palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol.

Article Snippet: The slides were again placed in a citrate buffer (pH 6.0), heated in a microwave and incubated with primary rabbit antibodies for IL-17A (Novus Biologicals, Centennial, CO, USA, NBP1-76337, 1:500) for 1 h in a humidified chamber at RT followed by a detection using polymer HRP Ms + Rb.

Article Snippet: Immunoprecipitation was carried out using 100 g mouse anti-human IL-17A antibody (41802, R&D Systems) and 60 g goat anti-human IL-17A antibody (AF-317-NA, R&D Systems) coupled to 1 mL HiTrap NHS-activated HP columns and AKTAprime Plus low-pressure affinity chromatography system (both from GE Healthcare) using the manufacturer’s protocol.
