Article Snippet: F-actin and the nuclei of PDLSCs were stained with phalloidin (Abcam, ab176757) and DAPI, respectively. .. To visualise the subcellular localisation of P. micra during infection, P. micra and PDLSCs were stained with CFSE, EEA1 (Proteintech, 68065-1-Ig), Rab7 (Zenbio, R25524) and LAMP1 (Proteintech, 21997-1-AP) and cholera toxin B (Invitrogen, C34778). .. The immunofluorescence signals were observed using a confocal laser scanning microscope (Leica, Wetzlar, Germany).

Article Title: β - sitosterol promotes the SUMOylation of DRP1 in alveolar macrophages and alleviates sepsis-associated acute lung injury.
Article Snippet: Acute lung injury (ALI) represents the most frequent complication of sepsis; however, effective drug-based interventions are still unavailable. β-sitosterol (BS) has demonstrated anti-inflammatory effects and protective properties on alveolar epithelial barriers.. This study investigated the mechanism by which BS targets alveolar macrophages to attenuate sepsis-associated acute lung injury (SALI) via in vivo and in vitro experiments.. Sepsis was induced in mice through cecal ligation and puncture (CLP), and BS was administered orally.

Article Snippet: After treatment, the cells were washed twice with PBS and fixed in 4% paraformaldehyde for 20 min. For intracellular protein staining, fixed cells were permeabilized with 0.1% Triton X-100 at room temperature for 10 min. Next, the cells were blocked with 2% BSA and incubated with rat CoraLite Plus 488 anti-mouse LAMP1 antibody (1:200) and rabbit anti-mouse pSAP (1:200) antibody overnight at 4 °C.
