Article Title: Glutamine alleviates Staphylococcus aureus -induced mastitis by modulating macrophage polarisation
doi: 10.1371/journal.ppat.1014053
Figure Lengend Snippet: Mice were orally administered αKG prior to establishment of a S. aureus -induced mastitis model. Mammary gland tissues were subsequently collected for analysis (n = 7 per group). A: Mitochondrial superoxide levels in frozen mammary gland tissue sections were assessed using MitoSOX Red staining, with green fluorescence indicating ROS. B: ATP levels in mammary gland tissues from Control, S. au, and αKG + S. au . C-D: OCR of mammary gland tissue cells in the three groups. E: Expression of LC3, ATG5, and p62 in protein lysates of mammary tissues from the three groups. G-H: RAW264.7 cells cultured with αKG were treated with oligomycin A and stimulated with S. aureus . Inflammatory cytokine levels and NF-κB signaling pathway activity of Control, S. au, αKG + S. au, αKG + S. au +oligomycin A were measured. I-P: qPCR analysis of M2 and M1 marker gene mRNA expression in four experimental groups of RAW264.7 cells. The data are presented as mean ± SD. One-way analysis of variance was performed for statistical analysis. * P < 0.05, ** P < 0.01 and *** P < 0.001 indicate significance from each group. ns, no significance.
