bacillus coagulans t4 and lactobacillus paracasei td3 ameliorate skeletal muscle oxidative stress and inflammation in high-fat diet-fed c57bl/6j mice

Background: this study aims to investigate the effects of bacillus coagulans t4 and lactobacillus paracasei td3 probiotics on skeletal muscle inflammation and oxidative stress in c57bl/6j mice fed a high-fat diet (hfd). methods: probiotics b. coagulans t4, andl. paracasei td3 were administered to male c57bl/6j mice fed withhfd. the gene expression of macrophage infiltration markers, inflammatory cytokines, and oxidative stress indicators in the muscle tissue was investigated. results: treatment with b. coagulans t4 and l. paracasei td3 reduced macrophage infiltration, accompanied by a decrease in the expression of monocyte chemoattractant protein-1 (mcp-1) and an increase in the expression of interleukin (il)-10. on the other hand, l. paracasei td3 decreased malondialdehyde (mda) while b. coagulans t4 decreased carbonyl and increased catalase activity. conclusions: treatment with probiotics b. coagulans t4 and l. paracasei td3 partially ameliorated obesity-induced skeletal muscle inflammation in hfd-fed mice.
