Hypothesis

OxLDL would lead to glycolytic reprogramming and proinflammatory responses in monocytes, and that Mdivi-1 would reduce or prevent these responses.

Conclusion

Mdivi-1 effectively reduces the metabolic shift towards glycolysis induced by OxLDL, decreases foam cell formation, and lowers gene expression of inflammatory cytokines.

Supporting Evidence

  • Mdivi-1 reduced OxLDL-induced glycolytic reprogramming.
  • Mdivi-1 decreased expression of inflammatory cytokines IL1B and CXCL8.
  • Mdivi-1 limited foam cell formation in monocytes.
  • OxLDL treatment increased glycolytic activity in monocytes.
  • Both Mdivi-1 and S1QEL modulated key monocyte responses to OxLDL.

Takeaway

This study shows that a compound called Mdivi-1 can help stop bad changes in immune cells caused by a harmful substance, which could help prevent heart problems.

Methodology

Healthy monocytes were treated with OxLDL, with or without Mdivi-1 or S1QEL, and assessed for metabolic shifts, inflammatory cytokine expression, foam cell formation, and ROS production.

Limitations

In vitro results may not completely represent outcomes in a more complex in vivo setting.

Participant Demographics

Healthy, non-obese young adults aged 18 to 40.
