Gut Bacteria and Aldosterone Influence Heart Stress Signals to Trigger Cell Cleanup and Energy Changes in a Sepsis-Like Heart Injury Model

Natriuretic peptide B (NPPB) is implicated in gut-heart communication during sepsis-induced myocardial injury.

• Myocardial injury contributes significantly to mortality in sepsis.
• The role of gut microbiota and aldosterone in myocardial health is being explored.
• NPPB is involved in regulating cardiac stress responses.
• The exact mechanisms of NPPB in mitochondrial function and metabolism remain unclear.
• The effects of gut microbiota and aldosterone on mitophagy and metabolic changes in the heart are under investigation.
