T cells revealed deregulated mitochondrial proteins (4-hydroxy-2-oxoglutarate aldolase, aspartate aminotransferase, and prostaglandin E synthase), suggesting impaired mitochondrial function. Collectively, these findings suggest that age-associated immune alterations may disrupt immunometabolic pathways, thereby contributing to the delayed Mtb clearance. Targeting immunometabolic dysfunction therefore represents a promising strategy to enhance TB treatment efficacy and reduce disease burden in older populations.
