In macrophages, mitochondria are central to immunometabolic responses to external cues, but the extent to which they are remodeled and participate in macrophage reprogramming remains unclear. Here, we integrate transcriptomics with whole-cell and purified mitochondrial proteomics to profile LPS/IFNγ- and IL-4/IL-13-stimulated macrophages. We reveal a striking disconnect between mitochondrial transcript and protein levels following either stimulus, and a STAT6-dependent increase in mitochondrial DNA (mtDNA) expression and intramitochondrial translation in IL-4/IL-13 macrophages. We demonstrate that pharmacological inhibition of mitochondrial translation or individual respiratory chain complexes variably impairs reprogramming, whereas ATP synthase inhibition uniquely triggers an HRI-dependent integrated stress response (ISR) through mitochondrial hyperpolarization, thereby preventing IL-4/IL-13 reprogramming. Mechanistically, we show that restoring mitochondrial membrane potential or inhibiting the ISR rescues IL-4/IL-13-mediated reprogramming. Together, we identify mtDNA expression, intramitochondrial translation, and mitochondrial membrane potential as critical, drug-sensitive determinants of the IL-4/IL-13 response.2026/06/29GSE335147GSM9806719GSM9806729GSM9806733GSM9806722GSM9806721GSM9806732GSM9806724GSM9806735GSM9806734GSM9806723GSM9806726GSM9806737GSM9806736GSM9806725GSM9806739GSM9806728GSM9806738GSM9806727GSM9806740GSM9806742GSM9806731GSM9806720GSM9806741GSM980673034475335147Mus musculus
