A CD4-lineage erythro-myeloid progenitor within the adult bone marrow defines an alternative pathway for macrophage generation

These findings reveal an alternative pathway of adult myelopoiesis that sustains macrophage diversity beyond the classical monocyte lineage. Transcriptomic comparisons position EMPROR cells closest to embryonic erythro-myeloid progenitors, indicating the persistence of an embryonic-like program in adult bone marrow.

Compartment-specific PPARδ activity controls the outcome of cancer-immune cell competition and immunotherapy efficacy

These findings identify compartment-specific PPARδ activity as a targetable driver of immune cell fitness that can be harnessed to improve outcomes in immunotherapy-resistant tumors. Therapeutically, PPARδ-activated CD8 + T cells sensitize immunotherapy-resistant microsatellite stable metastatic colorectal cancer to checkpoint blockade in mice, and pharmacological or genetic PPARδ activation enhances human chimeric antigen receptor T cell function.
