Implication

Review demonstrates dual defensive and destructive actions of macrophages during toxicant exposure, highlighting their therapeutic potential in mitigating tissue damage and fibrosis.

Key Points

To review the mechanisms through which resident and infiltrating macrophages mediate both protective wound healing and toxicant-induced tissue destruction.
Synthesized accumulated evidence investigating direct toxicant cytotoxicity alongside indirect tissue damage driven by macrophage activity.
Evaluated the mediator profiles and environmental cues that govern phenotypic transitions among distinct macrophage subpopulations.
Exposure to diverse toxicants induces macrophage hyperresponsiveness, prompting dysregulated mediator secretion that intensifies acute tissue injury and drives chronic disease progression, including fibrosis and tumorigenesis.
Phenotypic diversity in macrophages is directed by microenvironmental signaling, allowing distinct subsets to differentially orchestrate cytotoxic, inflammatory, angiogenic, and repair processes.
