Resident tissue macrophages maintain intraocular pressure homeostasis

2 weeks 2 days ago
Intraocular pressure is tightly regulated by the conventional outflow tissues, preventing ocular hypertension that leads to neurodegeneration of the optic nerve, or glaucoma. Although macrophages reside throughout the conventional outflow tract, their role in regulating intraocular pressure remains unknown. Using macrophage lineage-tracing approaches, we uncovered a dual macrophage ontogeny with distinct spatial organization across the mouse lifespan. Long-lived resident tissue macrophages were...
