Neural modulation of ocular immunity: Exploring a sympathetic‐macrophage neuroimmune link in the human ciliary body

open access: yesJournal of Anatomy, EarlyView.
Using microscopy and 3D confocal imaging on seven cadaveric eyes, we identified sympathetic nerves closely associated with β₂‐adrenergic receptor‐expressing macrophages in the human ciliary body (CB). These findings suggest a sympathetic‐macrophage neuroimmune link in the CB, potentially influencing ocular inflammation and degeneration, warranting ...
