Attenuation of irradiation (IR)-induced neutrophil infiltration by botulinum toxin (Botox) injection. After focal irradiation (15 Gy), submandibular glands (SMGs) were removed after 3 days. SMG sections from glands preinjected with botox or saline were stained with cytokeratin 7 (red), myeloperoxidase (green), and DAPI (blue) and imaged by confocal microscopy. Percentage of myeloperoxidase positive cells was averaged over 3 experiments with 4 fields per slide analyzed (**P<.01). A color version of this figure is available at www.redjournal.org.
