Sympathetic innervation of the eye by the SCG is required for suppression of the DTH response against eye-derived antigens. Seven days after anesthesia alone (intact), SHAM, or SCGX mice were injected into the AC with OVA (B) or saline (C). Ten days later all mice were injected with subcutaneous OVA in the ear as described in Materials and Methods. Ear swelling was measured 24 hours later, also as described in Materials and Methods. *P < 0.05; **P < 0.01. A representative experiment of three is shown.
