Male and female WT and CD118-/- mice (6-10 weeks of age) were anesthetized by i.p. injection with xylazine (6.6 mg/kg) and ketamine (100 mg/kg) followed by scarification of the cornea using a 25 5/8-gauge needle. The tear film was then blotted, and the cornea was topically inoculated with 1,000 PFU of HSV-1 in 3 μl of RPMI-1640 medium. HSV-1 viral titers were determined in the designated tissue at times post infection (pi) by plaque assay as previously described (32 (link)).
