Neutralization of NGF-induced chemotaxis by C botulinum C2 toxin.
PMCs were allowed to migrate toward 50 ng/mL NGF for 3 hours following pretreatment with or without 300 ng/mL C botulinumC2 toxin for 2 hours. Data were obtained from 4-5 separate experiments. *P < .001, when compared with NGF alone.
