Abstract excerpt
CRM107 (crossreacting material 107), a double point mutant of diphtheria toxin that lacks receptor-binding activity, specifically kills cerebellar Purkinje cells in vivo. After injection into guinea pig cerebrospinal fluid, CRM107 (0.9 micrograms) and CRM107-monoclonal antibody conjugates (10 micrograms) kill up to 90% of the total Purkinje cell population with no detectable toxicity to other neurons. Animals...
