Immunotoxins have been used to study the targeting of biologically active substances at neurons in vivo and to make experimental neural lesions. OX7-saporin, directed against Thy 1, destroys any neuron. 192 IgG-saporin, directed against the 'low affinity' neurotrophin receptor (p 75NTR), selectively destroys neurons expressing this receptor (sympathetic, sensory, cholinergic basal forebrain, cerebellar Purkinje). Anti-D beta H-saporin, directed against dopamine beta-hydroxylase, the enzyme that converts dopamine to norepinephrine, selectively destroys noradrenergic neurons (sympathetic, CNS). These agents show that several types of neural antigens may prove useful in treating pain, and anti-D beta H-saporin may be active against pheochromocytoma or neuroblastoma.
