Deleting specific nerve cells from the nervous system can block chronic
pain in dogs, report scientists from the National Institute of Dental and
Craniofacial Research, in Bethesda, Md. The cells, C-fiber neurons, can also
be deleted from human neurons cultured together in the laboratory, suggesting
that the strategy may also work in humans (J Clin Invest. 2004;113:1344-1352).
The research included 8 dogs severely affected by osteoarthritis, cancer-related
pain, or both. All of the treated animals became more active and walked with
only a slight limp or none at all. None suffered adverse effects.
