Effects of transcutaneous needle stimulation on the immune response in rabbits.

ABSTRACT

Studies in the field of neuroimmunomodulation have shown that endorphins such as methionine-encephalin may have an immunomodulatory role. This study was undertaken to test whether transcutaneous needle stimulation, which is known to release such peptides from the central neurones, has an effect on immune response in rabbits. Twelve healthy rabbits, in three similar subgroups, were exposed to pathogenic Escherichia coli and their immune response was studied under different experimental conditions. Our results show that needle stimulation causes a reversal of stress induced suppression of antibody production. Further studies are necessary to evaluate any therapeutic uses these observations may have in humans.
