Glutamate is believed to be the predominant excitatory neurotransmitter in the networks responsible for itch-related behavior. Beta-lactam antibiotics were shown to exert neuroprotective effects by increasing expression of the glutamate transporter GLT-1. We observed whether repeated administration of the beta-lactam antibiotic ceftriaxone suppresses serotonin-induced itch-related behavior (similarly to its effect on pain transmission) in mice. Chronic, but not acute, ceftriaxone introductions reduced the number of serotonin-induced scratches; dihydrokainic acid, a selective GLT-1 transporter inhibitor, partly but significantly abolished this effect of ceftriaxone. Our findings suggest that GLT-1 activation by beta-lactam antibiotics looks promising for the treatment of chronic itch.
