摘要：

Cytokine-induced neutrophil chemoattractant-1 (CINC-1) is a member of the chemokine superfamily. The effect of intracerebroventricular (i.c.v) injection of CINC-1 on the mechanical nociceptive threshold in the rat was examined using the paw-pressure test. An i.c.v. injection of CINC-1 at doses of 1 and 10 pg/rat tended to decrease the nociceptive threshold for mechanical stimuli at 15 min after the injection, and significantly lowered the threshold at 30 min. The threshold stayed at these lowered level over 180 min after the injection. Lower (100 fg/rat) and higher (30 and 100 pg/rat, and 1 and 10 ng/rat) doses of CINC-1 had no effect on the mechanical nociceptive threshold. The present results suggest that CINC-1 facilitates mechanical nociception in the central nervous system (CNS). (C) 1998 Elsevier Science B.V. All rights reserved.
