Abstract

Aim. Chemokines play cl ey role in dir eting [eucocyte trafficking by inrerneting with seven-trnnsmembr:mt: domain G-proteincoupled receptor Ch 'mokines and their ree ptor are prime targets for thc dcvelopmt:Ol of new therapeurie strategies aimed at eunrralling che· mia (60 min) follm ed by reperfusion (6,12,24 h) induced PMI infiltr:: ltion, a' well as hepatoeellulaI necrosis in the vehicle treatecl animai .. Treatment of rat with Repertaxin Cfour c10ses of 1-mg/kg, cadI one) reclu<.:ed PiVU\, infiltIation by almost 50'% and hepatic irr versibk clamage by 70% after re-flow, as compared to vehicle lreatd animals. Conclusion. 'l'he efficacy in the experimental mode! of li er necrosis inducecl by ischemja/reperfusion along with t~lvorahle phanna 'okinetic and toxieological profile suggc -t Repertaxin as a candidate for dinical cxploitation in prevention the deleterious con.sequences of the reperfllsion damage
