CCR5 is required for hepatic fibrogenesis and in CCR5 -/- fibrosis is lower than in wild type. WT CCR5-/- Ekiro S et al. J Clin Invest. 2009; 119: WTCCR 5 -/- WTCCR5 -/- Macrophage infiltration is lower in CCR5 -/- Role of CCR5 in fibrogenesis HSCs proliferation and migration are largely mediated by CCR5. CCR5 contributed to 70% of rhRANTES-induced signaling events and appears to be the major the receptor for RANTES in HSCs.

Our data indicate that higher HCV RNA levels are associated with the presence of IR in CHC patients IR was positively correlated with body mass index, triglyceride, HCV-RNA and ALT level and negatively correlate with adiponectine.

Conclusione La co-infezione con virus epatite C è la più grave co-morbidità nelle persone HIV positive Limmunoricostituzione è essenziale per ridurre la progressione della malattia di fegato Nel lungo tempo la tossicità epatica e metabolica di alcuni farmaci antiretrovirali, e la condizione di immonoattivazione cronica potrebbero incrementare i processi fibrogenetici La scelta di una terapia antiretrovirale ottimale nel soggetto co- infetto potrebbe essere la prima, e nei soggetti non eleggibili allinterferone, lunica possibilità per rallentare la progressione della malattia di fegato
