There is increasing recognition of the potential morbidity and mortality associated with HIV-1 and hepatitis C (HCV) co-infection. HIV appears to adversely affect HCV disease while the reciprocal effect of HCV on HIV remains controversial. We therefore studied the effect of co-infection on dendritic cell function versus HIV infection alone, as previous work has shown that HCV impairs dendritic cell (DC) function. HIV-1 positive individuals with HCV were matched for CD4 count, HIV-1 RNA viral load and therapy, to HIV-1 positive patients without HCV. Monocyte-derived DC were generated and mixed leukocyte reactions were performed. We assessed allostimulatory capacity with and without administration of exogenous Thl cytokines, using thymidine uptake and cell division analyses with the vital dye CFSE. We found that monocyte-derived DC from co-infected individuals showed no significant differences in allostimulatory capacity to ex vivo generated DC from HIV-1 infected individuals without HCV. Unlike the situat
