A lack of viral replication after HIV-1Ba-L (R5) but not HIV-1IIIB (X4) infection was found using in-vitro activated peripheral blood-derived mononuclear cells from patients with Fabry disease, who have a defect in the catabolism of globotriaosylceramide. CCR5, but not CD4 or CXCR4 expression levels, were lower and the surface expression of globotriaosylceramide was negligible on activated patients cells. Our findings suggest a novel resistance mechanism to productive infection with R5 HIV-1 that potentially involves abnormal globotriaosylceramide catabolism.
