Given the similarities between the two viruses, the feline immunodeficiency virus (FIV) is becoming an interesting animal model for human immunodeficiency virus (HIV) studies. To explore the still controversial role of the liver in the development of HIV infection, sinusoidal endothelial cells (SEC) were isolated, and primary cultures were infected with the FIV Villefranche IFFA strain. The isolated cells were characterized by their typical fenestrations, the presence of von Willebrand factor (vWf), and their ability to take up acetylated low-density lipoproteins and denatured collagen. Two weeks after infection, significant amounts of FIV p24 antigen were detected by immunofluorescence in both multinucleated giant and single cells and by enzyme-linked immunosorbent assay in the culture medium. High amounts of viral particles were observed together with different steps of budding at the plasma membrane or at the membrane of intracytoplasmic vacuoles. The released viral particles were shown to be infectious for a permissive cell line. During the first 3 weeks of infection, the only cytopathic effect of FIV was syncytia formation. No noticeable impairment of the pattern of fenestrations and the modulation of their number by a cytoskeleton-mediated process occurred. The productive infection of SEC may contribute to the progression of the infection.
