Figure 1.

Localisation of scavenger receptor class B type I (SR-BI) in the enterocyte in the fasting state. In the brush border, immunogold labelling was seen over the microvilli as well as at the base of the microvilli (MM) and in invaginations between adjacent microvilli (A). In the cytoplasm, labelling was seen in an apical tubulovesicular compartment (TVC) (B), and in small lipid droplets (LD) (C, D). Multivesicular bodies/lysosomes (MB) and mitochondria (MI) were not labelled (D). Bars 0.5 μm.
