PLoS ONE 9(1), e1003109 (2013). In order to understand how Borrelia burgdorferi acquires cholesterol from its host, five experiments were performed. HPTLC on silica gel with chloroform – methanol 17:3, the lipids were extracted through the Bligh and Dyer method: (1) from the spirochete incubated 4 h in a medium containing 4 mg/L BODIPY-cholesterol (fluorescing only in hydrophobic environment), (2) from the spirochete incubated 2 h in a medium containing 10 µCi/L tritiated cholesterol, (3) from HeLa cells incubated with the spirochete itself charged with tritiated cholesterol (after removal of all spirochetes). The same analysis was applied (4) to the purified outer membrane vesicles of the spirochete previously charged with BODIPY-cholesterol. In cases (1) and (4), UV detection showed that the BODIPY-cholesterol is incorporated into the cholesterol glycolipids of B. burgdorferi, whereas without incubation it has the same hRf as cholesterol. In cases (1), (2) and (4), iodine staining made free cholesterol and cholesterol-glycolipids (galactopyranosides) visible, but no other (cholesterol-free) lipids. In case (2), the chromatogram was sprayed with EN3HANCE Spray (DuPont), exposed using BioMax MR Film (Kodak) for 4 and 14 days at −80 °C and developed using a Medical Film Processor Model SRX-101A (Konica); the radiolabelled cholesterol was shown incorporated into the cholesterol-glycolipids. In cases (2) and (3), the radiolabelled zones on the layer were scraped off and analyzed by liquid scintillation counting; cholesterol-glycolipids were found (more than free cholesterol) transferred from the spirochete to the HeLa plasmalemma.
