Figure 3. Immunofluorescent staining of LC3B in autophagic vesicles. Cells were exposed for 72 h to 20 nM rapamycin (rapa) and combinations with 100 µM TdR and/or 10 µM TPI. The figure is representative for three independent experiments. Rapa: Rapamycin; TdR: thymidine; TPI: thymidine phosphorylase inhibitor.
