Vimentin Mediates Uptake of C3 Exoenzyme
Figure 1
Binding of C3 to HT22 cells after pronase treatment.
A) Pronase pre-incubated HT22 cells were exposed to 100 or 500 nM of C3 for 1 h at 4°C. Subsequently, β-actin and bound C3 were detected by Western blot. NC = negative control without C3, PC = positive control lysate with 10 ng C3. One representative experiment is shown (n = 3 independent experiments). B) Pronase-treated HT22 cells were exposed to 500 nM of C3-E174Q-FITC for 1 h at 4°C and bound C3- E174Q-FITC was analyzed by FACS.
