Fig. 8. Rab11^N124I inhibits endocytosis in Garland cells. (A,B) Confocal cross sections of wild-type or Rab11^N124I-expressing Garland cells after 10 minutes TR-avidin uptake. Many vesicles stain in wild-type Garland cells. However, there is no avidin uptake in Rab11^N124I expressing Garland cells. (C,D) Electron micrographs of Garland cells show labrynthine channels, deep invaginations of the plasma membrane. These are lost in Rab11^N124I-expressing Garland cells. Scale bar: 5 µm in A,B; 500 nm in C,D.
