Dynamin-independent synaptic vesicle retrieval?

Helmut Kr|[auml]|mer & Ege T Kavalali

A new study proposes that synaptic vesicle endocytosis at a large synaptic terminal is partly independent of dynamin and GTP hydrolysis, suggesting a new mechanism leading to vesicle fission and maintenance of neurotransmission. Among the most astonishing mutants in flies are the temperature-sensitive alleles of shibire. These mutants are paralyzed when their temperature is raised to 30 |[deg]|C, yet they resume activity rapidly after their return to 25 |[deg]|C.
