In the October 12th edition of biobytes, Vincent Hyenne and Michel

Labouesse (University of Strasbourg and Pierre and Marie Curie University, France)

describe how the Ral GTPases regulate exosome secretion in C.

elegans and cultured mouse cells (Hyenne et

al.), and Joel Swanson (University of Michigan Medical School, Ann Arbor,

MI) explains how macropinocytosis supports growth factor signaling (Yoshida et

al.). Plus a round-up of other highlights from The Journal of

Cell Biology. The show was written and produced by Caitlin Sedwick and

Ben Short. Presented by Ben Short. See the associated papers in

JCB for details on the funding provided to support these

original research studies.
