In the July 20th edition of biobytes, Karen Hedin (Mayo Clinic,

Rochester, MN) describes how cells regulate the endocytic trafficking of the CXCR4

chemokine receptor (Bamidele et

al.), and Tâm Mignot (Aix Marseille University, Centre National

de la Recherche Scientifique, Marseille, France) and Lotte

Søgaard-Andersen explain how a small GTPase regulates bacterial focal

adhesions (Treuner-Lange

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.
