Neuronal differentiation is characterized by neuritogenesis and neurite outgrowth, processes that are dependent on membrane biosynthesis. Thus, the production of phosphatidylcholine (PtdCho), the major membrane phospholipid, should be stimulated during neuronal differentiation. We demonstrate that during retinoic acid (RA)-induced differentiation of(More)
Neuronal differentiation is characterized by neuritogenesis and neurite outgrowth, processes, which are critically dependent on membrane biosynthesis, and therefore, on the expression and regulation of enzymes involved in phospholipid biosynthesis. During the last decade a great effort was made to clarify where membrane lipids are synthesized, how the newly(More)
During the late stages of the HIV-1 replication cycle, the viral polyprotein Pr55(Gag) is recruited to the plasma membrane (PM), where it binds phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) and directs HIV-1 assembly. We show that Rab27a controls the trafficking of late endosomes carrying phosphatidylinositol 4-kinase type 2 α (PI4KIIα) toward the PM of(More)
Neuronal differentiation plays a key role during embryogenesis. However, based on the capacity of neuronal stem cells to either generate or regenerate neurons and because differentiation stops aberrant neuroblasts proliferation, neuronal differentiation is crucial during neuropathological conditions. Although phosphatidylcholine (PtdCho) has been proposed(More)
