Lipids, GTPases, and their regulators in membrane dynamics: an intracellular ménage à trois
نویسندگان
چکیده
Essentially all aspects of eukaryotic cell physiology depend on their compartmentalization and on membrane flux between these compartments mediated by small GTPases and their regulators, as well as by specific membrane lipids (Behnia and Munro, 2005). Talks at the Minisymposium on “Membrane Traffic: Dynamic and Regulation” featured how Rab-and Arf-family GTPases, together with diverse phospholipids, most notably phosphoinositides (Balla, 2013), control key cell functions ranging from plasma membrane compartmentalization to organelle contacts, endosomal fission, cell motility, intracellular signaling, and cell cycle progression.

GABAA, NMDA and AMPA receptors: a developmentally regulated 'ménage à trois'.
The main ionotropic receptors (GABAA, NMDA and AMPA) display a sequential participation in neuronal excitation in the neonatal hippocampus. GABA, the principal inhibitory transmitter in the adult CNS, acts as an excitatory transmitter in early postnatal stage. Glutamatergic synaptic transmission is first purely NMDA-receptor based and lacks functional AMPA receptors. Therefore, initially glutam...

Regulated termination of stem cell maintenance is required to complete reproductive development in plants. Two recent studies have revealed a new relationship for some old suspects; the WUSCHEL gene, which promotes indeterminancy, is involved as well as the floral regulators LEAFY and AGAMOUS.

Membrane/ protein trafficking in the secretory/ biosynthetic and endocytic pathways is mediated by vesicles. Vesicle trafficking in eukaryotes is regulated by a class of small monomeric GTPases the Rab protein family. Rab proteins represent the largest branch of the Ras superfamily GTPases, and have been concerned in a variety of intracellular vesicle trafficking and different intracellular sig...

Glioblastoma is an aggressive primary brain cancer. Given our interest in novel immunotherapies, we have recently shown that inhibiting CTLA-4, PD-L1 and IDO results in a dramatic survival advantage in mice with brain tumors. Our preclinical study supports the rapid translation of this approach into phase I clinical trial.
