The vesicle cluster as a major organizer of synaptic composition in the short-term and long-term

Authors Reshetniak S, Rizzoli SO Journal Current Opinion in Cell Biology Citation Curr Opin Cell Biol. 2021 Mar 8;71:63-68. Abstract For decades, the synaptic vesicle cluster has been thought of as a storage space for synaptic vesicles, whose obvious function is to provide vesicles for the depolarization-induced release of neurotransmitters;

The mRNA-Binding Protein RBM3 Regulates Activity Patterns and Local Synaptic Translation in Cultured Hippocampal Neurons

Authors Sertel SM, von Elling-Tammen MS, Rizzoli SO Journal Journal of Neuroscience Citation J Neurosci. 2021 Feb 10;41(6):1157-1173. Abstract The activity and the metabolism of the brain change rhythmically during the day/night cycle. Such rhythmicity is also observed in cultured neurons from the suprachiasmatic nucleus, which is a critical center

Challenges facing quantitative large-scale optical super-resolution, and some simple solutions

Authors Dankovich TM, Rizzoli SO Journal iScience Citation iScience. 2021 Feb 3;24(3):102134. Abstract Optical super-resolution microscopy (SRM) has enabled biologists to visualize cellular structures with near-molecular resolution, giving unprecedented access to details about the amounts, sizes and spatial distributions of macromolecules in the cell. Precisely quantifying these molecular details requires

NanoSIMS observations of mouse retinal cells reveal strict metabolic controls on nitrogen turnover

Authors Bonnin EA, Fornasiero EF, Lange F, Turck CW, Rizzoli SO Journal BMC Molecular and Cell Biology Citation BMC Mol and Cell Biol 22, 5 (2021). Abstract Background Most of the cells of the mammalian retina are terminally differentiated, and do not regenerate once fully developed. This implies that these

Novel Secondary Ion Mass Spectrometry Methods for the Examination of Metabolic Effects at the Cellular and Subcellular Levels

Authors Bonnin EA, Rizzoli SO Journal Frontiers in Behavioral Neuroscience Citation Front Behav Neurosci. 2020 Jul 20;14:124. Abstract The behavior of an animal has substantial effects on its metabolism. Such effects, including changes in the lipid composition of different organs, or changes in the turnover of the proteins, have typically
