Tackling the Dynamic Range Problem of Hearing: Diverse Hair Cell Synapses Enable Broad Neural Sound Intensity Coding

Authors Jaime Tobón LM, Moser T Journal Cell Reports Citation Cell Rep, 2022. under review. Abstract Synaptic heterogeneity can expand the encoding capacity of individual neurons or sensory cells. The afferent synapses between inner hair cells (IHCs) and spiral ganglion neurons (SGNs) in the cochlea exhibit marked heterogeneity in structure

The TFAM-to-mtDNA ratio defines inner-cellular nucleoid populations with distinct activity levels

Authors Brüser C, Keller-Findeisen J, Jakobs S Journal Cell Reports Citation Cell Reports 37, 110000, November 23, 2021. Abstract In human cells, generally a single mitochondrial DNA (mtDNA) is compacted into a nucleoprotein complex denoted the nucleoid. Each cell contains hundreds of nucleoids, which tend to cluster into small groups.

Multi-label in vivo STED microscopy by parallelized switching of reversibly switchable fluorescent proteins

Authors Willig KI, Wegner W, Müller A, Calvet-Fournier V, Steffens H Journal Cell Reports Citation Cell Reports. 2021 Jun 1; 35 (9) 109192. Abstract Despite the tremendous success of super-resolution microscopy, multi-color in vivo applications are still rare. Here we present live-cell multi-label STED microscopy in vivo and in vitro

Presynaptic activity and protein turnover are correlated at the single-synapse level

Authors Jähne S, Mikulasch F, Heuer HGH, Truckenbrodt S, Agüi-Gonzalez P, Grewe K, Vogts A, Rizzoli SO, Priesemann V Journal Cell Reports Citation Cell Reports 34, 108841, March 16, 2021. Abstract Synaptic transmission relies on the continual exocytosis and recycling of synaptic vesicles. Aged vesicle proteins are prevented from recycling

Vesicular Glutamate Transporters (SLCA17 A6, 7, 8) Control Synaptic Phosphate Levels

Authors Cheret C, Ganzella M, Preobraschenski J, Jahn R, Ahnert-Hilger G Journal Cell Reports Citation Cell Rep. 2021 Jan 12;34(2):108623. Abstract Vesicular glutamate transporters (VGLUTs) fill synaptic vesicles with glutamate. VGLUTs were originally identified as sodium-dependent transporters of inorganic phosphate (Pi), but the physiological relevance of this activity remains unclear.

Ultrastructural Correlates of Presynaptic Functional Heterogeneity in Hippocampal Synapses

Authors Maus L, Lee C, Altas B, Sertel SM, Weyand K, Rizzoli SO, Rhee J, Brose N, Imig C, Cooper BH Journal Cell Reports Citation Cell Rep. 2020 Mar 17;30(11):3632-3643.e8. Abstract Purpose: Although similar in molecular composition, synapses can exhibit strikingly distinct functional transmitter release and plasticity characteristics. To determine
