A broadly applicable method that faithfully preserves genetically labeled cellular structures for 3D electron microscopy (EM) and correlated light and electron microscopy (CLEM).
Quantitative 3D lattice light sheet microscopy of unperturbed cells combined with electron tomography and acute loss of function experiments reveals how dynamic ESCRT-III/Vps4 assemblies succeed in reverse membrane budding on endosomes.
Neocortical synapses in layer 4 of the human temporal lobe neocortex were quantitatively characterized, at the subcellular level, using high-end, high-resolution electron microscopy and 3D-volume reconstructions.
Repositioning the type II ryanodine receptors on the sarcoplasmic reticulum membrane is a potential new mechanism regulating their function, and therefore the strength of cardiac contraction.
Three-dimensional electron microscopy (3DEM) demonstrates the dependence on presynaptic mitochondria for vesicle mobilization as dendritic spines are silently added at P15 or synapses are silently enlarged in adults after long-term potentiation.
Mice that lack the autism susceptibility gene Semaphorin 5A show excess excitatory synapse formation in dentate granule neurons and also altered social behavior, adding to evidence that a surplus of synapses contributes to the behavioral changes observed in autism spectrum disorders.
The secretory and recycling components of neuronal dendrites, smooth endoplasmic reticulum and endosomes, were discovered to support synaptogenesis underlying a cellular mechanism of learning and memory in the developing brain.
