The three-dimensional structures of 50 sensory cilia present in the head of the adult C. elegans hermaphrodite have been reconstructed to provide a foundation for investigations into the mechanisms by which the diversity of cilia structures is generated and how this structural diversity is related to specific sensory neuron functions.
Respiratory activity and inner membrane organisation of mitochondria from Drosophila melanogaster break down during ageing, but mouse heart mitochondria appear to be protected against age-related damage.
Proteins of the reticulon and REEP families, homologous to the products of human Hereditary Spastic Paraplegia disease genes, contribute to shaping and continuity of the axonal endoplasmic reticulum network in Drosophila.
A new biophysical model enables the reconciliation of ultrastructural and tissue level measurements on parameters affecting intercellular communication, and provides novel functional insight into experimental findings.
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.
Heterogeneous epidermal stem cells define a niche for tactile sensation via providing a unique ECM and tissue architecture for nerves, revealing their new functions in coordinated sensory organ formation.
