Bone cells exposed to physiological forces release ATP through repairable membrane injury, generating an intercellular signal that conveys the destructive potential of forces and the adaptive capacity of endangered cells.
Single synaptic vesicle imaging shows that kinetically distinct endocytic pathways are differentially regulated by calcium and temperature, and influence the fidelity of synaptic vesicle protein retrieval.
L. interrogans utilizes endocytic recycling and vesicular transport systems for transcytosis across endothelial or epithelial barrier in blood vessels or renal tubules, which contributes to spreading and transmission of leptospirosis.
Synaptophysins and gyrins dampen synaptic strength selectively at low frequencies, hinting that synaptic transmission may play a frequency filtering role in biological computation that is more general than currently envisioned.
Inhibition of C. elegans FLD-1 or Human TLCD1/2 prevents saturated fat lipotoxicity by allowing increased levels of membrane phospholipids that contain fluidizing long-chain polyunsaturated fatty acids.
Specific attachment of molecularly defined gold nanoparticles enables precise localization, critical for structural studies in vivo, of proteins of unknown structure within the cellular milieu by cryo-electron tomography.
In Drosophila oocytes, the exclusion of the scaffold protein PAR3 from the posterior cortex depends on PAR1 and endocytosis, while its anterior localisation requires microtubules and recycling endosomes.
Reducing Akt-mediated huntingtin phosphorylation decreases APP accumulation at the synapse by reducing its anterograde axonal transport and ameliorates learning and memory in a mouse model of familial Alzheimer disease.
