Increases of extracellular potassium silence capillary pericyte calcium signaling, suggesting a participation of capillary pericytes in the potassium-mediated neurovascular communication.

Naturally occurring activity in the developing brain regulates mitochondrial motility such that mitochondria stop at active synapses, which is probably a fundamental process in brain wiring.

Two niches contribute to the control of Drosophila blood cell homeostasis through their differential regulation of hematopoietic progenitors.

NG2 glial cells respond to synaptic input with calcium signals in the absence of action potentials and process synaptic depolarizations with somatic and dendritic voltage gated channels.

Sphingosine acts as a lipid messenger molecule in intracellular signaling networks that are relevant to lysosomal function and Niemann-Pick disease.

High-speed calcium imaging from the axon initial segment shows that sodium channels are in part permeable to calcium ions.

Hair cell survival and mitochondrial function is supported by an extracellular stimulator of IGF1 signaling, the protease pregnancy-associated plasma protein-aa.

Controlling the duration of ligand binding to the T cell receptor by light shows that T cells discriminate stimulatory from non-stimulatory ligands by measuring the dynamics of ligand binding.

Lasso and latrophilin-1 interact across the synapse, while shed Lasso binds latrophilin-1 on distant growth cones and attracts them, providing a universal mechanism for short- and long-range axonal guidance.

Calcium-calcineurin signaling cascade drives the acquisition of both the phenotype of the most self-reactive naive CD4 T cells and their enhanced cell-intrinsic ability to commit into induced regulatory T cells upon activation.
