Persistent pain induced by noxious stimuli is characterized by the transition from normosensitivity to hypersensitivity. Underlying mechanisms are not well understood, although gene expression is considered important. Here, we show that persistent nociceptive-like activity triggers calcium transients in neuronal nuclei within the superficial spinal dorsal horn, and that nuclear calcium is necessary...
The role of neuronal dendrites is to receive and process synaptic inputs. The geometry of the dendritic arbor can undergo neuronal activity-dependent changes that may impact the cognitive abilities of the organism. Here we show that vascular endothelial growth factor D (VEGFD), commonly known as an angiogenic mitogen, controls the total length and complexity of dendrites both in cultured hippocampal...
Nuclear calcium is a key signal in the dialogue between synapse and nucleus that controls the genomic responses required for persistent adaptations, including memory and acquired neuroprotection. The amplitude and duration of nuclear calcium transients specify activity-induced transcriptional changes. However, the precise relationship between synaptic input and nuclear calcium output is unknown. Here,...
