Owing to their phylogenetic position , cartilaginous fishes ( sharks , rays , skates , and chimaeras ) provide a critical reference for our understanding of vertebrate genome evolution .

DNA damage resulting from intrinsic or extrinsic sources activates DNA damage responses ( DDRs ) centered on protein kinase signaling cascades . The usual consequences of inducing DDRs include the activation of cell cycle checkpoints together with repair of the damaged DNA or induction of apoptosis . Many DNA viruses e... | As intracellular parasites , viruses often redirect cellular pathways to facilitate their own replication . Infection by DNA viruses often lead to the activation of host DNA damage response pathways , which normally function to repair damage to host chromosomes .

Spike-timing-dependent plasticity ( STDP ) , a form of Hebbian plasticity , is inherently stabilizing . Whether and how GABAergic inhibition influences STDP is not well understood . Using a model neuron driven by converging inputs modifiable by STDP , we determined that a sufficient level of inhibition was critical to ... | Evidence suggests that maturation of inhibition is required for the development of plasticity to proceed in the visual cortex . However , the mechanisms by which increased inhibition promotes plasticity are not clear . Here we characterized the maturation of synaptic and intrinsic ionic properties of parvalbumin-positi... | [
