Ketamine, an NMDA receptor antagonist and experimental model for schizophrenia, produces decision-making deficits in monkeys, which are predicted by a lowering of cortical excitation-inhibition balance in a spiking circuit model.
Cryo-EM structures of the gating cycle of bestrophin reveal the molecular underpinnings of activation and inactivation gating in this calcium-activated chloride channel and reveal a surprisingly wide pore.
Male C. elegans die through two distinct mechanisms – mating-induced germline activation, and potent male pheromone toxicity – but the latter is unique to males of androdioecious species (made up of hermaphrodites and males).
Single-particle cryo-electron microscopy reveals the first subnanometer structure of ATP-sensitive potassium (KATP) channels, which provides insight into the structural mechanisms of channel assembly and gating.
The high-resolution x-ray structure of an asymmetrical SeCitS dimer, present in the inward- and outward-facing state, provides a complete mechanism of substrate and ion translocation in a sodium-dependent symporter.
