Endosomal sorting protein SNX4 limits synaptic vesicle docking and release.

Sorting nexin 4 (SNX4) is an evolutionary conserved organizer of membrane recycling. In neurons, SNX4 accumulates in synapses, but how SNX4 affects synapse function remains unknown. We generated a conditional SNX4 knock-out mouse model and report that SNX4 cKO synapses show enhanced neurotransmission during train stimulation, while the first evoked EPSC was normal.

KIF5A regulates axonal repair and time-dependent axonal transport of SFPQ granules and mitochondria in human motor neurons.

Mutations in the microtubule-binding motor protein kinesin 5 A (KIF5A) are implicated in several adult-onset motor neuron diseases, including Amyotrophic Lateral Sclerosis, Spastic Paraplegia Type 10 and Charcot-Marie-Tooth Disease Type 2. While KIF5 family members transport a variety of cargos along axons, the specific cargos affected by KIF5A mutations remain poorly understood. Here, we generated KIF5Anull mutant human motor neurons and analyzed the impact on axonal transport and motor neuron outgrowth and regeneration in vitro.

The role of childhood trauma and attachment state of mind in mothers' birth experiences.

Negative birth experiences are common. It is yet unclear which women may be most at risk already before pregnancy. Childhood trauma and non-autonoumous/unresolved attachment state of mind may affect how women experience giving birth.

KIF5A regulates axonal repair and time-dependent axonal transport of SFPQ granules and mitochondria in human motor neurons.

Mutations in the microtubule binding motor protein, kinesin family member 5A (KIF5A), cause the fatal motor neuron disease, Amyotrophic Lateral Sclerosis. While KIF5 family members transport a variety of cargos along axons, it is still unclear which cargos are affected by mutations. We generated null mutant human motor neurons to investigate the impact of KIF5A loss on the transport of various cargoes and its effect on motor neuron function at two different timepoints .
