"Living with" -related hemiplegic migraine, a disease concept model.

Introduction: -related Hemiplegic Migraine (HM) is a rare neurological disorder distinguished by paroxysmal episodes of hemiparesis/hemiplegia with and without headache. Clinical features have been widely characterized, yet the impacts of the paroxysmal events on the patient and caregiver have not been thoroughly explored. Disease concept models are formal frameworks used to describe the lived experiences of patients and their families, offering a source for surrogate endpoints for clinical trials.

Developing a pathway to clinical trials for -related epilepsies: A patient organization perspective.

CACNA1A-related disorders are rare neurodevelopmental disorders linked to variants in the CACNA1A gene. This gene encodes the α1 subunit of the P/Q-type calcium channel Cav2.1, which is globally expressed in the brain and crucial for fast synaptic neurotransmission.

Initial neurite outgrowth in Drosophila neurons is driven by kinesin-powered microtubule sliding.

Remarkably, forces within a neuron can extend its axon to a target that could be meters away. The two main cytoskeleton components in neurons are microtubules, which are mostly bundled along the axon shaft, and actin filaments, which are highly enriched in a structure at the axon distal tip, the growth cone. Neurite extension has been thought to be driven by a combination of two forces: pushing via microtubule assembly, and/or pulling by an actin-driven mechanism in the growth cone.
