A single subpopulation of photoreceptors constitutes a shared node in the neural networks that regulate light-dependent maturation of the circadian clock and light-independent refinement of retinal ganglion cell projections to the brain.
Second-order guidance, a novel mechanism by which an initial guidance cue controls expression of a second guidance receptor, is required for precise refinement of axon trajectories during PNS development.
Advances in techniques for analysing single cells and tissues have inspired an international effort to create comprehensive reference maps of all human cells - the fundamental units of life - as a basis for both understanding human health and diagnosing, monitoring and treating disease.
The helical rod structure and dynamic spring-like properties of the type 1 pilus are evolutionarily fine-tuned for functioning in host-pathogen interactions during urinary tract infection and gut colonization.
The organization of layered/laminated axon projections in specific regions of the fruitfly central brain is regulated by short-range repulsive guidance and is critical for local inhibitory circuit formation and function.
The somatosensory cortex doesn't integrate mixed bilateral inputs, as partially uncrossing projections from the whiskers duplicates their representation by segregating lateralized inputs from each side of the head.
The coding sequences of a very highly conserved family of neurogenic transcription factors from different species have evolved to generate proteins that have different life times causing them to display quantitatively different neural induction potentials.
