The ability of the eye of a fruit fly (Drosophila melanogaster) to respond to light depends on a delicate ballet that keeps the supply of light sensors called rhodopsin constant as photoreceptors turn on and off in response to light exposures.
A collaboration by an international consortium of researchers led by scientists at Baylor College of Medicine and the Montreal Neurological Institute of McGill University have linked the discovery of a mutation in a mitochondrial gene in fruit flies that causes the loss of neurologic function (a neurodegenerative set of characteristics or phenotype) and a progressive recessively inherited ataxia or neurodegenerative disorder in humans.
A collaborative study by scientists at Baylor College of Medicine (BCM) and the Montreal Neurological Institute of McGill University, and published March 20 in the online, open access journal PLoS Biology, has discovered that mutations in the same gene that encodes part of the vital machinery of the mitochondrion can cause neurodegenerative disorders in both fruit flies and humans.
The transmission of information from one neuron to the next is an unseen intricate ballet.
As part of the intricate ballet of synaptic transmission from one neuron to the next, tiny vesicles â€“ bubbles containing the chemical neurotransmitters that make information exchange possibleâ€”travel to the tip of neurons (synapses), where they fuse with the cell's membrane (a process called exocytosis).
Recycling is a critical component in the process of transmitting information from one neuron to the next, and a large protein called Tweek plays a critical role, said an international consortium of researchers led by Baylor College of Medicine (www.bcm.edu) in a report in the current issue of the journal Neuron.
Notch signaling helps determine the fate of a number of different cell types in a variety of organisms, including humans.
Using a specially adapted tool called P[acman], a collaboration of researchers led by Baylor College of Medicine has established a library of clones that cover most of the genome of Drosophila melanogaster (fruit fly) and should speed the pace of genetic research.
