In this publication, under the title of «Membrane - Derived Phospholipids
Control Synaptic Neurotransmission and Plasticity», the Cadiz scientists have reflected the work of years that has led them to identify a molecule, Lysophosphatidic acid (LPA), as a possible element implicated in the link between the metabolic state of an organism and its cerebral
function.
This regulation is spectacularly apparent in the exquisite speed and precision of
synaptic exocytosis, where synaptotagmin (the calcium - ion sensor for fusion) cooperates with complexin (the clamp activator) to
control the precisely timed release of neurotransmitters that initiates
synaptic transmission and underlies brain
function.
We also conduct electrophysiological, biochemical, imaging, antd behavioral studies with various knockout and transgenic mice to determine how precise genetic manipulations that either activate or abolish specific translational
control mechanisms alter
synaptic function and behavior.
We will explore the
function of these genes in
controlling synaptic homeostasis, develop novel imaging approaches to visualize homeostatic changes in real time, and systematically screen genes implicated in aging and longevity for roles in homeostatic plasticity.
Homeostatic
control of
synaptic function has been demonstrated in diverse organisms, including flies, rodents, and humans, yet the genes and molecular mechanisms governing these processes remain unclear.
In order to analyze the
function of individual proteins in neuronal circuits or
synaptic remodeling, researchers combine the Cre and FLP recombinases to
control both knockout of a target gene and expression of a separate gene.
He also studies how dysregulated translational
control contributes to altered
synaptic function and aberrant behaviors in developmental brain disorders and neurodegenerative disease.
