The lipid type, ceramide, also has a functional role in various signaling pathways and
affects synaptic
function, although its primary role is not in the
synapse, but providing structure in cell membranes.
The type of neurotransmitter and the strength of each connection to the
synapse affect the
functioning of the recipient neuron.
The mutation, which has been found in people with ADHD, autism and bipolar disorder,
affects the
function of DAT, a protein that regulates the brain's supply of the neurotransmitter by removing excess dopamine from the
synapse, or the space between nerve cells.
Astrocytes can regulate neuronal synapses by secreting factors that
affect both
synapse formation and synaptic
function.
Aβ is believed to penetrate neuronal plasma membranes, where it leads to lipid peroxidation.10 It has also been implicated in deactivating a subunit of the pyruvate dehydrogenase complex, thereby inhibiting conversion of pyruvate to acetyl CoA and the eventual production of cellular energy as ATP.32 Another way Aβ
affects glucose metabolism in the brain is that fragments of Aβ disrupt insulin signaling by binding to neuronal synapses, which alters their shape and
function.15, 38 Insulin receptors are abundant at synapses, so if the integrity of the
synapse itself has been compromised, the receptors won't
function effectively.
