These results indicate that, although miR-34a overexpressing neurons have lower basal level of GluR1, they respond to a synaptic stimulus more efficiently than control neurons.
It is well known that there is a basal level of extracellular adenosine that tonically exerts a presynaptic inhibition of synaptic transmission.
The frequency of spontaneous reversals during locomotion has thus been used in behavioural assays to test the strength of glutamatergic synaptic transmission [ 30, 31] and has been shown to be regulated presynaptically by the basal level of activation and firing of ASH and other sensory neurons and postsynaptically by the concentration of glutamate receptors [ 29, 30, 32, 33].
If we apply antiperspirant in the morning, our basal level of sweat production is a bit too high, she says.
Specifically, we hypothesized that olfactory neurons would utilize basal levels of Ten-a and Ten-m to control synaptic number.
In this model, basal glutamatergic neurotransmission sensed by cortical GluN2B-containing NMDARs regulates excitatory synaptic strength in PFC determining basal levels of depression-like behavior.
In summary, our data suggest a novel mechanistic model for the antidepressant actions of ketamine that involves tonic activation of GluN2B-containing NMDARs in helping set basal levels of despair through regulation of protein synthesis and excitatory synaptic drive in PFC.
Western blot analysis showed the presence of mTOR in synaptoneurosomes as well as basal levels of phosphorylated protein (p-mTOR) and expression of BDNF, Rheb, and the synaptic proteins, SAP-102, GluA1, and GluA2.
To measure basal levels of signaling in the resting, unmodulated state, the "Basal" metric was applied.
