Tonic immobility in two species of Southern African catsharks [PDF]

open access: yes, 2020
Magister Scientiae (Biodiversity and Conservation Biology) - MSc (Biodiv and Cons Biol)Tonic immobility (TI) can be defined as an unlearned behavioural response described by a physical state of immobility. This behaviour can last from a few seconds up to

Pharmacological analysis of the activation and receptor properties of the tonic GABA(C)R current in retinal bipolar cell terminals.

open access: yesPLoS ONE, 2011
GABAergic inhibition in the central nervous system (CNS) can occur via rapid, transient postsynaptic currents and via a tonic increase in membrane conductance, mediated by synaptic and extrasynaptic GABA(A) receptors (GABA(A)Rs) respectively.

Tonic excitation or inhibition is set by GABAA conductance in hippocampal interneurons [PDF]

open access: yesNature Communications, 2011
Inhibition is a physiological process that decreases the probability of a neuron generating an action potential. The two main mechanisms that have been proposed for inhibition are hyperpolarization and shunting. Shunting results from increased membrane conductance, and it reduces the neuron-firing probability.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Regulation of output spike patterns by phasic inhibition in cerebellar granule cells

open access: yesFrontiers in Cellular Neuroscience, 2014
The complex interplay of multiple molecular mechanisms taking part to synaptic integration is hard to disentangle experimentally. Therefore, we developed a biologically realistic computational model based on the rich set of data characterizing the ...

Transient mTOR inhibition rescues 4-1BB CAR-Tregs from tonic signal-induced dysfunction

open access: yesNature Communications, 2021
Chimeric antigen receptor engineering in T cells has been shown to be of great potential therapeutic benefit in a range of immune pathologies, although the functionality of such cell therapies can be limited due to tonic signalling and the induction of ...

Pathophysiological role of extrasynaptic GABAA receptors in typical absence epilepsy [PDF]

open access: yes, 2011
GABA is the principal inhibitory neurotransmitter in the mammalian CNS. It acts via two classes of receptors, the GABAA, a ligand gated ion channel (ionotropic receptor) and the metabotropic G-protein coupled GABAB receptor.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

open access: yesMolecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Tonic zinc inhibits spontaneous firing in dorsal cochlear nucleus principal neurons by enhancing glycinergic neurotransmission

open access: yesNeurobiology of Disease, 2015
In many synapses of the CNS, mobile zinc is packaged into glutamatergic vesicles and co-released with glutamate during neurotransmission. Following synaptic release, the mobilized zinc modulates ligand- and voltage-gated channels and receptors ...
