Compound ITH33/IQM9.21 (ITH/IQM) belongs to a new family of l-glutamic acid derivatives with antioxidant and neuroprotective properties on in vitro and in vivo models of stroke. Because neuronal damage after brain ischemia is tightly linked to excess Ca2+ entry and neuronal Ca2+ overload, we have investigated whether compound ITH/IQM antagonises the(More)
Modifications in Ca2+ influx may lead to profound changes in the cell activity associated with Ca2+-dependent processes, from muscle contraction and neurotransmitter release to calcium-mediated cell death. Therefore, calcium entry into the cell requires fine regulation. In this context, understanding of the modulation of voltage-dependent Ca2+ channels(More)
We investigated the effects of muscarinic acetylcholine receptor (mAChR) activation on GABAergic synaptic transmission in rat hippocampal neurons. Current-clamp recordings revealed that methacholine produced membrane depolarization and action potential firing. Methacholine augmented the bicuculline-sensitive and GABA(A) -mediated frequency of spontaneous(More)
It is currently known that in CNS the extracellular matrix is involved in synaptic stabilization and limitation of synaptic plasticity. However, it has been reported that the treatment with chondroitinase following injury allows the formation of new synapses and increased plasticity and functional recovery. So, we hypothesize that some components of(More)
We characterized the ionic currents underlying the cellular excitability and the Ca(2+) -channel subtypes involved in action potential (AP) firing of rat adrenal chromaffin cells (RCCs) preserved in their natural environment, the adrenal gland slices, through the perforated patch-clamp recording technique. RCCs prepared from adrenal slices exhibit a resting(More)
Taurine is one of the most abundant free amino acids in the central nervous system, where it displays several functions. However, its molecular targets remain unknown. It is well known that taurine can activate GABA-A and strychnine-sensitive glycine receptors, which increases a chloride conductance. In this study, we describe that acute application of(More)
Choline is present at cholinergic synapses as a product of acetylcholine degradation. In addition, it is considered a selective agonist for α5 and α7 nicotinic acetylcholine receptors (nAChRs). In this study, we determined how choline affects action potentials and excitatory synaptic transmission using extracellular and intracellular recording techniques in(More)
