The calcium-binding protein parvalbumin modulates the firing 1 properties of the reticular thalamic nucleus bursting neurons

Albéri, Lavinia ; Lintas, Alessandra ; Kretz, Robert ; Schwaller, Beat ; Villa, Alessandro E. P.

In: Journal of Neurophysiology, 2013, vol. 109, no. 11, p. 2827–2841

The reticular thalamic nucleus (RTN) of the mouse is characterized by an overwhelming majority of GABAergic neurons receiving afferences from both the thalamus and the cerebral cortex and sending projections mainly on thalamocortical neurons. The RTN neurons express high levels of the “slow Ca²⁺ buffer” parvalbumin (PV) and are characterized by low-threshold Ca²⁺ currents,...

Upregulated expression of oncomodulin, the beta isoform of parvalbumin, in perikarya and axons in the diencephalon of parvalbumin knockout mice

Csillik, B. ; Schwaller, Beat ; Mihaly, A. ; Henzi, Thomas ; Losonczi, E. ; Knyihar-Csillik, E.

In: Neuroscience, 2010, vol. 165, no. 3, p. 749-757

The calcium-binding proteins parvalbumin, calbindin D-28k, calretinin and calcineurin are present in subsets of GABAergic gigantic calyciform presynaptic terminals of the reticular thalamic nucleus (RTN). Previously it was hypothesized that GABA and calcium-binding proteins including parvalbumin are not only colocalized in the same neuron subpopulation, but that GABA synthesis and parvalbumin...
