NBCe1 mediates the acute stimulation of astrocytic glycolysis by extracellular K+

…, R Gutiérrez, G Peña-Münzenmayer… - Journal of …, 2011 - Soc Neuroscience
Excitatory synaptic transmission stimulates brain tissue glycolysis. This phenomenon is the
signal detected in FDG-PET imaging and, through enhanced lactate production, is also …

Basolateral localization of native ClC-2 chloride channels in absorptive intestinal epithelial cells and basolateral sorting encoded by a CBS-2 domain di-leucine motif

G Peña-Münzenmayer, M Catalán… - Journal of Cell …, 2005 - journals.biologists.com
The Cl – channel ClC-2 is expressed in transporting epithelia and has been proposed as an
alternative route for Cl – efflux that might compensate for the malfunction of CFTR in cystic …

[HTML][HTML] Separate gating mechanisms mediate the regulation of K2P potassium channel TASK-2 by intra-and extracellular pH

MI Niemeyer, LP Cid, G Peña-Münzenmayer… - Journal of biological …, 2010 - ASBMB
TASK-2 (KCNK5 or K 2P 5.1) is a background K + channel that is opened by extracellular
alkalinization and plays a role in renal bicarbonate reabsorption and central chemoreception. …

A fluid secretion pathway unmasked by acinar-specific Tmem16A gene ablation in the adult mouse salivary gland

…, Y Kondo, G Peña-Munzenmayer… - Proceedings of the …, 2015 - National Acad Sciences
Activation of an apical Ca 2+ -activated Cl − channel (CaCC) triggers the secretion of saliva.
It was previously demonstrated that CaCC-mediated Cl − current and Cl − efflux are absent …

Ae4 (Slc4a9) is an electroneutral monovalent cation-dependent Cl/HCO3 exchanger

G Peña-Münzenmayer, AT George, GE Shull… - Journal of General …, 2016 - rupress.org
Ae4 (Slc4a9) belongs to the Slc4a family of Cl − /HCO 3 − exchangers and Na + -HCO 3 −
cotransporters, but its ion transport cycle is poorly understood. In this study, we find that native …

G protein modulation of K2P potassium channel TASK-2: A role of basic residues in the C terminus domain

C Añazco, G Peña-Münzenmayer, C Araya… - … -European Journal of …, 2013 - Springer
TASK-2 (K 2P 5.1) is a background K + channel opened by extra- or intracellular alkalinisation

[HTML][HTML] Ae4 (Slc4a9) anion exchanger drives Cl− uptake-dependent fluid secretion by mouse submandibular gland acinar cells

G Peña-Münzenmayer, MA Catalán, Y Kondo… - Journal of Biological …, 2015 - ASBMB
Transcellular Cl − movement across acinar cells is the rate-limiting step for salivary gland
fluid secretion. Basolateral Nkcc1 Na + -K + -2Cl − cotransporters play a critical role in fluid …

Ca2+-dependent K+ channels in exocrine salivary glands

MA Catalán, G Peña-Munzenmayer, JE Melvin - Cell calcium, 2014 - Elsevier
In the last 15 years, remarkable progress has been realized in identifying the genes that
encode the ion-transporting proteins involved in exocrine gland function, including salivary …

A mathematical model supports a key role for Ae4 (Slc4a9) in salivary gland secretion

…, MA Catalán, G Peña-Münzenmayer… - Bulletin of mathematical …, 2018 - Springer
We develop a mathematical model of a salivary gland acinar cell with the objective of
investigating the role of two $$\mathrm{Cl}^-/\mathrm{HCO}_3^-$$ Cl - / HCO 3 - exchangers from …

Zebrafish and mouse TASK-2 K+ channels are inhibited by increased CO2 and intracellular acidification
