    Focal seizures are organized by feedback between neural activity and ion concentration changes

    Damiano Gentiletti, Marco de Curtis ... Piotr Suffczynski
    Biophysically realistic computational model reveals how inhibitory interneurons initiate paroxysmal discharges and how changes in the ionic concentrations shape electrographic features of human seizures.

    Inhibition of the sodium-dependent HCO3- transporter SLC4A4, produces a cystic fibrosis-like airway disease phenotype

    Vinciane Saint-Criq, Anita Guequén ... Carlos A Flores
    The reduction of bicarbonate secretion into the airways reproduces cystic fibrosis-like features, independently of chloride secretion.

    A SLC4 family bicarbonate transporter is critical for intracellular pH regulation and biomineralization in sea urchin embryos

    Marian Y Hu, Jia-Jiun Yan ... Meike Stumpp
    Cellular carbon accumulation systems are a fundamental prerequisite for biomineralization to stabilize pH and to supply inorganic carbon for CaCO3 precipitation under changing environmental conditions.

    Roles of the ClC chloride channel CLH-1 in food-associated salt chemotaxis behavior of C. elegans

    Chanhyun Park, Yuki Sakurai ... Hirofumi Kunitomo
    A ClC chloride channel protein allows neurons to interpret both temporal resolution and intensity of sensory input, which thereby contributes to an experience-dependent navigation behavior.

    Structural and functional properties of the transporter SLC26A6 reveal mechanism of coupled anion exchange

    David N Tippett, Colum Breen ... Raimund Dutzler
    The structural and functional characterization of SLC26A6 provides greater understanding of coupled versus uncoupled transport processes for the SLC26 transporter family.

    Mutations in L-type amino acid transporter-2 support SLC7A8 as a novel gene involved in age-related hearing loss

    Meritxell Espino Guarch, Mariona Font-Llitjós ... Virginia Nunes
    SLC7A8 a neutral amino acid transporter has a key role in the maintenance of hearing during aging and its absence causes early onset of hearing loss.

    Excitation of medium spiny neurons by ‘inhibitory’ ultrapotent chemogenetics via shifts in chloride reversal potential

    Stephanie C Gantz, Maria M Ortiz ... Khaled Moussawi
    Modifying membrane potential by an 'inhibitory' chloride conductance such as PSAM4-GlyR is inherently unstable because the normally low intracellular concentration of chloride is readily increased by influx of chloride.

    Flavodiiron proteins 1–to-4 function in versatile combinations in O2 photoreduction in cyanobacteria

    Anita Santana-Sanchez, Daniel Solymosi ... Yagut Allahverdiyeva
    In vivo evidence is provided indicating that Flv2/Flv4, together with Flv1/Flv3, mediate O2 photoreduction downstream of PSI in a highly coordinated manner.

    A mechano-osmotic feedback couples cell volume to the rate of cell deformation

    Larisa Venkova, Amit Singh Vishen ... Matthieu Piel
    Whether deforming cells behave as elastic balls (deforming at constant volume) or as sponges (loosing volume as they deform) depends on how fast they change their shape, because the cell volume depends on the tension of the plasma membrane.
