    Bax and Bak function as the outer membrane component of the mitochondrial permeability pore in regulating necrotic cell death in mice

    Jason Karch et al.
    The proteins Bax and Bak, which increase the permeability of the mitochondrial membrane during apoptosis, are also crucial for generating a mitochondrial membrane pore that is specifically involved in necrosis.

    Acyl chain asymmetry and polyunsaturation of brain phospholipids facilitate membrane vesiculation without leakage

    Marco M Manni et al.
    The asymmetric combination of saturated and polyunsaturated acyl chains in phospholipids as typically observed in synapses makes membranes prone to deformation and fission without compromising their impermeability.

    Autophagic cell death is dependent on lysosomal membrane permeability through Bax and Bak

    Jason Karch et al.
    Molecular pathways controlling autophagic cell death are regulated at the level of the lysosome through the activity of the pro-death Bcl-2 family member Bax/Bak.

    Magnetic resonance measurements of cellular and sub-cellular membrane structures in live and fixed neural tissue

    Nathan H Williamson et al.
    Low-field single-sided magnetic resonance diffusion methods detect and measure permeability of sub-micron compartments which likely include cell processes, organelles, and cellular vesicles within ex vivo mouse spinal cords.

    Atomistic simulations indicate the c-subunit ring of the F1Fo ATP synthase is not the mitochondrial permeability transition pore

    Wenchang Zhou et al.
    The notion that the lumen of the ATP synthase membrane rotor is the long-sought megachannel that triggers the onset of the mitochondrial permeability transition is found to be inconsistent with its actual structural and functional properties.

    Two-component Signaling Pathways: A bacterial Goldilocks mechanism

    Irene M Kim, Hendrik Szurmant
    Bacillus subtilis can measure the activity of the enzymes that remodel the cell wall to ensure that the levels of activity are ‘just right’.

    Apolipoprotein M-bound sphingosine-1-phosphate regulates blood–brain barrier paracellular permeability and transcytosis

    Mette Mathiesen Janiurek et al.
    Shortage of blood-borne apolipoprotein-M–bound sphingosine-1-phosphate, which accompanies various brain disorders, causes paracellular leak and increase in transcytosis at the blood–brain barrier, which can be reversed, thus is of clinical relevance.

    Symmetry transitions during gating of the TRPV2 ion channel in lipid membranes

    Lejla Zubcevic et al.
    Ligand-induced two-fold symmetric arrangement in TRPV2 is observed in the native-like nanodisc-reconstituted condition using cryo-electron microscopy.
