    Proximal clustering between BK and CaV1.3 channels promotes functional coupling and BK channel activation at low voltage

    Oscar Vivas et al.
    Super-resolution imaging reveals a novel multi-channel arrangement that explains how big potassium (BK) channel activation closely tracks the opening of low-voltage-activated L-type calcium channels.

    Mechanical sensitivity of Piezo1 ion channels can be tuned by cellular membrane tension

    Amanda H Lewis, Jörg Grandl
    Tension is the activating stimulus of Piezo1 mechanosensitive ion channels and resting membrane tension modulates overall channel sensitivity to mechanical stimulation.
