Calcium channels

Calcium channels are ion channels that are triggered to open by either a change in the voltage across the membrane, which occurs in nerve cells propagating a signal, or by small molecule ligands such as inositol 1,4,5-trisphosphate (Ins3P, IP3). Calcium channels allow calcium to flow into the cell or out of the endoplasmic reticulum.

    Piezo channels are mechanosensitive and rely on membrane composition to transduce physical stimuli into electrical signals. Here authors analyse the membrane components that modulate Piezo1 function using lipid profiling which shows that fatty acid metabolism can modulate ion channel activity.

    Two-photon absorption capacity of azobenzene photoswitches usually comes with a reduction in thermal stability. Here, the authors developed photoswitches with high two-photon sensitivity and enhanced cis isomer thermal lifetime for the control of glutamate receptors.

    Regulated calcium signalling, in particular downstream of the T cell receptor, is crucial for many T cell effector functions. This Review provides an overview of the numerous membrane and organellar calcium-permeable channels that are coordinated to fine-tune T cell immunity.

    Giant cell lesions of the jaw (GCLJ) are debilitating benign tumors of unclear origin. The authors identify driver recurrent somatic mutations in TRPV4, KRAS and FGFR1 and show they converge on aberrant activation of the MAPK pathway. Their findings extend the spectrum of TRPV4 channelopathies and provide rationale for targeted therapies at the bedside in GCLJ.
