    Epithelial magnesium transport by TRPM6 is essential for prenatal development and adult survival

    Vladimir Chubanov et al.
    Mice deficient in the TRPM6 channel suffer from impaired prenatal development, shortened lifespan, growth deficit and disturbed energy balance due to a defect in epithelial Mg2+ uptake, thus highlighting a pivotal role of TRPM6 in organismal Mg2+ homeostasis.

    Anti-nociceptive action of peripheral mu-opioid receptors by G-beta-gamma protein-mediated inhibition of TRPM3 channels

    Sandeep Dembla et al.
    Pro-nociceptive and pro-inflammatory TRPM3 (transient receptor potential melastatin 3) channels, expressed in somatosensory neurons, are inhibited by activation of Gαi-coupled receptors, such as µ-opioid receptors, in vitro and in vivo.

    TRPM5-mediated calcium uptake regulates mucin secretion from human colon goblet cells

    Sandra Mitrovic et al.
    Goblet cells secrete mucins—which are key components of mucus—in a process that is regulated by calcium ions, which enter the goblet cells via a mechanism involving a channel protein called TRPM5.

    Disease-associated mutations in the human TRPM3 render the channel overactive via two distinct mechanisms

    Siyuan Zhao et al.
    Disease-associated mutants of the TRPM3 ion channel are overactive, and they are inhibited by the antiepileptic medication primidone, offering a potential therapeutic intervention to treat this channelopathy.

    Ligand recognition and gating mechanism through three ligand-binding sites of human TRPM2 channel

    Yihe Huang et al.
    High-resolution structures of human TRPM2 in different functional states provided the mechanism underlying ligand recognition, channel activation and inhibition.

    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.

    Molecular mechanism of TRPV2 channel modulation by cannabidiol

    Ruth A Pumroy et al.
    Cannabidiol binds to TRPV2 via a previously unidentified, but highly conserved, pocket.

    Selective agonist of TRPML2 reveals direct role in chemokine release from innate immune cells

    Eva Plesch et al.
    Direct and selective activation of TRPML2 promotes macrophage migration through release of CCL2.
    1. Neuroscience

    Microglia TREM2R47H Alzheimer-linked variant enhances excitatory transmission and reduces LTP via increased TNF-α levels

    Siqiang Ren et al.
    Analysis of rats carrying the microglia gene and Alzheimer risk factor Trem2R47H variant shows increased glutamatergic transmission via supraphysiological TNF-α brain concentrations, linking a microglia pathogenic variant to neuronal dysfunction.
    1. Neuroscience

    Gain of channel function and modified gating properties in TRPM3 mutants causing intellectual disability and epilepsy

    Evelien Van Hoeymissen et al.
    Two mutations in TRPM3 resulting in developmental and epileptic encephalopathies result in a gain-of-channel function, which may lie at the basis of epileptic activity and neurodevelopmental symptoms in the patients.
