Ferroptosis is an evolutionary ancient process that is counterbalanced by distant peroxidases, GPx4 in mammals and tryparedoxin peroxidases in trypanosomes, and can be induced at distinct subcellular membranes depending on the individual cell type.
The organization of layered/laminated axon projections in specific regions of the fruitfly central brain is regulated by short-range repulsive guidance and is critical for local inhibitory circuit formation and function.
In C. elegans, presenilin functions, independent of its gamma-secretase proteolytic activity, to regulate mitochondrial metabolism by controlling ER-mitochondrial calcium transfer and, even in the absence of Abeta signaling, loss of this activity leads to neurodegeneration.
Reactive oxygen species, previously considered damaging agents linked to pathology, are required for normal neuronal plasticity, including adjustment of synaptic terminal size, maintenance of synaptic physiology and adaptive behavioural responses.
The structure of the catalytic core of the N6-methyladenosine RNA methyltransferase complex METTL3-METTL14 reveals that METTL3 is the catalytic subunit, while METTL14 plays non-catalytic roles in substrate recognition and in maintaining complex integrity.
In mouse models of Huntington's disease, the subthalamic nucleus, which suppresses movements, also exhibits impaired glutamate homeostasis, NMDA receptor-dependent mitochondrial oxidant stress, firing disruption, and 30% neuronal loss.
Phosphoproteomics identifies β-arrestin 2 phosphorylation at Thr383 by MEK as a key step of GPCR-induced Erk½ activation, thus providing new insight into the molecular mechanism underlying β-arrestin-dependent GPCR-operated signaling.
Adapting a cytosolic enzyme that breaks down glutathione to function in the lumen of the endoplasmic reticulum challenges the long-held view that reduced glutathione fuels disulfide rearrangements during protein folding.
The human cytomegalovirus (HCMV) interactome systematically characterises high-confidence viral-viral and viral-host protein interactions in HCMV-infected cells, facilitating multiple novel insights into HCMV and herpesviral function.
