Single-nociceptor tracing reveals a novel somatotopic organization for the mammalian pain system, and physiological recordings and peripheral optogenetic behavior assays suggest that it is a possible mechanism underlying region-specific pain sensation.
The APP intracellular domain (AICD) physiologically regulates synaptic GluN2B-containing NMDA receptor current, a process that could contribute to pathological Alzheimer's disease-related synaptic failure upon increase of AICD levels in adult neurons.
Transport-based high-throughput identification of cargo proteins specific to all 12 human importin-β family nuclear import receptors revealed biological processes that the cargo cohorts of each receptor are involved in.
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.
A newly characterized calcium-activated chloride channel has been implicated in the immune system of Drosophila, shedding light on an enigmatic family of transmembrane proteins that are ubiquitous in nature.
