Glutamate is the major neurotransmitter that mediates a principal form of excitatory synaptic transmission in the brain. From the presynaptic terminals of neurons, glutamate is released upon exocytosis of the ...
Sensory input is generally thought to be necessary for refining and consolidating neuronal connections during brain development. We here report that cortical callosal axons in somatosensory cortex require sens...
Congenital disorders of glycosylation (CDGs) are inherited diseases caused by glycosylation defects. Incorrectly glycosylated proteins induce protein misfolding and endoplasmic reticulum (ER) stress. The most ...
Stromal interaction molecule 1 (STIM1), a Ca2+ sensor in the endoplasmic reticulum, regulates store-operated Ca2+ entry (SOCE) that is essential for Ca2+ homeostasis in many types of cells. However, if and how ST...
