In normal aging, the mammalian cortex undergoes significant remodeling. Although neuromodulation by dopamine and noradrenaline in the cortex is known to be important for proper cognitive function, little is known on how cortical noradrenergic and dopaminergic presynaptic boutons are affected in normal aging. Using rats we investigated whether these two(More)
Inositol phosphate kinases (IPKs) sequentially phosphorylate inositol phosphates (IPs) to yield a group of small signaling molecules involved in diverse cellular processes. IPK1 (inositol 1,3,4,5,6-pentakisphosphate 2-kinase) phosphorylates inositol 1,3,4,5,6-pentakisphosphate to inositol 1,2,3,4,5,6-hexakisphosphate; however, the mechanism of IP(More)
