Phosphodiesterase-4 (PDE4) plays an important role in mediating memory via the control of intracellular cAMP signaling; inhibition PDE4 enhances memory. However, development inhibitors as enhancers has been hampered by their major side effect emesis. four subtypes (PDE4A–D) consisting 25 splice variants. Mice deficient PDE4D displayed enhancement radial arm maze, water and object recognition tests. These effects were mimicked repeated treatment with rolipram wild-type mice. In addition,...

Neuroinflammation often results in enduring cognitive impairment and is a risk factor for postoperative dysfunction. There are currently no effective treatments infection-induced impairment. Previous studies have shown that the iron chelator deferoxamine (DFO) can increase resistance of neurons to injury disease by stimulating adaptive cellular stress responses. However, impact DFO on sequelae neuroinflammation unknown. A mouse model lipopolysaccharide (LPS)-induced was established evaluate...
