NATURE NEUROSCIENCE: DREADDs and PSAMs interrogate memory

PV plasticity , which involves changes in PV and GAD67 expression and connectivity onto PV neurons, was regulated by cAMP signaling in PV neurons. ... Our results reveal general network mechanisms of long-term memory consolidation that requires plasticity of PV basket cells induced after acquisition and sustained subsequently through D1/5 receptor signaling.

DREADDs therapeutically modulate experimental Alzheimer's Disease

DREADDs and optogenetics to deconstruct opioid modulation of inputs to PAG

Nice paper recently published. Intriguingly the inputs when activated modulated hot plate but not tail flick nor locomotor activity.

NATURE COMMUNICATIONS: DREADDs to deconstruct Gs vs Gq signaling and feeding

Very complete and compelling paper Here we show that the activation of G s -coupled receptors expressed by AgRP neurons leads to a robust and sustained increase in food intake. We also provide detailed mechanistic data linking the stimulation of this class of receptors to the observed feeding phenotype. Moreover, we show that this pathway is clearly distinct from other GPCR signalling cascades that are operative in AgRP neurons. Our data suggest that drugs able to inhibit this signalling pathway may become useful for the treatment of obesity.
