Catecholamine-stimulated cyclic GMP accumulation in the rat pineal: apparent presynaptic site of action.

abstract：:Emerging genetic and clinical evidence suggests a link between Gaucher disease and the synucleinopathies Parkinson disease and dementia with Lewy bodies. Here, we provide evidence that a mouse model of Gaucher disease (Gba1(D409V/D409V)) exhibits characteristics of synucleinopathies, including progressive accumulation...
