From: Reduced cGMP levels in CSF of AD patients correlate with severity of dementia and current depression
cGMP, but not cAMP, levels in CSF of AD patients are reduced. Box plots comparing CSF levels of cGMP (a) and cAMP (b) in CSF of patients with AD compared with control patients measured by ELISA. (a) cGMP levels in the CSF of AD patients were significantly reduced compared with control subjects (p = 0.017). (b) cAMP levels in the CSF of AD patients were not altered. Mann–Whitney U test. AD Alzheimer’s disease, cAMP cyclic adenosine-3',5'-monophosphate, cGMP cyclic guanosine-3',5'-monophosphate, CSF cerebrospinal fluid
