Recently apoptotic markers have been found in Alzheimer's Disease (AD) brain. To investigate the relation between tau phosphorylation and apoptosis, immunocytochemistry of AT8 (indicating the degree of phosphorylation at the tau Ser202/Thr205 site) was quantitatively determined the degree of tau phosphorylation at the Ser202 site was monitored during(More)
Coexpression of constitutively active GSK-3beta[S9A] rescued the axonal pathology induced by overexpression of human tau in transgenic mice (Spittaels et al., (2000) J. Biol. Chem. 275, 41340-41349). We isolated dorsal root ganglion (DRG) neuronal cultures from adult tau4R- and tau4R x GSK-3beta-transgenic mice to define the mechanisms at the cellular and(More)
There is increasing evidence that apoptosis in postmitotic neurons is associated with a frustrated attempt to reenter the mitotic cycle. Okadaic acid, a specific protein phosphatase inhibitor, is currently used in models of Alzheimer's research to increase the degree of phosphorylation of various proteins, such as the microtubule-associated protein tau.(More)
Cyclic adenosine 3'5'-monophosphate (cAMP) and cyclic guanosine 3'5'-monophosphate (cGMP) serve as second messengers in several cellular pathways within the central nervous system. In various neurological and psychiatric disorders with known deficits in neurotransmission function, CSF levels of cAMP and/or cGMP in patients were studied. Very little(More)
