Degeneration of dopaminergic neurons in the substantia nigra is characteristic for Parkinson’s disease (PD), the second most common neurodegenerative disorder. Mitochondrial dysfunction is believed to contribute to the etiology of PD. Although most cases are sporadic, recent evidence points to anumberof genes involved in familial variants of PD.Amongthem, a ...

Loss of function mutations in progranulin cause tau-negative frontotemporal lobar degeneration with ubiquitin positive inclusions. A major protein component of these inclusions is TDP-43, which becomes hyperphosphorylated, ubiquitinated and cleaved to generate C-terminal fragments, which apparently translocate from nuclei to the cytoplasm. Most progranulin ...

Presenilin, the catalytic component of the gamma-secretase complex, type IV prepilin peptidases and signal peptide peptidase (SPP) are the founding members of the family of intramembrane cleaving GxGD aspartyl proteases. SPP-like (SPPL) proteases, such as SPPL2a, b, and c and SPPL3 also belong to the GxGD family. In contrast to gamma-secretase, where numerous ...

Alzheimer's disease (AD) amyloid beta-peptide (Aß) is generated via proteolytic processing of the ß-amyloid precursor protein (APP) by ß- and gamma-secretase. gamma-Secretase can be blocked by selective inhibitors but can also be modulated by a subset of non-steroidal anti-inflammatory drugs (NSAIDs) including sulindac sulfide. These drugs selectively reduce the ...

Channels directly gated by cyclic nucleotides (CNG channels) are important cellular switches that mediate influx of Na+ and Ca2+ in response to increases in the intracellular concentration of cAMP and cGMP. In photoreceptors and olfactory receptor neurons, these channels serve as final targets for cGMP and cAMP signaling pathways that are initiated by the ...

The mammalian main olfactory epithelium (MOE) recognizes and transduces olfactory cues through a G protein-coupled, cAMPdependent signaling cascade. Additional chemosensory transduction mechanisms have been suggested but remain controversial. We show that a subset of MOE neurons expressing the orphan receptor guanylyl cyclase GC-D and the cyclic nucleotide-gated ...
