Abstract
We found 35 brains with deposits of 3 proteins (tau, β-amyloid, and α-synuclein). In these two series of brains, the high incidence of deposition of multiple proteins in neurodegenerative disorders is shown. Our results are in agreement with previous findings showing that tau, β-amyloid, and α-s...

Abstract
We describe the molecular mechanisms regulating the ubiquitin proteasome system, thereby focussing on Nrf2 as well as on the recently identified transcription factor (TF) TCF11. In response to proteasome inhibition TCF11 plays a central role in upregulating the proteasome system via an ERAD-dependen...

Abstract
We identify a new parkin interacting substrate, PARIS (ZNF746), whose levels are regulated by the ubiquitin proteasome system via binding to and ubiquitination by the E3 ubiquitin ligase, parkin. PARIS is a KRAB and zinc finger protein that accumulates in models of parkin inactivation and in human P...

We describe here how conformational preferences of non-polar amino acid residues can affect amyloid formation. The most non-polar residues promote either β-strands (Val, Ile, Phe, and Cys, VIFC) or α-helices (Leu, Ala, and Met, LAM), while the most polar residues promote only α-helices. For 12 pr...

We hypothesize that secretory factors from the activated astrocytes affect N-methyl-d-aspartate (NMDA) receptor, a major pathway implicated in HIV-1-associated neurodegeneration. To test this hypothesis, we studied effects of IL-1β-stimulated astrocyte conditioned medium (ACM+) for its ability to a...
