High mobility group proteins are chromatin binding factors with key roles in maintenance of nuclear homeostasis. The evidence indicates that extracellularly released high mobility group box 1 (HMGB1) protein behaves as a cytokine, promoting inflammation and participating to the pathogenesis of several disorders in peripheral organs. In this study, we have(More)
Histone deacetylase inhibitors (HDACi) are emerging tools for epigenetic modulation of gene expression and suppress the inflammatory response in models of systemic immune activation. Yet, their effects within the brain are still controversial. Also, whether HDACs are expressed in astrocytes or microglia is unclear. Here, we report the identification of(More)
Poly(ADP-ribose)polymerase-1 (PARP-1) overactivation is a key event in neurodegeneration but the underlying molecular mechanisms wait to be unequivocally identified. Energy failure, transcriptional derangement and deadly nucleus-mitochondria cross-talk have been proposed as mechanisms responsible for PARP-1 neurotoxicity. In this study, we sought to(More)
High-mobility group protein box 1 (HMGB1), also know as amphoterin, is a nonhistone nuclear protein with well-established functions in gene transcription and homeostasis regulation into the cell nucleus. Interestingly, the protein can be passively released in the extracellular space during necrosis, whereas retained into the nucleus by cells undergoing(More)
