Impacto de la enfermedad de Huntington en la familia
2012
Se describen las alteraciones estructurales y emocionales de las familias con uno o más miembros enfermos de Huntington, en función de los diferentes síntomas, del afectado (descendientes, progenitores) y de las diferentes etapas. Consideramos que los servicios de ayuda a la familia deben estar compuestos por profesionales expertos en las necesidades específicas de esta enfermedad y que deben ayudar a planificar y diseñar las ayudas de manera individual, adecuada y flexible. Esta ayuda debe centrarse en superar el impacto de la enfermedad, en proporcionar información relevante, en buscar soluciones prácticas, en dar apoyo emocional, en diseñar los cuidados necesarios en cada caso y etapa, y…

Ubiquitin-independent function of optineurin in autophagic clearance of protein aggregates.
2013
Summary Aggregation of misfolded proteins and the associated loss of neurons are considered a hallmark of numerous neurodegenerative diseases. Optineurin is present in protein inclusions observed in various neurodegenerative diseases including amyotrophic lateral sclerosis (ALS), Huntington's disease, Alzheimer's disease, Parkinson's disease, Creutzfeld-Jacob disease and Pick's disease. Optineurin deletion mutations have also been described in ALS patients. However, the role of optineurin in mechanisms of protein aggregation remains unclear. In this report, we demonstrate that optineurin recognizes various protein aggregates via its C-terminal coiled-coil domain in a ubiquitin-independent m…
Expression of genes encoding the calcium signalosome in cellular and transgenic models of Huntington's disease
2013
Huntington's disease (HD) is a hereditary neurodegenerative disease caused by the expansion of a polyglutamine stretch in the huntingtin (HTT) protein and characterized by dysregulated calcium homeostasis. We investigated whether these disturbances are correlated with changes in the mRNA level of the genes that encode proteins involved in calcium homeostasis and signaling (i.e., the calciosome). Using custom-made TaqMan low-density arrays containing probes for 96 genes, we quantified mRNA in the striatum in YAC128 mice, a model of HD, and wildtype mice. HTT mutation caused the increased expression of some components of the calcium signalosome, including calretinin, presenilin 2, and calmyri…
AAV Vector–mediated RNAi of Mutant Huntingtin Expression Is Neuroprotective in a Novel Genetic Rat Model of Huntington's Disease
2008
We report the characterization of a new rapid-onset model of Huntington's disease (HD) generated by adeno-associated virus (AAV) vector–mediated gene transfer of N-terminal huntingtin (htt) constructs into the rat striatum. Expression of exon 1 of mutant htt containing 70 CAG repeats rapidly led to neuropathological features associated with HD. In addition, we report novel data relating to neuronal transduction of AAV vectors that modulated the phenotype observed in this model. Quantitative reverse transcriptase–polymerase chain reaction (RT–PCR) revealed that AAV vector–mediated expression in the striatum increased by >100-fold as compared to the endogenous htt level. Moreover, AAV vectors…
